[Xcalibur]

tested, works like hell ;)

<?php 



  $path = "."; // path to your directory





  $arr  = array ();



  if ($dir = @opendir($path)) {

    while ($file = readdir($dir)) 

    {

      if ($file != "." && $file != ".." && is_file($file))

        $arr[] = $file;

    }  

    closedir($dir);

  }





  // -> enable this if you want to see all files in your directory

  //for ($i = 0; $i < count ($arr); $i++)

  //  echo $arr[$i] ."
n";



  // show random file from your directory

  echo $arr[rand (0, count ($arr)-1)];



?>

oh,.. i forgot,.. the size of this script is 517 bytes :p

Here's the code that puts the random image in my sig:

<?

//Random image generator

//Author: Weasel - www.almostsmart.com

$URL1="images/design/sig/small_logo.gif";

$URL2="images/design/sig/small_logo2.gif";

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

if(rand(1,2) == 1)

	@header ("Location: $URL1");

else

	@header ("Location: $URL2");

?>

I put that in sig.html on my server (there cant be any white space outside the code). Then in my sig field I put

<pre>

[I.MG]http://www.almostsmart.com/sig.html[/I.MG]

</pre>

thank you so much weasel.. your script works... except i have to put a php extension to it..otherwise my server doesnt recognise it for some reason..but it works.. thanks so much.. i needed it for a sig too :D

and for your script gregor.. it doesnt work.. this is what happens:

Xcalibur,...

i didn't know you did want that kind of stuff..

my functionjust prints the name of img file to the browser.. if you want a rand script for images.. it's like this:

<?php 



  $path = "."; // path to your directory





  $arr  = array ();



  if ($dir = @opendir($path)) {

    while ($file = readdir($dir)) 

    {

      if ($file != "." && $file != ".." && is_file($file) && (strrchr ($file, ".") == ".gif" || strrchr ($file, ".") == ".jpg"))

        $arr[] = $file;

    }  

    closedir($dir);

  }





  // -> enable this if you want to see all files in your directory

  //for ($i = 0; $i < count ($arr); $i++)

  //  echo $arr[$i] ."
n";



  // show random file from your directory

  @header ("Location: ". $arr[rand (0, count ($arr)-1)] ."");



?>

this script will show you a file if it is jpg or in gif format.

hey weasel.. how would you use that script if you have more than 2 images? i tried to fool around with the script, but no luck.. i suck at php.. lol

also, that script works gregor.. thanks a lot :D

[gregor]

no prob ;)

[Sleeper Veteran]

so if im reading this right i can use Gregor's script and i can call it by telling my sig to call

<pre>[IMG= [url]www.myspace.com/mysigs/sigs.htm[/url] ] </pre>

And thanks for the script:)

[Sleeper Veteran]

after trying this it did not work....... do i need to save the file as .php or should .htm work? also does the host where i am keeping the file have to support php scripting?

Thanks :)

[gregor]

that depends of your servers settings. try to save the script in php! it should work!

[Sleeper Veteran]

I managed to get a host that supports php, but for some reason it is not showing the different images, it just loads the sameone every time.... anyideas

i copied the code exactly so what am i doing wrong?

<?php 



  $path = "."; // path to your directory





  $arr  = array ();



  if ($dir = @opendir($path)) {

    while ($file = readdir($dir)) 

    {

      if ($file != "." && $file != ".." && is_file($file) && (strrchr ($file, ".") == ".gif" || strrchr ($file, ".") == ".jpg"))

        $arr[] = $file;

    }  

    closedir($dir);

  }





  // -> enable this if you want to see all files in your directory

  //for ($i = 0; $i < count ($arr); $i++)

  //  echo $arr[$i] ."
n";



  // show random file from your directory

  @header ("Location: ". $arr[rand (0, count ($arr)-1)] ."");



?>

Thanks
