title: PHP exceptions thrown in error handler are not caught by exception handler
body: <p>I use the following function to set my own error handler and exception handler.</p>
  
  <pre><code>set_error_handler
  set_exception_handler
  </code></pre>
  
  <p>The error handler transforms errors to exception. (throws a new exception)</p>
  
  <p>But these exceptions are not caught by my own exception handler.</p>
  
  <p>error handler example:</p>
  
  <pre><code>function errorHandler($errno, $errstr, $errfile, $errline, $errcontext) {
     throw new Exception("this was an error");
  }
  </code></pre>
  
  <p>exception handler example:</p>
  
  <pre><code>function exceptionHandler($e){
     // don't get here when exception is thrown in error handler
     Logger::logException($e); 
  }
  </code></pre>
  
  <p>(I think this can not work anyway)</p>
  
  <p>Should this work ?</p>
  
  <p>Or can someone explain why it can not work ?</p>
  
  <p>EDIT:</p>
  
  <p>I made some tests, and it should work. </p>
  
  <p>Exceptions thrown in the ErrorHandler are getting caught by the ExceptionHandler 
  And Errors triggered in the ExceptionHandler are getting processed by the ErrorHandler </p>
  
  <p>Just FYI.</p>
  
  <p>My Problem has to be elsewhere</p>
  
  <hr>
  
  <p>EDIT:</p>
  
  <p>I Still have not found why the exception thrown in my errorHandler is not caught by my exceptionHandler.</p>
  
  <p>For Example when I have this somewhere in the code.</p>
  
  <pre><code>trigger_error("this is an error"); // gets handled by the errorHandler
  throw new Exception("this is an exception"); // gets handler by the exceptionHandler
  </code></pre>
  
  <p>The error gets handled by the errorHandler but the exception thrown in the errorHandler gets not handled by the exceptionHandler.</p>
  
  <p>But if I throw an exception at the same place where I trigger an error, this exception gets handled by the exception handler. </p>
  
  <p>(Hope it is somehow understandable what I mean)</p>
  
  <p>I'm clueless here.
  Any Ideas where I have to look for the Problem?</p>
