Re: Suggestion to zend-api: some lookahead could make functions calls faster!

hi, just an idea: if a c-function knew the the returned value will be discarded by the caller (the script) there would be no need to set up return_value. reset() for example returns a copy of the 1st array element. i never use that... reset($arr); // no need to copy 1st array element into return_value $first = reset($arr); // set up return_value

This sounds like a pretty good idea. I'll try and take the time to implement this.

even smarter libzend could pass a flag to a c-function telling that the return-value will just be used as a bool: $a = key($array); // key() needs to create the return_value completely if (key($array)) // resturn_value could just be true/false { }

Forget it :)

i'd also like a new set of first(), current(), next() etc functions that return a reference to the corresponding array element instead of a copy - something like r_first() would be ugly - how about &first()?

You can't use &first as a function name. I don't like the first(), current(), next() syntax (it only exists for PHP/FI 2 compatibility). I think having something like each() or foreach() that works with references is more feasible. Andi --- Andi Gutmans <andi@zend.com> http://www.zend.com/
