How can the "remove" function be effectively integrated into the existing PHP code to handle deletion of specific elements?

To integrate the "remove" function into existing PHP code to handle deletion of specific elements, you can create a function that takes the element to be removed as a parameter and then use array functions like array_search and unset to remove the element from the array.

function removeElement($array, $element) {
    $index = array_search($element, $array);
    if ($index !== false) {
        unset($array[$index]);
    }
    return $array;
}

// Example of how to use the removeElement function
$array = [1, 2, 3, 4, 5];
$elementToRemove = 3;
$array = removeElement($array, $elementToRemove);
print_r($array);
