What is the best practice for removing a specific variable from an array in PHP and shifting the subsequent variables accordingly?

When removing a specific variable from an array in PHP, the best practice is to use the array_splice() function. This function allows you to specify the index of the element to be removed and optionally specify the number of elements to remove after that index. By using array_splice(), you can remove the desired variable from the array and shift the subsequent variables accordingly.

// Example array
$array = [1, 2, 3, 4, 5];

// Remove element at index 2 (value 3) from the array
array_splice($array, 2, 1);

// Output the modified array
print_r($array);
