sybase_set_message_handler — Sets the handler called when a server message is raised
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.
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_identifierIf the link identifier isn't specified, the last opened link is assumed.
Returns TRUE on success or FALSE on failure.

Example #2 sybase_set_message_handler() callback to a class
<?php
class Sybase {
function handler($msgnumber, $severity, $state, $line, $text)
{

}
}
$sybase= new Sybase();
sybase_set_message_handler(array($sybase, 'handler'));
?>
Example #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');
?>
