Dynamic function name in php

Question

I would like to simplify the creation of \"Custom Post Types\" in WordPress as it is tedious to go through the same script and change all the custom post type name instances

Answer 1

Edit (2017-04): Anonymous functions (properly implemented) are the way to go, see answer by David Vielhuber.

This answer is ill advised, as is any approach that involves code as a string, because this invites (among other things) concatenation.

Im not sure if it is advisable to use, or if it helps you, but php allows you to create "anonymous" functions :

function generateFunction ($prefix) {
    $funcname = create_function(
        '/* comma separated args here */', 
        '/* insert code as string here, using $prefix as you please */'
    );
    return $funcname;
}

$func= generateFunction ("news_custom_type_init");
$func(); // runs generated function

I am assuming add_action just calls whatever function you passed.

Note: create_function will not return a function with the name you want, but the contents of the function will be under your control, and the real name of the function is not important.
