Extension:PhpTags

The PhpTags extension enhances parser with magic expressions that has syntax of PHP language. The PhpTags extension supports types, variables, constants, expressions, operators, control structures, functions and objects.

How it works
First the PhpTags compiles the source code into a set of simple commands. Next the Runtime class processes the set of simple commands. The Runtime class performs arithmetic, logical, comparison and assignment operators, conditional execution of code fragments (if statement) and loops. This allows to achieve high performance.

All of constants, functions and objects are a hooks registered by other extensions. When they accessed, PhpTags requests the result from corresponding extension passing it the name of the hook and other required parameters.

Thus achieving the safe use of a scripting language as magic expressions in your wiki. You should have the illusion of direct execution PHP code although this never happens.

Usage
The code should be placed between the tags  and. It can be located in any namespace if it is allowed by the variable.

It will display: Hello world!!!
