(PHP 4 >= 4.3.0)
sybase_set_message_handler -- Sets the handler called when a server message is raisedDescription
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.
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.

{
var_dump($msgnumber, $severity, $state, $line, $text);
}
sybase_set_message_handler('msg_handler');
?>

class Sybase {
function handler($msgnumber, $severity, $state, $line, $text)
{

// this. The error is printed out as a warning, the way you're used
// to it if there is no handler installed.

{
if (257 == $msgnumber) {
