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.

Замечание: Эта функция доступна только при использовании интерфейса к Sybase библиотеки CT, но не библиотеки DB.

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.

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Замечание: The connection parameter was added in PHP 4.3.5.
