Sets the handler called when a server message is raised
bool sybase_set_message_handler ( callable $handler [, resource $link_identifier ] )
sybase_set_message_handler() sets a user function to handle messages generated by the server. You may specify the name of a global function, or use an array to specify an object reference and a method name.
Parameters:
handler
The handler expects five arguments in the following order: message number, severity, state, line number and description. The first four are integers. The last is a string. If the function returns FALSE, PHP generates an ordinary error message.
link_identifier
If the link identifier isn't specified, the last opened link is assumed.
Returns:
Returns TRUE on success or FALSE on failure.
Notes:
This function is only available when using the CT library interface to Sybase, and not with the DB library.
Examples:
sybase_set_message_handler() callback function
1 2 3 4 5 6 7 8 | <?php function msg_handler($msgnumber, $severity, $state, $line, $text) { var_dump($msgnumber, $severity, $state, $line, $text); } sybase_set_message_handler('msg_handler');?> |
sybase_set_message_handler() callback to a class
1 2 3 4 5 6 7 8 9 10 11 | <?php class Sybase { function handler($msgnumber, $severity, $state, $line, $text) { var_dump($msgnumber, $severity, $state, $line, $text); } } $sybase= new Sybase(); sybase_set_message_handler(array($sybase, 'handler'));?> |
sybase_set_message_handler() unhandled messages
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | <?php // Return FALSE from this function to indicate you can't handle // this. The error is printed out as a warning, the way you're used // to it if there is no handler installed. function msg_handler($msgnumber, $severity, $state, $line, $text) { if (257 == $msgnumber) { return false; } var_dump($msgnumber, $severity, $state, $line, $text); } sybase_set_message_handler('msg_handler');?> |
