Warning

### Description

sybase_set_message_handler ( callable `$handler` [, resource `$link_identifier` ] ) : bool

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.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

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);
