Syntax

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.

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');
