Rewrite a URL using preg_replace function

Question

I have a url say like http://www.something.com/folder_path/contacts.php/ ( starting with http:// and ending with .php/ ). Please make sure about the slash(/) at the end of the URL.
Now I want to rewrite the URL by replacing the last element of URL i.e. /contacts.php/ to /index.php/ by matching it using regular expression.

Example code -

$url = "http://www.something.com/folder_path/contacts.php/";
$new_element = "index.php";

$regex = "#[^/.*](\.....?)/$#"; // what would be the regular expression 

$new = preg_replace($regex,$new_element, $url);

The result would be http://www.something.com/folder_path/index.php/

also the path could be longer..all I need to replace is the last part of the URL. Thanks.

This can be done without regular expressions as well, using implode and explode. This should work-

$url = "http://www.something.com/folder_path/contacts.php/";
$arr = explode("/",$url);
$new_element = "index.php";
$arr[count($arr) - 2] = $new_element;
echo implode("/",$arr);
// Prints - http://www.something.com/folder_path/index.php/

Thanks . I already did this. But I wanted to do it by regex specifically.

This regex: $regex = "#[^/.*](\.....?)/$#"; is not matching contact.php. You should use:

$regex = "#[^\/]+\.php\/?$#";

This is matching any character except / + .php + / (optional) + END Of STRING

Yeah..thanks a lot..it worked. :D Can you explain me the Regular expression before .php please?

Manolo Over a year ago

[^\/]+ means any character except / . / must be escaped (\/). [^a] is any character except a or [^a-z] is any character except a, b, c, ..., z or [^abc] is any character except a, b, c ...

Thanks @manolo though I forgot to mention that extension may vary in original URL so i extended your answer to $reg = "#[^\/]+\..{3,4}\/$#";

@DevUtkarsh Are you sure that works? Check this out... or this. I mean, it's replacing the slash at the end.

@jerry - my target was to append the new element in original URL. It doesn't matters what the appended URL results in. I only had to take care of slash(/) in original URL because I was writing the regex for it .. :)
