runkit_sandbox_output_handler

(no version information, might be only in CVS)

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

说明

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.

注: 对沙盒的支持（是函数 runkit_lint()、runkit_lint_file() 和 Runkit_Sandbox 类所必须的）仅在 PHP 5.1 中，或在加过特别补丁的 PHP 5.0 中，并需要启用线程安全。请阅读 runkit 包中的 README 文件，以了解更多信息。

参数

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.

返回值

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

例

例子 1. Feeding output to a variable

<?php function capture_output($str) { $GLOBALS['sandbox_output'] .= $str; return ''; } $sandbox_output = ''; $php = new Runkit_Sandbox(); runkit_sandbox_output_handler($php, 'capture_output'); $php->echo("Hello\n"); $php->eval('var_dump("Excuse me");'); $php->die("I lost myself."); unset($php); echo "Sandbox Complete\n\n"; echo $sandbox_output; ?>
上例将输出：
Sandbox Complete Hello string(9) "Excuse me" I lost myself.
