    Basic usage for LuaSandbox

    Once you've compiled PHP with LuaSandbox support, you can begin using LuaSandbox to safely run user-provided Lua code.

    例1 Execute some Lua code

    <?php

    $sandbox     = new LuaSandbox;
    $sandbox->setMemoryLimit( 50 * 1024 * 1024 );
    $sandbox->setCPULimit( 10 );

    // Register some functions in the Lua environment

    function frobnosticate( $v ) {
    return [     $v + 42 ];
    }

    $sandbox->registerLibrary( 'php', [
    'frobnosticate' => 'frobnosticate',
    'output' => function ( $string ) {
    echo     "$string\n";
    },
    'error' => function () {
    throw new     LuaSandboxRuntimeError( "Something is wrong" );
    }
    ] );

    // Execute some Lua code, including callbacks into PHP and into Lua

    $luaCode = <<<EOF
    php.output( "Hello, world" );

    return "Hi", function ( v )
    return php.frobnosticate( v + 200 )
    end
    EOF;

    list(     $hi, $frob ) = $sandbox->loadString( $luaCode )->call();
    assert( $frob->call( 4000 ) === [ 4242 ] );

    // PHP-thrown LuaSandboxRuntimeError exceptions can be caught inside Lua

    list( $ok, $message ) = $sandbox->loadString( 'return pcall( php.error )' )->call();
    assert( !$ok );
    assert( $message === 'Something is wrong' );

    ?>
