# 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

### Beschreibung

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.

### Parameter-Liste

`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.

`connection`

### Rückgabewerte

Gibt bei Erfolg `TRUE` zurück, im Fehlerfall `FALSE`.

}

sybase_set_message_handler(array($sybase, 'handler'));
?>`

Beispiel #3 sybase_set_message_handler() unhandled messages

`<?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');
?>`
