How to get the next value of an array and loop it in the array in PHP

Do you know How to get the next value of an array and loop it in the array in PHP ?

To achieve the desired behavior where you want to get the next value from the array given the last value (and wrap around to the first value if the last value is the last element of the array), you can create a PHP function. Here’s a simple implementation for such a function:

function getNextValue(array $values, $lastValue) {
    $lastIndex = array_search($lastValue, $values);
    $nextIndex = ($lastIndex + 1) % count($values);
    return $values[$nextIndex];
}

You can use this function as follows:

$values = [1, 2, 5, 4, 8];
$lastValue = 8;
$nextValue = getNextValue($values, $lastValue);
echo $nextValue; // Output: 1

 

The function takes an array of values and the last value you have. It then finds the index of the last value in the array using array_search. Next, it calculates the index of the next value by adding 1 to the last index and using the modulus (%) operator to ensure that it wraps around to the first index when needed. Finally, it returns the next value based on the calculated index.
