runkit_sandbox_output_handler()

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

Syntax

mixed runkit_sandbox_output_handler (object $sandbox, mixed $callback)

Arguments

• 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.

Description

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.

Version

PHP PECL runkit >= 0.7.0

Return value

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