title: PHP: output_buffering ini option is ignored
body: <p>From <code>phpinfo()</code> output:</p>
  
  <pre><code>Loaded Configuration File =&gt; /usr/local/lib/php.ini
  
  output_buffering =&gt; 0 =&gt; 0
  </code></pre>
  
  <p>Inside <code>/usr/local/lib/php.ini</code></p>
  
  <pre><code>output_buffering = 4096
  </code></pre>
  
  <p>Php script results of <code>ini_get('output_buffering')</code> is <code>0</code></p>
  
  <p>I have tried to enable output_buffering at the begining of php script with <code>ini_set('output_buffering',4092)</code>, but it's not helping.</p>
  
  <p>What can cause this behavior?</p>
  
  <p>Thanks ;)</p>
