Using unset() Function:

PHP unset() removes a specified element from an array.

$array = ["element1", "element2", "element3"]; 
// Initialize an array
unset($array[1]); 
// Remove the element at index 1 ("element2")

Using array_pop() Function:

PHP array_pop() removes and returns the last element of an array.

$array = ["element1", "element2", "element3"]; // Initialize an array
$lastElement = array_pop($array); 
// Remove and return the last element ("element3")

Using array_shift() Function:

PHP array_shift() removes and returns the first element of an array, shifting all other elements to a lower index.

$array = ["element1", "element2", "element3"]; 
// Initialize an array
$firstElement = array_shift($array); 
// Remove and return the first element ("element1")
