This is superior to the serializing/embedding technique, which some of the commenters to this post, have shown.

Why won't people accept this is just an issue with PHP and there's no semantic fix for it? Functions aren't first-class objects like in languages such as Python. After living with Python for a year I have no love for PHP, but that being said I still think there's no reason to try and make it something it isn't. If I can't do <code>$var = fn</code> then why bother? The kludgy workarounds aren't worth it. PHP isn't a Functional language. Heck, it's hardly Object-Oriented (at least before the latest 5 release). Why try to make it that way? If you want functional, if you want proper OO, use a better language. Just my 2 cents. Bah.

My intention with this post, was not to dwell too much about implementation. The point is, that it's impractical to use, for performance reasons. Paul Meagher:

These are your main tools for doing functional programming in PHP. List comprehension is another feature that is often mentioned in the context of functional programming. Haskell blows most other languages out of the water in terms of its implementation of this feature. Hope you keep the functional programming tread alive in a few more posts.... would be nice to see PHP influenced more by functional programming languages rather than predominately OO langs like Java.

"), \$args); return call_user_func_array(\"$func\", \$args);"); } The curry example function could be written quite easily with create_function:

function curry($func, $args) {
if (!is_array($args) ) {
$args = array($args);
}
return create_function(”", “\$args = func_get_args(); \$args = array_merge(array(” . implode(”\”,\”", $args) . “), \$args); return call_user_func_array(\”$func\”, \$args);”);
