title: How to set Stack trace depth of PHP's error log?
body: <p>In my <code>php.ini</code> I set this line:</p>
  
  <pre><code>error_log = c:/php/php_errors.log
  </code></pre>
  
  <p>It enables output of errors into the specified file.</p>
  
  <p>However, it always outputs maximum of 4, i.e.:</p>
  
  <pre><code>PHP Fatal error:  Uncaught ServiceNotFoundException
  Stack trace:
  #0 PluginManager.php(124): AbstractPluginManager-&gt;get('getEntityManage...', NULL)
  #1 AbstractController.php(301): PluginManager-&gt;get('getEntityManage...', NULL)
  #2 AbstractController.php(316): AbstractController-&gt;plugin('getEntityManage...')
  #3 AbstractPluginManager.php on line 133
  ^^^ stops at depth 4 always
  </code></pre>
  
  <p>I want to control the stack depth.  How?
  I could not find anything on <a href="http://php.net/error-log" rel="noreferrer">http://php.net/error-log</a></p>
