To remove elements from a PHP array, you can use the unset() function or array_splice() function, depending on your requirements.

  1. Using unset(): This function is used to unset a specified variable or element from an array.


Here is an example to remove a specific element by its key:

1
2
$array = array("apple", "banana", "orange", "grape");
unset($array[1]); // removes "banana" from the array


  1. Using array_splice(): This function is used to remove a portion of an array and replace it with something else.


Here is an example to remove a specific element by its index:

1
2
$array = array("apple", "banana", "orange", "grape");
array_splice($array, 1, 1); // removes the element at index 1 ("banana") from the array


Both methods will modify the original array. The unset() method can remove a single element or multiple elements at once, while array_splice() can remove a portion of an array. Choose the method that suits your specific needs.
