// This makes use of the PHP module loader provided via V8Js::setModuleLoader (see PHP API above).
require("path/to/module");
The JavaScript `in` operator, when applied to a wrapped PHP object,
works the same as the PHP `isset()` function. Similarly, when applied
to a wrapped PHP object, JavaScript `delete` works like PHP `unset`.
```php
<?php
class Foo {
var $bar = null;
}
$v8 = new V8Js();
$v8->foo = new Foo;
// This prints "no"
$v8->executeString('print( "bar" in PHP.foo ? "yes" : "no" );');
?>
```
PHP has separate namespaces for properties and methods, while JavaScript
has just one. Usually this isn't an issue, but if you need to you can use
a leading `$` to specify a property, or `__call` to specifically invoke a
method.
```php
<?php
class Foo {
var $bar = "bar";
function bar($what) { echo "I'm a ", $what, "!\n"; }
}
$foo = new Foo;
// This prints 'bar'
echo $foo->bar, "\n";
// This prints "I'm a function!"
$foo->bar("function");
$v8 = new V8Js();
$v8->foo = new Foo;
// This prints 'bar'
$v8->executeString('print(PHP.foo.$bar, "\n");');
// This prints "I'm a function!"
$v8->executeString('PHP.foo.__call("bar", ["function"]);');
?>
```
