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

설명

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.

Note: Sandbox 지원(runkit_linux(), runkit_lint_file(), Runkit_Sandbox 클래스에 필요합니다)은 PHP 5.1이나 특별히 패치된 PHP 5.0에서 쓰레드 안전(therad safety)을 활성화해야 합니다. 자세한 정보는 runkit 패키지에 포함된 README 파일을 참고하십시오.

Note: 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.

인수

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.

반환값

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