Hmmm I _think_ it depends on size_t, which (IIRC) is typically typdef'd as an
unsigned long int. I say that because there are macros (like ZEND_SET_SYMBOL)
that do strlen(name) all over the place. Here's an except from limits.h:
/* Maximum value an `unsigned long int' can hold. (Minimum is 0.) */
# if __WORDSIZE == 64
# define ULONG_MAX18446744073709551615UL
# else
# define ULONG_MAX4294967295UL
# endif

Hi,
Are there any limits on the length a variable or classname may be in
PHP? I was unable to find anything in the manual, and my tests found
that a variable over 2000 characters long still caused no error or
problems.
This is important because phpDocumentor 2.0 will be using a database to
cache parsed data, and I need to know how much space to allocate for the
names of classes and other things.
