maar hoe zorg ik dat hij alle gif bestanden uit een map uitleest?
want ik zocht op phphulp maar dan staat nergens hoe je de extentie kan checken

[COLOR= #0000BB]<?php[/COLOR]
[URL="http://www.php.net/foreach"]foreach[/URL] [COLOR= #007700]([/COLOR][URL="http://www.php.net/glob"]glob[/URL][COLOR= #007700]([/COLOR][COLOR= #DD0000]MAP/{*.gif}[/COLOR][COLOR= #007700],[/COLOR] GLOB_BRACE[COLOR= #007700]) as[/COLOR] [COLOR= #0000BB]$filename[/COLOR][COLOR= #007700]) {[/COLOR] 

   [URL="http://www.php.net/echo"]echo[/URL] [COLOR= #DD0000]<img src="[/COLOR][COLOR= #007700].[/COLOR][COLOR= #0000BB]$filename[/COLOR][COLOR= #007700].[/COLOR][COLOR= #DD0000]" alt="" />[/COLOR][COLOR= #007700]; 

}[/COLOR]  
?>

hoe zorg ik ervoor dat bij dit:

[COLOR= #0000BB]<?php[/COLOR]
[URL="http://www.php.net/foreach"]foreach[/URL] [COLOR= #007700]([/COLOR][URL="http://www.php.net/glob"]glob[/URL][COLOR= #007700]([/COLOR][COLOR= #DD0000]img/{*.gif}[/COLOR][COLOR= #007700],[/COLOR] GLOB_BRACE[COLOR= #007700]) as[/COLOR] [COLOR= #0000BB]$filename[/COLOR][COLOR= #007700]) {[/COLOR] 

   [URL="http://www.php.net/echo"]echo[/URL] [COLOR= #DD0000]<a href="javascript:EmotionsDialog.insert([/COLOR][COLOR= #007700].[/COLOR][COLOR= #0000BB]$filename[/COLOR][COLOR= #007700].[/COLOR][COLOR= #DD0000],emotions_dlg.smile);"><img src="[/COLOR][COLOR= #007700].[/COLOR][COLOR= #0000BB]$filename[/COLOR][COLOR= #007700].[/COLOR][COLOR= #DD0000]" alt="" border="0" /></a>[/COLOR][COLOR= #007700]; 

}[/COLOR]
[URL="http://www.php.net/exit"]exit[/URL][COLOR= #007700];[/COLOR]
?>

ik ervoor zorg dat de map eruit wordt gehaald bij de klik?
