runkit_sandbox_output_handler
Specify a function to capture and/or process output from a runkit sandbox
&reftitle.description;
mixedrunkit_sandbox_output_handlerobjectsandboxmixedcallback
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.
¬e.runkit.sandbox;
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.
&reftitle.parameters;
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.
&reftitle.returnvalues;
Returns the name of the previously defined output handler callback, or
&false; if no handler was previously defined.
&reftitle.examples;
Feeding output to a variable
echo("Hello\n");
$php->eval('var_dump("Excuse me");');
$php->die("I lost myself.");
unset($php);
echo "Sandbox Complete\n\n";
echo $sandbox_output;
