title: PHP language (unit) tests
body: <p>At the moment I am working (just for fun) on a kind of compiler that breaks <code>PHP</code>-code down to a source code for a low level <code>VM</code>.</p>
  
  <p>As the type system and a lot of of the <code>PHP</code>-features are not that logical I need a much testscripts to verify that my code behaves as it would in <code>PHP</code>.</p>
  
  <p>I started to test everything with the test from the <code>PHP</code>-sources (<a href="http://cvs.php.net/viewvc.cgi/php-src/tests/" rel="nofollow noreferrer" title="here">here</a>). But a lot of the test are not only language specific, they also contain some features from the webserver handling (POST-data, etc.) Are there any other tests to test <code>PHP</code> as a language? The best would be, if the script itself is written in <code>PHP</code>.</p>
