Monitor assignment PHP extension
<p>I'm trying to figure out if it is possible to make an extension that monitors every assignment that is made in PHP. </p>

<p>I want to do some taint detection, I've seen the PHP taint project, but it would be nicer to have it as an extension for my project.</p>

<p>Additionally, where can I find API documentation and similar for Zend/PHP extensions, I haven't been able to find anything good :/</p>
