sybase_set_message_handler
(PHP 4 >= 4.3.0)
sybase_set_message_handler -- Sets the handler called when a server message is raised
Description
bool
sybase_set_message_handler ( callback handler)
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');
?> |
