How do I clear header URIs using PHP?

I am programming a blog and I want the URIs to be a title like the title of a question here on stackoverflow or like wordpress.
What are the rules for sanitizing URIs?
Is there any code already made in PHP that does this?

Thanks in advance,
Omer

Many CMS have implemented something like this, one from Wordpress was posted in another question . You may be wondering about this method too .

This might be the shortest way to replace any alphanumeric character with a single hyphen:



trim(preg_replace('/[^a-z0-9-]+/', '-', strtolower($str)), '-')

Here's how drupal does it .

In case of site failure:

<?php
function pathauto_cleanstring($string)
{
    $url = $string;
    $url = preg_replace('~[^\\pL0-9_]+~u', '-', $url); // substitutes anything but letters, numbers and '_' with separator
    $url = trim($url, "-");
    $url = iconv("utf-8", "us-ascii//TRANSLIT", $url); // TRANSLIT does the whole job
    $url = strtolower($url);
    $url = preg_replace('~[^-a-z0-9_]+~', '', $url); // keep only letters, numbers, '_' and separator
    return $url;
}

Typically, you only want your URL to have 0-9 and az, and make sure everything is lowercase. Replace spaces with dotted lines (-) and split the remainder of the gibberish.

SO pretty much figured it out.
