Re: limits on variable/classname length

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_MAX 18446744073709551615UL # else # define ULONG_MAX 4294967295UL # endif On Saturday 25 October 2003 09:36 pm, Greg Beaver wrote: > Hi, > > Are there any limits on the length a variable or classname may be in > PHP?
