Php Tutorial list & each instance code
Definition and usage
The each () function generates an array consisting of the key and key values of the elements pointed to by the current internal pointer of the array, and moves the internal pointer forward.

The returned array contains four elements: key name 0, 1, key, and value. Unit 0 and key contain the key name of the array unit, and 1 and value contain data.

If the internal pointer is out of the array range, this function returns false.
