Extract string inside multi-quoted variable - php

Question

I've a variable with multiple single quotes and want to extract a string of this.
My Code is:
$image['src'] = addslashes($image['src']);
preg_match('~src=["|\'](.*?)["|\']~', $image['src'], $matches);
$image['src'] = $matches[1];
$image['src'] contains this string:
tooltip_html(this, '<div style="display: block; width: 262px"><img src="https://url.com/var/galerie/15773_262.jpg"/></div>');
I thought all would be right but $image['src'] returns null. The addslashes method works fine and returns this:
tooltip_html(this, \'<div style="display: block; width: 262px"><img src="https://url.com/var/galerie/15773_262.jpg"/></div>\');
I don't get the problem in here, did I miss something?
=====UPDATE======
The whole code:
<?php
error_reporting(E_ALL);
header("Content-Type: application/json", true);
define('SITE', 'https://akipa-autohandel.autrado.de/');

public function addCData($cdata_text) {
$node = dom_import_simplexml($this);
$no = $node->ownerDocument;
$node->appendChild($no->createCDATASection($cdata_text));
}
}

}

$header['errno'] = $err;
$header['errmsg'] = $errmsg;

return $header;
}

if ( $rendering['errno'] != 0 )

Answer 1

The content of $image['src'] is not as you wrote above. I've run now your script and the content is:
tooltip_html(this, '<div style="display: block; width: 262px"><img src="http://server12.autrado.de/autradogalerie_copy/var/galerie/127915_262.jpg" /></div>');
It will work if you add the following line before the preg_match:
$item['src']= html_entity_decode($item['src']);
