title: strstr() function in PHP is not working whatsoever
body: <p>I'm running PHP 5.3.8 on my local, 5.2.17 on my remote.</p>
  
  <p>strstr() works fine on my local, but when loaded in remote it returns nothing. Even error reporting doesn't say anything.</p>
  
  <p>A simple use of it:</p>
  
  <pre><code>echo strstr('1234567890', '3', true);
  </code></pre>
  
  <p>should return 12. Instead gives nothing. I'm lost for ideas at this point. How could two identical scripts return different results?</p>
  
  <p>Is it secretly turned off? Or is there a setting I don't know about? Any help much appreciated, thanks.</p>
