title: Call to undefined function 'init_set'
body: <p>Does anybody know how to debug <strong>"call to undefined function init_set"</strong> , when trying to change php.ini configuration settings programmatically?  I am just trying to call init_set function in the code, and the apache couldn't process it at that line.</p>
  
  <p>I recently installed my Apache 2.2 on my Windows XP machine, along with php 5.2 as well.</p>
  
  <p>I tried googling and searching stackoverflow for this but I couldn't find the answer I was looking for.</p>
  
  <p>Could anybody shed some light on it?</p>
