sybase_set_message_handler

Description

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.

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.

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Пример 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'); ?>

Пример 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')); ?>

Пример 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'); ?>
