URL rewriting in PHP involves modifying server configuration files to make URLs appear cleaner and more user-friendly.

How to Rewrite URLs in PHP

In PHP, we can use the parse_url() and http_build_url() functions to parse and construct URLs. Here's a simple example:

<?php
// Original URL
$url = 'https://www.example.com/path?query=value';
// Using parse_url() function to parse the URL
$parsed_url = parse_url($url);
print_r($parsed_url);
?>

Output:

Array(
    [scheme] => https
    [host] => www.example.com
    [port] =>
    [user] =>
    [pass] =>
    [path] => /path
    [query] => query=value
    [fragment] =>
)

Next, we can use the http_build_url() function to rewrite the URL:

<?php
// Original URL
$url = 'https://www.example.com/path?query=value';
// Using http_build_url() function to rewrite the URL
$rewritten_url = http_build_url($url, array('query' => 'new_value'));
echo $rewritten_url;
?>

Output:

https://www.example.com/path?query=new_value
