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 Descriptionbool 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.
Note: This function is only available using
the CT library interface to Sybase, and not the DB library.
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.
Returns TRUE on success or FALSE on failure.
Note:
The connection parameter was added in
PHP 4.3.5.
Example 1. sybase_set_message_handler() callback function
<?php
function msg_handler($msgnumber, $severity, $state, $line, $text)
{
var_dump($msgnumber, $severity, $state, $line, $text);
}
sybase_set_message_handler('msg_handler');
?>

Example 2. sybase_set_message_handler() callback to a class
<?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'));
?>

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');
?>
