How do I catch a PHP fatal (`E_ERROR`) error?

Question

I can use set_error_handler() to catch most PHP errors, but it doesn\'t work for fatal (E_ERROR) errors, such as calling a function that doesn\'t e

Answer 1

I developed this function to make it possible to "sandbox" code that could cause a fatal error. Since exceptions thrown from the closure register_shutdown_function don't get emitted from the pre-fatal error call stack, I'm forced to exit after this function to provide a uniform way of using it.

function superTryCatchFinallyAndExit( Closure $try, Closure $catch = NULL, Closure $finally )
{
    $finished = FALSE;
    register_shutdown_function( function() use ( &$finished, $catch, $finally ) {
        if( ! $finished ) {
            $finished = TRUE;
            print "EXPLODE!".PHP_EOL;
            if( $catch ) {
                superTryCatchFinallyAndExit( function() use ( $catch ) {
                    $catch( new Exception( "Fatal Error!!!" ) );
                }, NULL, $finally );                
            } else {
                $finally();                
            }
        }
    } );
    try {
        $try();
    } catch( Exception $e ) {
        if( $catch ) {
            try {
                $catch( $e );
            } catch( Exception $e ) {}
        }
    }
    $finished = TRUE;
    $finally();
    exit();
}
