sybase_set_message_handler — Sets the handler called when a server message is raised
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.
If the link identifier isn't specified, the last opened link is assumed.
Returns TRUE on success or FALSE on failure.
Version | Description |
---|---|
4.3.5 | The link_identifier parameter was added. |
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');
?>
Note: This function is only available when using the CT library interface to Sybase, and not with the DB library.
