Using same function 2nd time - php

Question

I'm declaring the following function to get a random image from a directory. I want to use the same function in same code to get random image from a different directory. Now the problem is that I have to change $path but I have already used it in declaration while i want to use the different path when I use the function 2nd time
Declaration part
function getImagesFromDir($path) {
$images = array();
if ( $img_dir = #opendir($path) ) {
while ( false !== ($img_file = readdir($img_dir)) ) {
// checks for gif, jpg, png
if ( preg_match("/(\.gif|\.jpg|\.png)$/", $img_file) ) {
$images[] = $img_file;
}
}
closedir($img_dir);
}
return $images;
}
I use it this way 1st time
$root = '';
$path = 'frames/';
$imgList = getImagesFromDir($root . $path);
$img = getRandomFromArray($imgList);
How shud i use it 2nd time so that it chooses image from different directory.

Probably you don't call the function twice, but declare it twice.
declaration:
function getImagesFromDir($path) {
$images = array();
if ( $img_dir = #opendir($path) ) {
while ( false !== ($img_file = readdir($img_dir)) ) {
// checks for gif, jpg, png
if ( preg_match("/(\.gif|\.jpg|\.png)$/", $img_file) ) {
$images[] = $img_file;
}
}
closedir($img_dir);
}
return $images;
}
calls:
$images1 = getImagesFromDir("/var/www/images1");
$images2 = getImagesFromDir("/var/www/images2");
if you write
function getImagesFromDir($path) ....
again anywhere it gets redeclared and PHP don't supports this
this also happens if you require the file, which declares the function, more than once.

$strRoot = '';
$astrImages = array();
$astrImages[] = array( 'path' => 'frames/', 'image' => '' );
$astrImages[] = array( 'path' => 'etc1/', 'image' => '' );
$astrImages[] = array( 'path' => 'etc2/', 'image' => '' );
$astrImages[] = array( 'path' => 'etc3/', 'image' => '' );
foreach( $astrImages as $nIndex => $astrImage )
{
$imgList = getImagesFromDir($strRoot . $astrImage['path']);
$astrImages[$nIndex]['image'] = getRandomFromArray($imgList);
}
