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');
	      ?>

SET_EXCEPTION_HANDLER(3)						 1						  SET_EXCEPTION_HANDLER(3)

set_exception_handler - Sets a user-defined exception handler function

SYNOPSIS

       callable set_exception_handler (callable  $exception_handler)

DESCRIPTION

	Sets  the  default exception handler if an exception is not caught within a try/catch block. Execution will stop after the $exception_han-
       dler is called.

PARAMETERS

	      o $exception_handler
		- Name of the function to be called when an uncaught exception occurs. This handler function needs to accept one parameter,  which
		will be the exception object that was thrown. This is the handler signature:
		void handler (Exception  $ex) NULL may be passed instead, to reset this handler to its default state.

	      Caution

		      Note  that  providing  an  explicit  Exception  type  hint for the $ex parameter in your callback will cause issues with the
		     changed exception hierarchy in PHP 7.

RETURN VALUES

	Returns the name of the previously defined exception handler, or NULL on error. If no previous handler was defined, NULL is also returned.
