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

Descripción

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.

Parámetros

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.

Valores devueltos

Devuelve TRUE en caso de éxito o FALSE en caso de error.
