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() 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' ); ?> |
