EXAMPLES

       Example #1

	      Use set_error_handler(3) to change error messages into ErrorException.

	      <?php
	      function exception_error_handler($severity, $message, $file, $line) {
		  if (!(error_reporting() & $severity)) {
		      // This error code is not included in error_reporting
		      return;
		  }
		  throw new ErrorException($message, 0, $severity, $file, $line);
	      }
	      set_error_handler("exception_error_handler");

	      /* Trigger exception */
	      strpos();
	      ?>

	      The above example will output something similar to:

	      Fatal error: Uncaught exception 'ErrorException' with message 'strpos() expects at least 2 parameters, 0 given' in /home/bjori/tmp/ex.php:12
	      Stack trace:
	      #0 [internal function]: exception_error_handler(2, 'strpos() expect...', '/home/bjori/php...', 12, Array)
	      #1 /home/bjori/php/cleandocs/test.php(12): strpos()
	      #2 {main}
		thrown in /home/bjori/tmp/ex.php on line 12
