What is the meaning of foreach as in php

The foreach loop is used to traverse the array.

Grammar

Foreach ($array as $value) {to execute code;}

With each loop, the value of the current array element is assigned to the $value variable (the array pointer moves one by one), and on the next loop, you will see the next value in the array.

Foreach ($array as $key = > $value) {to execute code;}

With each loop, the keys and values of the current array elements are assigned to the $key and $value variables (the number pointer moves one by one), and you will see the next key and value in the array on the next loop.

Example
