The only difference is that zend_hash_find is smart about numeric string indexes. For example, if the array has a key with the integer value 4, doing zend_hash_find after the string key "4" will still find it. zend_hash_quick_find doesn't do this. > Have I missed the docs on these functions somewhere?
