Combined use of list () and each () function in PHP

The parameter of each () function is an array, the return value is an array, for example, the parameter is an array $arr1, the pointer just starts at the initial position of the array, the first returned array is the first key value pair in the parameter array, the returned array has four keys, "0" and "key" are the first key of the parameter array, [1 Value] is the first value of the parameter array, the argument after the list () function should be an array of numbers, so the accepted array can only be an array of keys [0] and [1] in each return, then assign a value to the parameter in list (), assign the value of [0] to the first argument, and the key to [1] Value is assigned to the second parameter.

Example $arr = Array (user=>chen,pwd=> "123");

while (list ($name, $value) = each ($arr)) {

echo $name. " = ". $value;

}

The last thing you get is user = Chen.

PWD = 123
