Build Status


Requires at least PHP 5.3.2 but will not properly test trait names until PHP 5.4.0 or later.

It is suggested that you test compatibility with PHP 5.5 or newer in order to use the most up-to-date PHP parser/ tokenizer.


  • Check for deprecated & removed functions (MySQL, mycrypt_*)
  • Check for /e modifier in regular expressions
  • Check for removed Constants (MySQL)
  • Check for setTimeZoneID or datefmt_set_timezone_id usage
  • Check for definitions of global functions which are new in PHP 5.5
  • Check for definitions of classes that have been added in PHP 5.5
  • Check for definitions of constants that have been added in PHP 5.5
