what is the *fastest* method to extract directory from url ?

[madrazel]

given is string:

 

http://www.server.com/dir/dir2/dir3/file.html

or

myname@domain.com

 

and result should be:

 

http://www.server.com/dir/dir2/dir3/

or

myname@

 

how to make it *really fast* without strrev and strstr ?

[MadTechie]

i guess without strrev and strstr,

 

this will work

 

<?php
#$subject = "http://www.server.com/dir/dir2/dir3/file.html";
$subject = "myname@domain.com";

$result = eregi_replace('(.*@).*', '\\1', $subject);
$result = eregi_replace('(.*\\/)(.*)[^\\/]+$', '\\1', $result);

echo "$result<br />";
?>

 

Please note i am still learning eregi so am use them when i can, so this was kinda pratice for me
