The PhpTags extension implements the concept of Magic expressions with PHP language syntax that allows you to create and use compatible but not monolithic MediaWiki extensions, which greatly increases the convenience, flexibility and performance. More ...


The PhpTags extension has its own the runtime environment PHP code which supports scalar types, arrays, variables, operators, control structures. It also supports constants, functions and objects but it does not implement any of them except for some language constructs.

When using a function, object or constant PhpTags calls corresponding extension. Therefore, a set of constants, functions, objects and actions that they produce only depend on additionally installed compatible extensions which can be found here.

PhpTags designed so to be as similar to native PHP, therefore you should have the illusion of direct execution PHP code although this never happens.


The code should be placed between the tags ‎<phptag> and ‎</phptag>. It can be located in any namespace if it is allowed by the variable $wgPhpTagsNamespaces.

$foo = 'hello world';
echo ucfirst( $foo . "!!!\n" );

Det vil vise:

Hello world!!! 
the function ucfirst is implemented in Extension:PhpTags_Functions . More details can be found in the quick start guide.
