PHP - How to remove anything after extension (jpg, png, gif, jpeg, svg, ...)

Question

I'm using php 7 and trying to remove anything after extension of urls;

Example

    https://website/sites/tag/filename/IMG25.jpg?iabc=gfds
    to 
    https://website/sites/tag/filename/IMG25.jpg

or

    https://website/sites/tag/filename/IMG25.png&iabc=gfds
    to 
    https://website/sites/tag/filename/IMG25.png

or

    https://website/sites/tag/filename/IMG25.jpeg&abc=gfds
    to 
    https://website/sites/tag/filename/IMG25.jpeg

I'm trying this function

$clean_url = preg_replace(
    "/(.+\.(:?jpg|gif|jp2|png|bmp|jpeg|svg)).*$/",
    '',
    $filename
);

But this function not working

something like "https://website/sites/tag/filename/IMG25.jpg" — Bynd, Apr 28 '19 at 09:44
take a look at `parse_url` https://php.net/manual/en/function.parse-url.php — Professor Abronsius, Apr 28 '19 at 09:48
all solution are for removing what after "?"; my question id removing what after extension not the question mark — Bynd, Apr 28 '19 at 10:04
Duplicate here isn't a real duplicate, since this asker doesn't want to remove query strings specifically. Am voting to reopen. — Mark Amery, Apr 28 '19 at 10:30

I've made some adjustments to your regex in order to capture groups and replace the url by only the first group like this :

$clean_url = preg_replace(
    "/(.+(\.(jpg|gif|jp2|png|bmp|jpeg|svg)))(.*)$/",
    '${1}',
    $url
);

Sample code for all cases :

<?php

$urls = [
    "https://website/sites/tag/filename/IMG25.png&iabc=gfds",
    "https://website/sites/tag/filename/IMG25.jpg?iabc=gfds",
    "https://website/sites/tag/filename/IMG25.jpeg&abc=gfds"
];


foreach ($urls as $url){
    $clean_url = preg_replace(
        "/(.+(\.(jpg|gif|jp2|png|bmp|jpeg|svg)))(.*)$/",
        '${1}',
        $url
    );

    echo $clean_url ."\n";

}

my question is not to remove what after "?" the question mark; my question is how to remove what after extension example .jpg&hg=gfd – Bynd Apr 28 '19 at 10:08
i've noticed that you have a `&` in the second and third examples whereas in the first example you have `?`, does it have to work for both cases ? – Abdelkarim EL AMEL Apr 28 '19 at 10:15
I'm trying to remove anything after extension ? or & or ! ..... example I have a link like mysite/img?id=123&file=image.jpg!gh so I want to remove what is after ".jpg" – Bynd Apr 28 '19 at 10:17

You can do it this way:

First explode your url string using '?' as a delimiter, than use first element of resulted array.

explode('?', $url)[0];
