In php, while (list ($ key, $ val) = each ($ result) is used to obtain the array in detail.

In php, while (list ($ key, $ val) = each ($ result) is used to read the $ result array value and obtain the array content cyclically and assign the value to $ key, $ val.

Example

The Code is as follows:	Copy code
Echo "all methods in the CAR class are named :"; Echo "<p> "; $ Result = get_class_methods ("CAR"); // obtain the method name get_class_methods () in the class CAR () While (list ($ key, $ val) = each ($ result) // obtain the array content cyclically { Echo "method $ key => $ val "; Echo "<p> "; }

The list () function assigns values to a group of variables with elements in the array.

Note: Like array (), list () is actually a language structure, not a function.
