I am proud to announce the 0.9.12 release of PHP_Depend. PHP_Depend is a low level static code analysis tool. It takes the given source and calculates several software metrics for the code. This data can be used by software-developers, architects and designers to control the quality of a software-product without time consuming code audits.

This new release of PHP_Depend has done a great step into the direction of a token free PHP_Depend version. This means future versions of PHP_Depend will work without the need to traverse linear token streams up and down, to measure metrics. Instead PHP_Depend will rely on it's internal abstract syntax tree, that represents the logical structure of the analyzed source code. With this solution it will be possible to implement several new features that will make PHP_Depend more useful, for example static callgraph analysis.

• Implemented #97: Replace current token approach in CCN- and NPath-Analyzer with AST-Nodes. Implemented in svn revision #1248.
• Implemented #125: PHP_Depend silently parses list statements. Fixed in svn revision #1223. Thanks to Joey Mazzarelli for providing this patch.
• Implemented #126: Generate reproducable node identifiers instead of random numbers. Implemented in svn revision #1244.
• Fixed #128: Variable variables in foreach statement cause an exception. Fixed in svn revision #1237.
• Fixed #133: Fatal error: Maximum function nesting level of '100' reached, aborting! in /usr/share/pear/PHP/Depend/Util/Log.php on line 109. Fixed in svn revision #1257.
• Fixed #134: ASTReturnStatement is not derived from ASTStatement. Fixed in svn revision #1250.
• Fixed #135: Several Statement classes do not inherit ASTStatement. Fixed in svn revision #1255.
