What is the purpose of using reset() function on an array in PHP?

The reset() function in PHP is used to move the internal pointer of an array to the first element. This can be useful when you want to iterate over an array from the beginning or if you want to perform operations on the first element specifically.

$array = [1, 2, 3, 4, 5];
reset($array); // moves the internal pointer to the first element

// Now you can access the first element of the array
echo current($array); // outputs 1
