Finding the file extsension

[edwardp]

I am running php 4.1 on a windows machine, What functions can i use to distinguish filetypes and folders so they don't get picked up in using the readdir() functions??

Thanx in advance

<?php
// Query file name and matchup file type

$files = Array(
	0 => 'Image.jpg',
	1 => 'File.zip',
	2 => 'Image.gif',
	3 => 'Image.bmp',
	4 => 'File.exe'
);

$extension = Array(
	'.zip' => 'WinZip - Compressed',
	'.jpg' => 'JPEG Image',
	'.gif' => 'GIF Image',
	'.bmp' => 'Bitmap',
	'.rar' => 'WinRar - Compressed',
	'.exe' => 'Executable'
);

foreach ($files as $f_key => $f_value) {
	$value = strrchr($f_value,".");
	foreach ($extension as $ext_key => $ext_value) {
		if ($ext_key == $value) { echo $f_value ." => ". $ext_value ."<br>"; }
	}
}
?>

Or if you want to find out the mime type of the files contents then use [man]mime_content_type()[/man]
