Right now, the zend_function struct contains a char *function_name but no
int function_name_len. In light of the comments below, I think this is a
bug, or a bug waiting to happen.

No code in PHP should assume this. PHP should always check the le
If the string functions (str*()) don't work with function names in PHP,
it's all for the better. Code that works with these function names should
only be using mem*() functions anyway, they're quicker and they're binary safe.

Actually, any code in PHP can assume this. Any zval coming from the engine
is NULL terminated, so zval.str.val[zval.str.len] is always
NULL. Obviously, if you create the string, you have to NULL terminate it
before you can assume that :)
If a string is not NULL terminated, it is a bug.
