How to remove an element from an array in PHP?

To remove an element from an array in PHP, you can use the unset() function or the array_splice() function.

Using unset() function:

$myArray = array('element1', 'element2', 'element3', 'element4');

// Remove an element by its index
unset($myArray[1]);

print_r($myArray);

Output:

Array
(
    [0] => element1
    [2] => element3
    [3] => element4
)

Using array_splice() function:

$myArray = array('element1', 'element2', 'element3', 'element4');

// Remove an element by its index
array_splice($myArray, 1, 1);

print_r($myArray);

Output:

Array
(
    [0] => element1
    [1] => element3
    [2] => element4
)

Both methods will remove the element at the specified index from the array. The unset() function directly removes the element, while the array_splice() function can be used to remove multiple elements from an array simultaneously.
