1. Array_shift () function

Deletes the first element in the array and returns the value of the element. Returns null if the array is empty.
Example:


   
    $test_arr = array (    "name" => "jeanphorn",    "skill" => "programming",    "hobby" => "swimming",);echo array_shift($test_arr). "\n";                                                                                                                                                           print_r($test_arr);?>

Results:

Jeanphorn
Array (
[Skill] = programming
[Hobby] = swimming)

Note: If the key name is numeric, all elements will get a new key name, starting with 0 and incrementing by 1

2. Array_pop () function


Deletes the last element in the array. Returns null if the array is empty.
Example:


   
    $test_arr = array (    "name" => "jeanphorn",    "skill" => "programming",    "hobby" => "swimming",);echo array_pop($test_arr). "\n";                                                                                                                                                           print_r($test_arr);?>

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('
  • '). Text (i)); }; $numbering. FadeIn (1700); }); });
