Hi there all

You can do it like this:
[code]$var = explode('.',$filename);
$extension = $var[count($var)-1];
echo $extension;[/code]

Thanx it works

or, an alternate method:
[code]
<?php
$ext = substr($filename, strrpos('.', $filename));
?>
[/code]

Doesn't work.
[code]<?php
$filename = "mysql.db.php";
$ext = substr($filename, strrpos('.', $filename));
echo $ext;
?>[/code]
outputs [quote=code output]mysql.db.php[/quote]

my bad, i switched the arguments for strrpos:
[code]
<?php
$filename = "mysql.db.php";
$ext = substr($filename, strrpos($filename, '.')+1);
echo $ext;
?>
[/code]

you could also just use a preg_match:
[code]
<?php
$filename = "mysql.db.php";
preg_match('|\.([a-z]+)$|i', $filename, $match);
$ext = $match[1];
?>
[/code]

[printf]

Just another way...

[code]$ext = str_replace ( '.', '', strrchr ( $file, '.' ) );[/code]
