sybase_set_message

Sets a user defined callback function that is called when either a client or a server message is received.

Syntax

bool sybase_set_message_handler(callback $handler, int $msg_type
[, resource $conn])

$handler – the callback handler takes the following arguments:
int – message_number

int – severity

int – state

int – line_number

string – description
$msg_type – one of:
SYB_CLIENTMSG_CB – a client message callback

SYB_SERVERMSG_CB – a server message callback

Note: Although $msg_type is mandatory, currently it is ignored as the installed message handler is called for both client and server messages.
$conn – the connection resource returned by a connection opening function. If the connection resource is not specified, the most recently opened connection is used.

TRUE – callback function installed successfully.

FALSE – failed to install callback function.
