I think what your looking for is the empty() function Below is an example. [CODE]<?php $arr=array('','a',0,NULL); echo '//empty<br>'; $i=1; foreach ($arr AS $val) { if (empty($val) { echo $i.' passed<br>'; } $i++; } echo '//isset<br>'; $i=1; foreach ($arr AS $vals) { if (isset($vals)) { echo $i.' passed<br>'; } $i++; } …

With the following: [CODE]ini_set('memory_limit','64M'); ini_set('max_execution_time','256'); ini_set('upload_max_filesize','60M');[/CODE]

I would suggest the following: [CODE]$zone=array('id'=>array(),'name'=>array()); while ($row=mysql_fetch_assoc($result)) { $zone['id'][]=$row['zone_id']; $zone['name'][]=$row['zone_name']; } //first index echo $zone['id'][0]; echo $zone['name'][0]; //second index echo $zone['id'][1]; echo $zone['name'][1]; [/CODE] How be sure that not much data is being stored in the array (>1MB) as you can make your script run out of memory.

Well in my opinion I don't mind helping with others homework as long as they are willing to put the effort to piecing the puzzle together. So even if there was an announcement and if people read it people would still post their homework. Why? Because there aren't very many …

It would require javascript but as for the basics I believe it would be something like the following. [CODE=html]<table> <tr onclick=javascript:showrow(1)><td></td><td id="1"></td></tr> <tr onclick=javascript:showrow(2)><td></td><td id="2"></td></tr>[/CODE] Then you would use css to hide the rows and a custom javascript function to show the rows. Hope that helps.

I do this a lot as my website is scattered between two web servers and the easiest way is with curl and file_get_contents(). You can retrieve contents from a database using [ICODE]file_get_contents('http://example.com/sql.php?key=asldfkjasldkfj&column=23')[/ICODE]. Then it will return the contents of that mysql request and you can use the url parameters as …

As far as I know it isn't possible to removes ones url history but perhaps you should consider $_POST. Then the user will need to confirm the post request and if they do you should then get the server to check if the same post request has been sent in …

I know how to make 64 bit integers but how do I make 64 megabit integers? That is a bit rate of (1024^3)*64 bits. Is this a simple job as I don't know where to begin. I thought somebody might know of a library/script that will allow custom bit rates …

The old mail function bug. The smtp only works if you have a localhost mail server.

Try making this your query and see what error mysql reports back. [CODE]$qry = "SELECT `userid`, COUNT(*) as `cnt` FROM table1, table2 WHERE userid = id GROUP BY userid ORDER BY cnt DESC LIMIT 0,10";[/CODE]

I agree. Storing a timestamp in a int field would be by far better as more functions would be available for the the job. Then after having the timestamp you can perform math operations to check dates and everything since a timestamp is number of seconds since 1980.

Well first of all place the following at the top of every php file but not the files which are being included (eg not include.php).

From the list I would say Java as it is so easy to use with the Netbeans compiler. But my favourite which isn't on the list is php/php-gtk.
