@ -361,6 +361,25 @@ The above rule that PHP objects are generally converted to JavaScript objects al
This behaviour can be changed by enabling the php.ini flag `v8js.use_array_access`. If set, objects of PHP classes that implement the aforementioned interfaces are converted to JavaScript Array-like objects. This is by-index access of this object results in immediate calls to the `offsetGet` or `offsetSet` PHP methods (effectively this is live-binding of JavaScript against the PHP object). Such an Array-esque object also supports calling every attached public method of the PHP object + methods of JavaScript's native Array.prototype methods (as long as they are not overloaded by PHP methods).
Snapshots
=========
First of all snapshots are incompatible with extensions. So when you see
#
# Fatal error in ../src/snapshot/startup-serializer.cc, line 122
# Check failed: !isolate->has_installed_extensions().
#
you need to remove all extension registrations.
Now an simple example on how to use snapshots:
<?php
$snapshot = V8Js::createSnapshot('var fibonacci = n => n < 3 ? 1 : fibonacci(n - 1) + fibonacci(n - 2)');
$jscript = new V8Js('php', array(), array(), true, $snapshot);
echo $jscript->executeString('fibonacci(43)') . "\n";
