note 114924 modified in function.count by cmb

[Editor's note: array at from dot pl had pointed out that count() is a cheap operation; however, there's still the function call overhead.] If you want to run through large arrays don't use count() function in the loops , its a over head in performance, copy the count() value into a variable and use that value in loops for a better performance. Eg: // Bad approach for($i=0;$i<count($some_arr);$i++) { // calculations } // Good approach $arr_length = count($some_arr); for($i=0;$i<$arr_length;$i++) { // calculations } --was-- If you want to run through large arrays don't use count() function in the loops , its a over head in performance, copy the count() value into a variable and use that value in loops for a better performance.
