title: Solution for "Fatal error: Maximum function nesting level of '100' reached, aborting!" in PHP
body: <p>I have made a function that finds all the URLs within an html file and repeats the same process for each html content linked to the discovered URLs. The function is recursive and can go on endlessly. However, I have put a limit on the recursion by setting a global variable which causes the recursion to stop after 100 recursions.</p>
  <p>However, php returns this error:</p>
  <blockquote>
  <p>Fatal error: Maximum function nesting level of '100' reached,
  aborting! in
  D:\wamp\www\crawler1\simplehtmldom_1_5\simple_html_dom.php on line
  1355</p>

  <p>I found a solution here: <a href="https://stackoverflow.com/questions/4293775/increasing-nesting-functions-calls-limit">Increasing nesting function calls limit</a> but this is not working in my case.</p>
  <p><em>I am quoting one of the answers from the link mentioned above. Please do consider it.</em></p>
  <blockquote>
  <p>&quot;Do you have Zend, IonCube, or xDebug installed? If so, that is probably where you are getting this error from.</p>
  <p>I ran into this a few years ago, and it ended up being Zend putting that limit there, not PHP. Of course removing it will let &gt;you go past the 100 iterations, but you will eventually hit the memory limits.&quot;</p>

  <p>Is there a way to increase the maximum function nesting level in PHP</p>
