PHPTALES is the equivalent of TALES, the Template Attribute Language Expression Syntax which is the syntax used inside TAL, METAL, PHPTAL attributes and ${…} inline expressions.
In previous examples, you should have seen some PHPTALES examples (string:, php:, not:, …). This chapter describes the usage of PHPTALES in templates.
The value of a TAL attribute may contain more than one expression (ex: tal:define), in which case each expression must be separated from the next one with a ';' character.
