$dir = './';
$files = array();
$file = '';
if ( is_dir($dir) ) {
if ( $d = opendir($dir) ) {
while ( ($file = readdir($d)) !== false ) {
if ( !is_dir($file) ) $files[] = $file;
}
}
}
// specify an int for the optional 2nd arg if you
// need more than one random file
$randomKeys = array_rand($files);
$randomFile = $files[$randomKeys[0]];
$files holds an array of all files in the directory specified in the
$dir variable. This can take the place of scandir if you're running on
a version of PHP prior to 5.x.
