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.
