# sybase_set_message_handler

(PHP 4 >= 4.3.0, PHP 5)

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

## Description

bool sybase_set_message_handler ( callback handler [, resource connection] )

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

> Note: This function is only available using the CT library interface to Sybase, and not the DB library.

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.

Returns `TRUE` on success or `FALSE` on failure.

> Note: The connection parameter was added in PHP 4.3.5.

Example 1. sybase_set_message_handler() 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() 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() 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'); ?>`
