Remove everything from a string after the third slash

[Mcod]

Hello,

 

I am trying to find out how to remove everything from a string after the third slash.

 

Example:

http://domain.com/test.html would become http://domain.com/

 

one/two/three/four/five/ would become one/two/three/

 

Your help is greatly appreciated

 

Thank you!

You would be better off using parse_url

<?php
$text = 'http://www.somedomain.com/blah/blah/blah';
$parts = parse_url($text);
echo $parts['scheme'] . '://' . $parts['host'] . '/';

 

For the regex version, this will do it

<?php
$text = 'http://www.somedomain.com/blah/blah/blah';

$result = preg_replace('~^(.*?//.*?/).*$~', '$1', $text);
echo $result;

Neither of the above will handle your second case.  You want:

echo preg_replace('#^(.*?/.*?/.*?/).*$#', "\\1", $yourString);

non-regex on-liner alternative:

 

$string = implode("/",array_slice(explode("/",$string,4),0,3));

Josh's way is faster than mine, but he trims the trailing slash.  You'll have to re-add it.

If the string is coming from a database, you could also do it in the query string with this

 

SELECT CONCAT( SUBSTRING_INDEX(`field_name`, '/', 3), '/' )
