PHP removes an element from an array

   
    $arr = array('aa','bb','cc','dd'); unset($arr[2]); print_r($arr); ?>Array ( [0] => aa[1] => bb [3] => dd)

Unset The biggest drawback is that the array index was not rebuilt and later found to have Array_splice function

   
    functionarray_remove(&$arr, $offset) {    array_splice($arr, $offset, 1); } $arr = array('aa','bb','cc','dd'); array_remove($arr, 2); print_r($arr); ?>Array ( [0] => aa [1] => bb [2] => dd)  

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

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above describes the PHP removal of an element in the array, including the aspects of the content, I hope the PHP tutorial interested in a friend helpful.
