Is SPL implemented in C or php

[kurt.krueckeberg]

I have a C++ background and I now trying to learn PHP. Today I ran
across the SPL classes. How efficient are these classes? Are they
ultimately natively supported by the PHP interpretor, or are they
simply a number of classes entirely implemented in php?

The SPL extension is written in C. You can download the PHP source
tarball and have a look at it.

Just so that I'm certain. Classes such as SplDoublyLinkedList,
SplStack, SplQueue, SplHeap, SplMaxHeap and SplMinHeap are native
types
supported in the PHP interpreter. I grepped on the PHP source code (on
"*.h" and "*.c") for SplDoublyLinkedList and grep didn't find any
hits.

Grep the php_spl_types extension sources.
It is PECL extension, just to notify.
