title: PHP preg_match_all fails with 2 arguments
body: <p>i've got the variable $randomWiki with the following String : </p>
  
  <pre><code>[...]"wgNamespaceNumber":0,"wgPageName":"Busfahrer","wgTitle":"Busfahrer","wgCurRevisionId"[...]
  </code></pre>
  
  <p>And want to get the "wgTitle" out of it. 
  I built the following regex:</p>
  
  <pre><code>preg_match_all("/\"wgTitle\":\"(.*?)\"/", $randomWiki);
  </code></pre>
  
  <p>var_dump is giving me bool(false). 
  I've already checked the regex with an online tool and it worked. </p>
  
  <p>Any Suggestions?</p>
