TalkPHP - View Single Post - some problem in array_search and the use of unset

PHP doesn't use exceptions as general error handling, however using the builtin ErrorException class you can turn that into reality, but only if PHP emits an error:

php Code:

<?php
/* This is the call back for set_error_handler */
function exception_error_handler($severity, $message, $file, $line )
{
    throw new ErrorException($message, 0, $severity, $file, $line);
}

/* Set the new error handler */
set_error_handler('exception_error_handler');

/* Trigger exception, because this function needs more than 0 parameters */
try
{
    min();
}
catch(ErrorException $e)
{
    switch($e->getSeverity())
    {
        case(E_WARNING):
        {
            printf('Warning: %s in %s on line %d', $e->getMessage(), $e->getFile(), $e->getLine());
        }
        break;
        /* ... same for other error levels thats catchable here ... */
    }
}
?>

and testing:

Code:

C:\> php test.php
Warning: min() expects at least 1 parameter, 0 given in C:\test.php on line 14
