hi all i faced a problem in one of my websites , the client upload various swf flash files with various dimension and i must embed the flash automatically by code
i found that getimagesize function work also with swf so i made it like that

<?php
    $file = "YOUR_FILE.swf";
    $info = getimagesize($file);
    $width = $info[0];
    $height = $info[1];
    print "{$width}x{$height}\n";
?>
