SYBASE_SET_MESSAGE_HANDLER(3)											     SYBASE_SET_MESSAGE_HANDLER(3)

sybase_set_message_handler - Sets the handler called when a server message is raised

SYNOPSIS

       bool sybase_set_message_handler (callable  $handler, [resource  $link_identifier])

DESCRIPTION

       sybase_set_message_handler(3)  sets  a user function to handle messages generated by the server. You may specify the name of a global func-
       tion, or use an array to specify an object reference and a method name.

PARAMETERS

	      o $handler
		- The handler expects five arguments in the following order: message number, severity, state, line  number  and  description.  The
		first four are integers. The last is a string. If the function returns FALSE, PHP generates an ordinary error message.

	      o $link_identifier
		- If the link identifier isn't specified, the last opened link is assumed.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      sybase_set_message_handler(3) callback function

	      <?php
		  function msg_handler($msgnumber, $severity, $state, $line, $text)
		  {
		      var_dump($msgnumber, $severity, $state, $line, $text);
		  }

		  sybase_set_message_handler('msg_handler');
	      ?>

       Example #2

	      sybase_set_message_handler(3) callback to a class

	      <?php
		  class Sybase {
		      function handler($msgnumber, $severity, $state, $line, $text)
		      {
			  var_dump($msgnumber, $severity, $state, $line, $text);
		      }
		  }

		  $sybase= new Sybase();
		  sybase_set_message_handler(array($sybase, 'handler'));
	      ?>

       Example #3

	      sybase_set_message_handler(3) unhandled messages

	      <?php
		  // Return FALSE from this function to indicate you can't handle
		  // this. The error is printed out as a warning, the way you're used
		  // to it if there is no handler installed.
		  function msg_handler($msgnumber, $severity, $state, $line, $text)
		  {
		      if (257 == $msgnumber) {
			  return false;
		      }
		      var_dump($msgnumber, $severity, $state, $line, $text);
		  }

		  sybase_set_message_handler('msg_handler');
	      ?>

RUNKIT_SANDBOX_OUTPUT_HANDLER(3)					 1					  RUNKIT_SANDBOX_OUTPUT_HANDLER(3)

runkit_sandbox_output_handler - Specify a function to capture and/or process output from a runkit sandbox

SYNOPSIS

       mixed runkit_sandbox_output_handler (object  $sandbox, [mixed  $callback])

DESCRIPTION

	Ordinarily,  anything  output  (such  as with echo(3) or print(3)) will be output as though it were printed from the parent's scope. Using
       runkit_sandbox_output_handler(3) however, output generated by the sandbox (including errors), can be captured by a function outside of  the
       sandbox.

       Note

	      Sandbox  support	(required for runkit_lint(3), runkit_lint_file(3), and the Runkit_Sandbox class) is only available as of PHP 5.1.0
	      or specially patched versions of PHP 5.0, and requires that thread safety be enabled. See the README file  included  in  the  runkit
	      package for more information.

       Note

	      Deprecated

	       As  of  runkit version 0.5, this function is deprecated and is scheduled to be removed from the package prior to a 1.0 release. The
	      output handler for a given Runkit_Sandbox instance may be read/set using the array offset syntax shown on the  Runkit_Sandbox  class
	      definition page.

PARAMETERS

	      o $sandbox
		- Object instance of Runkit_Sandbox class on which to set output handling.

	      o $callback
		-  Name of a function which expects one parameter. Output generated by $sandbox will be passed to this callback. Anything returned
		by the callback will be displayed normally. If this parameter is not passed then output handling will not be changed.  If  a  non-
		truth value is passed, output handling will be disabled and will revert to direct display.

RETURN VALUES

	Returns the name of the previously defined output handler callback, or FALSE if no handler was previously defined.

EXAMPLES

       Example #1

	      Feeding output to a variable

	      <?php
	      function capture_output($str) {
		$GLOBALS['sandbox_output'] .= $str;

		return '';
	      }

	      $sandbox_output = '';

	      $php = new Runkit_Sandbox();
	      runkit_sandbox_output_handler($php, 'capture_output');
	      $php->echo("Hello
");
	      $php->eval('var_dump("Excuse me");');
	      $php->die("I lost myself.");
	      unset($php);

	      echo "Sandbox Complete

";
	      echo $sandbox_output;
	      ?>

	      The above example will output:

	      Sandbox Complete

	      Hello
	      string(9) "Excuse me"
	      I lost myself.
