List Files In a Directory Using PHP

This handy PHP script will print out all the specified files (.jpg and .png):

<?php
// open this directory
$myDirectory = opendir(".");

// get each entry
while($entryName = readdir($myDirectory)) {
$dirArray[] = $entryName;
}

// close directory
closedir($myDirectory);

// count elements in array
$indexCount = count($dirArray);

// sort 'em
sort($dirArray);

// print 'em

// loop through the array of files and print them all
for($index=0; $index < $indexCount; $index++) {
if ((substr("$dirArray[$index]", -4, 4) == ".jpg") || (substr("$dirArray[$index]", -4, 4) == ".png")){ // only list jpg and png files
print('<img src="'.$dirArray[$index].'">');
}
}

?>
