runkit_sandbox_output_handler

(PECL runkit >= 0.7.0)

runkit_sandbox_output_handler — Specify a function to capture and/or process output from a runkit sandbox

Opis

mixed runkit_sandbox_output_handler ( object $sandbox [, mixed $callback ] )

Ordinarily, anything output (such as with echo or print) will be output as though it were printed from the parent's scope. Using runkit_sandbox_output_handler() however, output generated by the sandbox (including errors), can be captured by a function outside of the sandbox.

Informacja: Obsługa rozszerzenia Sandbox (wymagane dla runkit_lint(), runkit_lint_file(), i klasy Runkit_Sandbox) jest dostępna tylko w PHP 5.1.0 lub specjalnie zmodyfikowanych wersjach PHP 5.0, i wymaga włączonego bezpieczeństwa wątków. Więcej informacji można znaleźć w pliku README dołączonym do pakietu runkit.

Informacja: Deprecated

As of runkit version 0.5, this function is deprecated and is scheduled to be removed from the package prior to a 1.0 release. The output handler for a given Runkit_Sandbox instance may be read/set using the array offset syntax shown on the Runkit_Sandbox class definition page.

Parametry

sandbox: Object instance of Runkit_Sandbox class on which to set output handling.
callback: Name of a function which expects one parameter. Output generated by sandbox will be passed to this callback. Anything returned by the callback will be displayed normally. If this parameter is not passed then output handling will not be changed. If a non-truth value is passed, output handling will be disabled and will revert to direct display.

Zwracane wartości

Returns the name of the previously defined output handler callback, or FALSE if no handler was previously defined.
