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.

Returns TRUE on success or FALSE on failure.

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'); ?>
