PSpad doesn't contains all function names from all PHP available libraries. Syntax highlight is based of basic keywords, data types and rules. It's possible there are new keywords or rules applied in new PHP version what PSPad doesn't know. In such case I need some source sample with wrong syntax highlight and description what's wrong. I can update syntax highlighter.
