each() php

The each() function in PHP is used to fetch the key-value pair from an array and move the internal pointer of the array forward. It returns the current key-value pair and moves the pointer to the next pair.

Here is the syntax of the each() function:

each(array $array): array|false

Parameters:

• $array: The input array.

Return Value:

• An array containing the current key-value pair from the input array, or false if there are no more elements in the array.

Example:

$fruits = array("apple", "banana", "orange");

$fruit = each($fruits);
print_r($fruit);

Output:

Array
(
    [1] => apple
    [value] => apple
    [0] => 0
    [key] => 0
)

In the above example, the each() function returns the first key-value pair from the $fruits array. The returned array contains the value (apple), the key (0), and their respective indexes (1 and 0).
