preg_match to split url

[ted_chou12]

Hi, how can a preg_match code that split a url into domain, page at once?

I found:

preg_match('@^(?:http://)?([^/]+)@i', $link, $final);

This doesnt work, only get rid of the http://, I wish to come up with something that deletes "http://" and splits the rest of the url to two parts, the domain and the page:

http://phpfreaks.com/forums/page12.php

The result can be something like:

echo $final[0] gives phpfreaks.com/

echo $final[1] gives forums/page12.php

Thanks,

Ted

For things like this, you don't need regex. You can utilize parse_url() instead.

 

$url = parse_url('http://phpfreaks.com/forums/page12.php');
echo '<pre>';
   print_r($url);
echo '</pre>';

 

output:

Array
(
    [scheme] => http
    [host] => phpfreaks.com
    [path] => /forums/page12.php
)

 

So in otherwords, you can simply output something like:

echo $url['path']; // which outputs: /forums/page12.php

EDIT: In the event you don't want the first slash in $url['path'], you can instead echo like this:

echo substr($url['path'], 1, strlen($url['path'])-1); // ouputs: forums/page12.php

Thanks, that helps a lot^^~~

No problem.

nrg_alpha, the strlen call isn't needed since if it is excluded, the length will be assumed.

You're right. I stand corrected.  :-\

It would work fine, just not needed.  Was about to say no need for an extra function call, but then I realized something similar to strlen is probably called in the internals of substr anyway ;p.  Just something that caught my eye.  Not a biggie.

It's good that you caught that though 

I learned something new (as you can tell, I don't make use of substr() often). But know I know there's no need for that extra parameter.. makes coding-life easier for sure. Thanks again for the insight.
