Sets the handler called when a server message is raised
bool sybase_set_message_handler ( callable $handler [, resource $link_identifier ] )

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.

Parameters:
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.

link_identifier

If the link identifier isn't specified, the last opened link is assumed.

Returns:

Returns TRUE on success or FALSE on failure.

Notes:
This function is only available when using the CT library interface to Sybase, and not with the DB library.
