Better way to do this in PHP

Question

I currently have my htaccess file set to remove the file type so

www.example.com/home.php

would become,

www.example.com/home

I need to compare the url with one that I have saved in the database, I do this by,

if ($_SERVER['QUERY_STRING']) {
    $pageURL = str_replace('.php', '?', 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF'] . $_SERVER['QUERY_STRING']);
}
else {
    $pageURL = substr('http://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF'], 0, -4);
}

When I save the url in the database it gets saved as the current page url after the htaccess file has removed the .php, it is inserted using jquery ajax.

When I come to compare it, I need this to make it match in php as php doesn't take into account the htaccess changes.

Is there a better way to do this?

Answer 1

You can do:

$pageURL = rtrim($_SERVER['REQUEST_URI'], '.php');

This would give your url with .php removed whenever it appears at the end of the url.

Answer 2

Look into the parse_url() function. You can use it to parse the URL into parts then modify the path component (eg remove .php). Then you can rebuild the URL from those parts using the http_build_url() function.

在我看来，结合John的使用parse_url()以及使用pathinfo（）的建议将是最好的 - 修剪，使用substr的截断等并不总是像pathinfo()那样优雅。
