Question

Is there an easy way to delete an element from an array using PHP, such that foreach ($array) no longer includes that element?

I thought that setting it

Answer 1

"value 1", "key2"=>"value 2", "key3"=>"value 3");

    print_r($my_array);
    if (array_key_exists("key1", $my_array)) {
        unset($my_array['key1']);
        print_r($my_array);
    }
    else {
        echo "Key does not exist";
    }
?>

"value 1", "key2"=>"value 2", "key3"=>"value 3");
    print_r($my_array);
    $new_array = array_slice($my_array, 1);
    print_r($new_array);
?>


    ";
    // To remove first array element to length
    // starts from first and remove two element
    $my_array = array("key1"=>"value 1", "key2"=>"value 2", "key3"=>"value 3");
    print_r($my_array);
    $new_array = array_slice($my_array, 1, 2);
    print_r($new_array);
?>

Output

 Array ( [key1] => value 1 [key2] => value 2 [key3] =>
 value 3 ) Array (    [key2] => value 2 [key3] => value 3 )
 Array ( [key1] => value 1 [key2] => value 2 [key3] => value 3 )
 Array ( [key2] => value 2 [key3] => value 3 )
 Array ( [key1] => value 1 [key2] => value 2 [key3] => value 3 )
 Array ( [key2] => value 2 [key3] => value 3 )
