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. The sample code is as follows:
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.
The sample 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.
