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

In php, while (list ($ key, $ val) each ($ result) is used to obtain the array in detail. In php, while (list ($ key, $ val) each ($ result) reads the value of the $ result array and returns the value of the array to $ key and $ val cyclically. For example, the following code copies all the methods in the echo class CAR. in php, while (list ($ key, $ val) = each ($ result )) is to read the $ result array value and obtain the array content cyclically assigned to $ key, $ val.

Example

The code is as follows:
Echo "all methods in the CAR class are named :"; Echo" "; $ 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" "; }

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.

Aggregate (list ($ key, $ val) = each ($ result) is to read the $ result array value and obtain the array content cyclically and assign the value to $ key and $ val. The sample code is as follows: all methods in echo CAR...
