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
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.
