Default case in switch() can't be blank, so or you remove it or you assign an action.

Check inside IE/front-page.php or post that code. The error is there.

You can use get_browser(): http://php.net/manual/en/function.get-browser.php
But the client can spoof the user agent, so don't trust what you get and always sanitize the data, because an XSS attack can be performed.

Fine, mark the thread as solved, bye :)

is this correct. My image is not loading on right. A red cross(X) sign is coming.

$imagepath = "shirt7.jpg"; # check this!

Then check the path. Is your image in the same directory of your script file?

oops! Hi Ardav ;D

Basically you can add style="float:right;" to img tag. This thread is related more to CSS forum than PHP, I suggest you to move it, bye :)

It seems you need to change the setting for maxRequestLength attribute which is found both in Machine.config and Web.config, this last file should be site specific, anyway check these links:

- http://masstechnical.com/Blog/tabid/100/EntryId/7/IIS-7-5-Setting-for-File-Upload-Size.aspx
- http://www.iis.net/ConfigReference/system.webServer/security/requestFiltering/requestLimits
- http://support.microsoft.com/default.aspx?scid=kb;EN-US;295626

or just search on google for "IIS 7.5 upload file size limits", I can't help more than this, bye.

How much large are these files? IIS limits uploads to 30MB by default and maximum upload should be around 2GB.

If you are referring to the e-commerce platform then look at system requirements:

- http://www.magentocommerce.com/system-requirements

it works only on linux. Bye.

From: http://php.net/manual/en/function.create-function.php

Usually these parameters will be passed as single quote delimited strings. The reason for using single quoted strings, is to protect the variable names from parsing, otherwise, if you use double quotes there will be a need to escape the variable names, e.g. \$avar.

bye :)

Just an update on function start() this will speed up the execution and use less memory:

public function start($arrayA,$arrayB)
    {
        global $a;
        global $b;
        global $c;
        
        $replace = array(',',' ','','-');
        $a = str_split(str_replace($replace,'',$arrayA));
        
        if(empty($arrayB))
        {
            $bArr = false;
            $b = array();
        } else {
            $bArr = true;
            $b = str_split(str_replace($replace,'',$arrayB));
        }
        
        $c = ($bArr == false) ? $a : array_merge($a,$b);
        
        if(count($c) > 5)
        {
            return 'too long';
        }
        elseif(count($c) <= 1)
        {
            return 'too short';
        }
        else
        {
            $size = count($c)-1;
            $perm = range(0, $size);
            $j = 0;

            do
            {
                foreach ($perm as $i) { $perms[$j][] = $c[$i]; }
            }
            while($perm = $this->p($perm, $size) and ++$j);
            
            $list = array_map('join',$perms);
            $list = array_unique($list);
            $list = array_merge(array(),$list);
            $list = array_unique($this->ps($list));
            $result = array_merge(array(),$list);
            
            return $result;
        }
    }

The permutation function p() creates a lot of duplicates, so using $list = array_unique($list); helps to reduce data sent to function ps(). Bye.

So if you set rde you want to get only:

Array
(
    [0] => red
    [1] => dre
    [2] => de
    [4] => re
    [9] => ed
    [12] => der
    [21] => er
)

Am I right? If yes maybe we got it, now there is a function at the end, that will check only for words containing set letters:

<?php
Class Perm
{
    
    public function start($arrayA,$arrayB)
    {
        global $a;
        global $b;
        global $c;
        
        $replace = array(',',' ','','-');
        $a = str_split(str_replace($replace,'',$arrayA));
        
        if(empty($arrayB))
        {
            $bArr = false;
            $b = array();
        } else {
            $bArr = true;
            $b = str_split(str_replace($replace,'',$arrayB));
        }
        
        $c = ($bArr == false) ? $a : array_merge($a,$b);
        
        if(count($c) > 5)
        {
            return 'too long';
        }
        elseif(count($c) <= 1)
        {
            return 'too short';
        }
        else

            $size = count($c)-1;
            $perm = range(0, $size);
            $j = 0;

            do {
                 foreach ($perm as $i) { $perms[$j][] = $c[$i]; }
            } while ($perm = $this->p($perm, $size) and ++$j);

            $list = array();
            foreach ($perms as $p) {
                $list[] = join('', $p);
            }
            
            return array_unique($this->ps($list));
        }
    }
    
    # generate permutations
    private function p($p, $size) {
        for ($i = $size-1; @$p[$i] >= $p[$i+1]; --$i) { }
        if ($i == -1) { return false; }
        for ($j = $size; $p[$j] <= $p[$i]; --$j) { }

        $tmp = $p[$i];
        $p[$i] = $p[$j];
        $p[$j] = $tmp;

        for (++$i, $j = $size; $i < $j; ++$i, --$j) {
             $tmp = $p[$i];
             $p[$i] = $p[$j];
             $p[$j] = $tmp;
        }

        return $p;
    }

    # count and compare values between array a and …

Update class function ps() with this:

private function ps($list)
    {
        global $a;
        global $b;
        $n = count($list);
        $pspell_config = pspell_config_create("en");
        
        # Available flags:
        #
        # PSPELL_FAST
        # PSPELL_NORMAL
        # PSPELL_BAD_SPELLERS # this will slow down the script
        #
        pspell_config_mode($pspell_config, PSPELL_BAD_SPELLERS);
        $pspell_link = pspell_new_config($pspell_config);
        $z = array();
        for($i = 0; $i < $n; $i++)
        {
            $suggestions = pspell_suggest($pspell_link, $list[$i]);
            foreach ($suggestions as $suggestion)
            {
                if(strlen($suggestion) > 1)
                {
                    $s = strtolower($suggestion);
                    $this->d($s,$a);
                    $this->e($s,$b);
                      
                    if($this->c($s,$a) == true && ctype_alpha($s))
                    {
                        $z[] = $s;
                    }
                }
                    
            }        
        }
        return $z;
    }

You can increase results by setting flags in pspell config as explained here: http://www.php.net/manual/en/function.pspell-config-mode.php
If it still doesn't match, please provide an example. Bye :)

Wait, one problem at a time.
An update on the class:

<?php
Class Perm
{

    public function start($arrayA,$arrayB)
    {
        global $a;
        global $b;
        
        $replace = array(',',' ','','-');
        $a = str_split(str_replace($replace,'',$arrayA));
        
        if(empty($arrayB))
        {
            $bArr = false;
            $b = array();
        } else {
            $bArr = true;
            $b = str_split(str_replace($replace,'',$arrayB));
        }
        
        $c = ($bArr == false) ? $a : array_merge($a,$b);
        
        if(count($c) > 5)
        {
            return 'too long';
        }
        else
        {
            $size = count($c)-1;
            $perm = range(0, $size);
            $j = 0;

            do {
                 foreach ($perm as $i) { $perms[$j][] = $c[$i]; }
            } while ($perm = $this->p($perm, $size) and ++$j);

            $list = array();
            foreach ($perms as $p) {
                $list[] = join('', $p);
            }
            
            return array_unique($this->ps($list));
        }
    }
    
    # generate permutations
    private function p($p, $size) {
        for ($i = $size-1; @$p[$i] >= $p[$i+1]; --$i) { }
        if ($i == -1) { return false; }
        for ($j = $size; $p[$j] <= $p[$i]; --$j) { }

        $tmp = $p[$i];
        $p[$i] = $p[$j];
        $p[$j] = $tmp;

        for (++$i, $j = $size; $i < $j; ++$i, --$j) {
             $tmp = $p[$i];
             $p[$i] = $p[$j];
             $p[$j] = $tmp;
        }

        return $p;
    }

    # count and compare values between array a and word 
    private function d($word, $array)
    {
	    global $d;
	    $u = array_unique($array);
	    $w = str_split($word);
     
	    $u2 = array_intersect($u,$w);
	    $a1 = array_count_values($array);
	    $w1 = array_count_values($w);
	    $a = array();
	    foreach($u2 as $k => $v)
	    {
        	$a[] = ($a1[$v] >= $w1[$v]) ? true:false;
	    }
     
	    $d = in_array(false,$a) ? false:true;
	    return $d;
    }
     
    # check array b
    private function e($word,$barray)
    {    
	    global $e; …

Just an add, on line 178 of the class you can change the conditional statement to:

if($this->c($s,$a) == true && ctype_alpha($s))

this will remove results like root's, odor's and the others.

Ok, I changed permutation function, it's taken always from that article: http://docstore.mik.ua/orelly/webprog/pcook/ch04_26.htm
Previously it was hard to return the output from the function, now I created a class:

<?php
# filename perm.class.php

        }
        else
        {
            $size = count($c)-1;
            $perm = range(0, $size);
            $j = 0;

            do {
                 foreach ($perm as $i) { $perms[$j][] = $c[$i]; }
            } while ($perm = $this->p($perm, $size) and ++$j);

            $list = array();
            foreach ($perms as $p) {

            }

             $tmp = $p[$i];
             $p[$i] = $p[$j];
             $p[$j] = $tmp;
        }

        return $p;
    }

	    $u2 = array_intersect($u,$w);
	    $a1 = array_count_values($array);
	    $w1 = array_count_values($w);
	    $a = array();
	    foreach($u2 as $k => $v)
	    {
        	$a[] = ($a1[$v] >= $w1[$v]) ? true:false;
	    }
     
	    $d = in_array(false,$a) ? false:true;

This works without errors, unless input is too long and the execution time goes over 30 seconds, at that point PHP will stop the script and return part of the output and an error. For this reason I added a length check at the end of the script, otherwise you have to increase max_execution_time.

I'm sorry, now it should work like you want:

do the same for the images. If you replace spaces with underscore, remember also to rename the uploaded files. you can use mv() function. Bye.

That's normal, use http://php.net/manual/en/function.urlencode.php
Or replace the spaces with an underscore, you can use str_replace(), bye

Set global both sides:

function a()
{
        global $b;
        echo $b;
}

function c()
{
        global $b;
        $b = 'hello world';
        return $b;
}

c();
echo a();

Try this:

<?php

$a = array('test','text','ext','tex','deer'); # words to filter
$b = array('e','s','t','d','r'); # letters to check

function c($letter,$array)
{
        $n = strlen($letter);
        $r = array();
        for($i = 0; $i < $n; $i++)
        {
                if(in_array($letter[$i],$array))
                {
                        $r[] = true;
                }
                else

        return (in_array(null,$r)) ? false:true;

foreach($a as $word)
{
        echo $word .': '. c($word,$b) . "\n";
}
?>

bye.

Don't worry Ardav, you're not alone, I understood the same of you.. ;p

define $total outside the loop: $total = ''; bye.

In addition search for "MySQL hardening" to enhance MySQL config and try RatProxy to test your application: http://code.google.com/p/ratproxy/

put $AE++ inside the loop.

The table name is "database"? check if your query is right. Bye.

As Pritaeas suggested here is an example code for MySQL shell:

mysql> select password('test');
+-------------------------------------------+
| password('test')                          |
+-------------------------------------------+
| *94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29 |
+-------------------------------------------+
1 row in set (0.00 sec)

mysql> create user 'dreamsin'@'localhost' identified by '*94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29';

mysql> grant select, insert, update, delete, create, create view, drop, alter on db_name.* to dreamsin@localhost;

here you setup a single user for reading, inserting, creating tables inside a database, but if you can, create separated users: readonly (only select), application (select, insert, update, delete) and administration (previous privileges plus create, create view, drop and alter) it will be better.

+ http://dev.mysql.com/doc/refman/5.5/en/grant.html

Remove the $ sign at lines 95 and 96:

$title = $row["searchtype"];
$price = $row["price"];

bye

hehe :)
you're welcome, bye.

This article is a good start: http://devzone.zend.com/1254/getting-started-with-openid-and-php/

I did it once, for a project in which I adopted Janrain solution (most because I could not use the PEAR package): http://www.janrain.com/
This plugin remembers the user (even after logout) and when he comes back gives a suggestion.

In that project, users had the ability to create a standard account or to log with an available OpenID (Flickr, Twitter, Yahoo, Google, Windows Live and MySpace).

If that was first login from openID and there was no match with a standard accounts, then it was created a new account. Otherwise, the user was suggested to merge it with the matched account. Anyway, if the user had also a standard account he had the ability to merge the account.

A (requested) nightmare :S

Virtually, in that project, a user can login with many OpenIDs and link always to the same standard account.

To fully enable an account created with an OpenID, it was requested to complete the login inserting an email, usually from the OpenId service you get enough data but sometimes, as with Twitter, you don't get any email address. So, for this reason, it was requested.

Once you have an email and the user choose to login with Facebook and Twitter and Google and whatever else, when he completes with the same email you can merge the accounts..

I repeat: a requested nightmare :'(

Anyway, if you want …

<?php
$brush_price = 5;
$quantity = 10;
$total = $brush_price * $quantity;
echo "<table border=\"1\" align=\"center\">
<tr><td>Quantity</td><td>Price</td></tr>
<tr><td>$quantity</td><td>$total</td></tr>";
?>

Bye.

Add a loop:

$Families = array ( "Farhad" =>array("Ali","Haider","Kashan"), "Sufyan" => array("Shahbaz","Ali2","Azaan"));
 
foreach($Families as $key2=>$values3)
{
        foreach($values3 as $v)
        {
            echo "$key2 $v";
        {
}

bye :)

I think you need to use imagesavealpha(): http://php.net/manual/en/function.imagesavealpha.php
Place it just before imagepng(). Bye :)

Maybe I did not understand your question, can you paste the code?

You have to use switch() inside your index.php, an example:

<?php
$action = $_GET['action'];
switch($action) {
    case 'login':
    # code for login page
    break;
    case 'index':
    default:
    # code for home page
}
?>

http://php.net/manual/en/control-structures.switch.php

Why all those quotes? Rewrite your statements:

if($_POST['type_id'] == FALSE && $_POST['location_id'] > 0 && $_POST['bedroom_id'] > 0 && $_POST['price_id'] > 0)

Yes:

<input type="radio" name="button1" value="On" onClick="submit();" <?php echo ($_POST['button1'] == 'On') ? 'checked="checked"' : ''; ?> /> On
	<input type="radio" name="button1" value="Off" onClick="submit();" <?php echo ($_POST['button1'] == 'Off') ? 'checked="checked"' : ''; ?> /> Off

bye!

Set the same name attribute to both input:

<input type="radio" name="button1" value="on" /> on
<input type="radio" name="button1" value="off" /> off

And in PHP side check for $_POST value, bye.

So it seems, I've tried this and hello is not printed:

<?php
echo <<<HTML
test 1
<?php echo 'hello'; ?>
test 2
HTML;
?>

On last file try to move session_start(); at very top of the file. Bye.

It seems ok but I don't see the form, so check if there is something different between field names and $_POST vars. Bye :)

profpic is the image name or the image itself? What kind of column is profpic: blob or varchar?

Add imagejpeg(): http://php.net/manual/en/function.imagejpeg.php
bye :)

Check these links: http://phpxmlrpc.sourceforge.net/doc-1.1/ch05s02.html & http://phpxmlrpc.sourceforge.net/doc-2/ch07s02.html (updated version)

The constructor takes the following form:

$msg=new xmlrpcmsg( $methodName,
$parameterArray);
$methodName;
$parameterArray;
Where methodName is a string indicating the name of the method you wish to invoke, and parameterArray is a simple Array of xmlrpcval objects.

where $methodName is 'execute' in your example. Bye :)

From substr() manual:

string substr ( string $string , int $start [, int $length ] )
If length is given and is 0, FALSE or NULL an empty string will be returned.

The problem is related to substr() on line 6, because strrpos() returns FALSE when there are no spaces:

$string = substr($string, 0, strrpos($string, ' '));

therefore you have substr('nospacestring',0,false) In order to solve change that line with this, which makes use of ctype_space():

if(ctype_space($string))
{
   $string = substr($string, 0, strrpos($string, ' '));
}

bye :)
