Random text display with image, link

[Hjcooke]

Hi, im creating a website at the moment and i want to use this php code to create random effects on my page when its refrshed. Im using this php code which enetrs random text into a web page stored rom a flat file. Can any one help me, and customise it further so a corresponding image and even a link can be displayed as well.

<?php


$RANDOM_TXT_FILE = "sample_data.txt";

srand((double)microtime()*1000000);

if (file_exists($RANDOM_TXT_FILE)) {
    $arry_txt = preg_split("/--NEXT--/", join('', file($RANDOM_TXT_FILE)));
    echo $arry_txt[rand(0, sizeof($arry_txt) -1)];
} else {
    echo "Error: can't open $RANDOM_IMG_FILE file";
}

?>

Man.y thanks

i don't know if this will help, but have you considered using javascript to make random events? (it would be easy to make a random image accompany a link using js.)

something else you could do (since i've never used preg_split)....

this requires that every new line have the code that you want on it so if your content spans two lines, then make sure you check if $random_line is even, if not then add one to it, etc..., etc...

show me a few lines of your file and i can see if ican help modify this code to better suit your needs

$RANDOM_TXT_FILE = "sample_data.txt";
if (file_exists($RANDOM_TXT_FILE))
{
   $file = file($RANDOM_TXT_FILE);
   srand((double)microtime()*1000000); 
   $random_line = rand(0,sizeOf($file));
   echo $file[$random_line];
}
//else - no file
//no need to look like and idiot and print an error to our users
//we should use fwrite and log this to a file instead
//or incorporate some other way to log this error

here is the copy of the text file i used,
line one: entire text ad
line two: link to website
line three: image link

all new ads must start on lines 1,6,11,....
5 lines between each ad, which gives you two empty slots to grow into

and here is the php code, which i just dumped into a function:

<?
function getRandomText()
{
   $r = 0;
   $RANDOM_TXT_FILE = "sample_data.txt";
   if (@file_exists($RANDOM_TXT_FILE))
   {
      $file = @file($RANDOM_TXT_FILE);

      srand((double)microtime()*1000000);
      $random = 5 * rand(0, (int) (sizeOf($file)/5));
      unset($r);

      $r['text'] = $file[$random];
      $r['link'] = $file[++$random];
      $r['img'] = $file[++$random];
   }
   return $r;
}


$random_text = getRandomText();
if (is_array($random_text)) 
{
   echo "<a href=".$random_text['link']." ><img src=".$random_text['img']." ></a> - ".$random_text['text'];
}
?>

i sure hope this makes sense, if you start making this any more complicated then I stronly recomment moving this into a database otherwise this will work. if you have any questions with any of the lines of code above let me know and i will explain it to the best of my knowledge

hi, nice.

One question though,

what if i want the code

<?
function getRandomText()
{
   $r = 0;
   $RANDOM_TXT_FILE = "sample_data.txt";

see the sample_data.txt well mine is in another folder like episodes/episodesmenu.txt but also when others go to other pages, i want it to load the same thing but it comes out blank. I mean in the index page it works fine because it actually finds the episodes/ folder and text, but when im in page like http://www.domain.com/episodes/pullingtogether.php it wont show because it is looking for the directory episodes/ and text file. i tried adding a slash to the code like so

<?
function getRandomText()
{
   $r = 0;
   $RANDOM_TXT_FILE = "/episodes/sample_data.txt";

still no luck, it doesnt load in the index nor other pages.

i also tried and put the url of the site in there like so

<?
function getRandomText()
{
   $r = 0;
   $RANDOM_TXT_FILE = "http://www.domain.com/episodes/sample_data.txt";

and it doesnt show anything at all in the index nor other pages.

Please help friend, i love this code, and really need it.
