setting array's

[Anon]

i have the following code which reads the contents of a dir and outputs it - how do i set it in an array ?

<?php
$list=opendir('./images/rg');
while (false!==($file = readdir($list))) {
if ($file != "." && $file != "..") {
$a=$file;
print"$a";

}
}
?>
produces the following img's from my dir -
r10.jpg r02.jpg r03.jpg r04.jpg r05.jpg r06.jpg r07.jpg r08.jpg r09.jpg r01.jpg

if i work outside of the loop it only picks up the last record

i want to be able to set the images in an array so that i can randomly pick one, any ideas on setting this to a fixed array ??

thanks

Turn this :

$a=$file;
print"$a";

Into this :

$images[] = $file;

And now $images is an array as such :

$images[0] = r10.jpg
$images[1] = r02.jpg
...

Hey Darren,

You may want to try this :

<?php

function getImages($dir)
{

if ( is_dir($dir) ) {

$fd = opendir($dir);

    while ( ( $part = @readdir($fd)) == TRUE ) {

    clearstatcache();

        if ( eregi("(gif|jpg|png|jpeg)$",$part) ) {

            $my_images[] = $part;

        }
    }

Return $my_images;

} else {

    Return ' This : <b>' . $dir . '</b> is not a directory for getImages() ';
}

}

// Here's an example use :

$array_of_images = getImages('/path/to/images/dir/');

?>

It should make sense. It will only stick designated image types (gif|jpg|png|jpeg) into the array so any file can be in the directory. It's another option at least (read: may be overkill), use and modify as you wish.
