Get a URL from a HTML src Tag without URL parameters

Question

I have this content in a variable named for example $iframe

$iframe='<iframe title="Example Iframe" width="640" height="360" src="https://example.com/mypage?parameter=1" frameborder="0" allowfullscreen></iframe>';

And I need to strip everything except the src URL without parameters

In the example above something like this should be the final result:

echo $iframe;

https://example.com/mypage

I'm not sure if there is a function to search for properties within a HTML string and then maybe use some regex to strip out the parameters...

Try regexp

/src=\"(.*?)(\?.*\"|\")/

example here. Working php example here

<?php

$re = '/src=\"(.*?)(\?.*\"|\")/';
$str = '\'<iframe title="Example Iframe" width="640" height="360" src="https://example.com/mypage?parameter=1" frameborder="0" allowfullscreen></iframe>\'';

preg_match_all($re, $str, $matches, PREG_SET_ORDER, 0);

// Print the entire match result
var_dump($matches[0][1]);
