Getting Started

A simple way to use, is include in your project rebar.config the following dependency line:

    {ephp, ".*", {git, "git://", master}}

And use the following code in your project:

{ok, Ctx} = ephp:context_new(),
PHP = "<? $a = 5 * 23; ?>Result for $a = <?=$a?>",
{ok, Text} = ephp:eval(Ctx, PHP).

The result stored in Text should be:

Result for $a = 115

Built-in Libs

PHP has a lot of built-in libraries. This interpreter has a little implementation of them. You can see the functions in the compatibility table.

You can add your own functions specifying the PHP name, and the module and function, as follow:

ephp_context:register_func(Ctx, <<"time">>, ephp_func_date, time).
