When you are developing an application some things can goes wrong in your code, for example, a non declared function or class, out of memory and so on.
Even that you are using a test unit, some kind of erros only will occur in production enviroment.
PHP has two function to manipulate error are:
set_error_handler()
and
set_exception_handler()
But, this functions works only in some cenarios, if your code get an E_ERROR or E_PARSE error, you can't catch it.
On the other hand, we can use register_shutdown_function() to catch E_ERROR or E_PARSE error too.
See this piece of code:
<?
/* considering that in production enviroment is recommended don't show errors, it is a default settings in php.ini. */
ini_set('display_errors', 'Off');
register_shutdown_function(create_function('','
if ( ($error = error_get_last()) ) {
// do something what you need, like:
// send email alert about error;
// write/log error to a file;
// show or redirect the user to a customized error page.
echo "Oops, I get a error.<hr/>";
print_r($error);
}
'));
?>
This code is really useful to catch many errors and alert you or developing team about something non expected in you PHP application.
