check the extension of a file

[Anon]

Hi,

I stored a number of files in an array. I now want to check the extension of the files. If the extension is .jpg/ .gif/ .bmp/ .png, in other words an image the file names should be displayed. How do I filter the images from the regualar files?

You mean something like this?

$extension=substr($filename, strrpos($filename, ".")+1);
if (($extension=="jpg) or ($extension="gif") or ($extension="pgn")) {
echo ("<img src=\"$filename\">");
}

Jeeeeezus!
Will the substring freaks go away.

<?
preg_match('/^{(.*).([a-z0-9]{3,4})$/i',$file_name,} $split);
//$split is now an array as so:
//array([0]=>'file_name.ext',[1]=>'file_name',[2]=>'ext')
print_r($split);
?>

Now you can loop back and forth with this array to pick out filenames based upon extension, a far better way to go esp. when dealing with large directories.
