PHP: How to strip all types of extensions from URL (incl. period)

Question

I am new to PHP and hope someone can help me with this.

I want PHP to give me the name of the current page of my website. The important thing is that I need this without any leading slashes and without any trailing extensions etc., just the plain page name.

Example:
The URL of a page is http://www.myurl.com/index.php?lang=en In this case it should only return "index".

I found a way to get rid of the leading part using the following but have trouble to remove the trailing part since this is variable (it can be just .php or .php?lang=en or .php=lang=de etc.).

$pageName = basename($_SERVER["REQUEST_URI"]);

The only thing I found is the following but this doesn't cover the variable extension part:

$pageName = basename($_SERVER["REQUEST_URI"], ".php");

Can someone tell me how to get rid of the trailing part as well ?

Many thanks in advance, Mike

Answer 1

You can use parse_url in combination with pathinfo:

<?php
$input  = 'http://www.myurl.com/index.php?lang=en';
$output = pathinfo(parse_url($input, PHP_URL_PATH), PATHINFO_FILENAME); 

var_dump($output); // => index

Answer 3

One possible way is:

$url = "http://www.myurl.com/index.php?lang=en";

preg_match('/\/([\w-_]+)\.php/i',$url,$match);
echo $match[1];

Answer 4

here is simplest solution.

$pagename = basename($_SERVER['PHP_SELF']);
$a = explode(".",$pagename);
echo $a[0];

Answer 5

Try this

//return url
$pageName = base64_decode($_GET["return_url"]);

function Url($pageName) {
    $pageName= strtolower($pageName);
    $pageName= str_replace('.',' ',$pageName);
    $pageName= preg_replace("/[^a-z0-9_\s-]/", "", $pageName);
    $pageName= preg_replace("/[\s-]+/", " ", $pageName);
    $pageName= preg_replace("/[\s_]/", "-", $pageName);
    return $pageName ;
}
$cleanurl=Url($pageName);
echo $cleanurl;

Answer 6

This is a situation where I would just use a regular expression. Here's the code:

$pagename = basename("http://www.myurl.com/index.php?lang=en");

$pagename = preg_replace("/\..*/", "", $pagename);

You can see a working demo here: https://ideone.com/RdrHzc

The first argument is an expression that matches for a literal period followed by any number of characters. The second argument tells the function to replace the matched string with an empty string, and the last argument is the variable to operate on.
