LEARN ABOUT PHP
runkit_sandbox_output_handler
RUNKIT_SANDBOX_OUTPUT_HANDLER(3) 1 RUNKIT_SANDBOX_OUTPUT_HANDLER(3)
runkit_sandbox_output_handler - Specify a function to capture and/or process output from a runkit sandbox
SYNOPSIS
mixed runkit_sandbox_output_handler (object $sandbox, [mixed $callback])
DESCRIPTION
Ordinarily, anything output (such as with echo(3) or print(3)) will be output as though it were printed from the parent's scope. Using
runkit_sandbox_output_handler(3) however, output generated by the sandbox (including errors), can be captured by a function outside of the
sandbox.
Note
Sandbox support (required for runkit_lint(3), runkit_lint_file(3), and the Runkit_Sandbox class) is only available as of PHP 5.1.0
or specially patched versions of PHP 5.0, and requires that thread safety be enabled. See the README file included in the runkit
package for more information.
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.
PARAMETERS
o $sandbox
- Object instance of Runkit_Sandbox class on which to set output handling.
o $callback
- Name of a function which expects one parameter. Output generated by $sandbox will be passed to this callback. Anything returned
by the callback will be displayed normally. If this parameter is not passed then output handling will not be changed. If a non-
truth value is passed, output handling will be disabled and will revert to direct display.
RETURN VALUES
Returns the name of the previously defined output handler callback, or FALSE if no handler was previously defined.
EXAMPLES
Example #1
Feeding output to a variable
<?php
function capture_output($str) {
$GLOBALS['sandbox_output'] .= $str;
return '';
}
$sandbox_output = '';
$php = new Runkit_Sandbox();
runkit_sandbox_output_handler($php, 'capture_output');
$php->echo("Hello
");
$php->eval('var_dump("Excuse me");');
$php->die("I lost myself.");
unset($php);
echo "Sandbox Complete
";
echo $sandbox_output;
?>
The above example will output:
Sandbox Complete
Hello
string(9) "Excuse me"
I lost myself.
