如何設置數組中的值索引

Question

Array 
(
    [a31df20a1e75a9200fc0d8b136438c91] => Array 
     (
      [addons] => Array 
       (
        [0] => Array 
         (
          [name] => Add Message here, First 5 Words Free 
          [value] => tyyty tytyt ty 
          [price] => 10 
         ) 

       ) 

      [product_id] => 1356 
      [variation_id] => 
      [variation] => 
      [quantity] => 1 
      [line_total] => 110 
      [line_tax] => 0 
      [line_subtotal] => 110 
      [line_subtotal_tax] => 0 
     ) 

) 

如何設置「[line_total] => 110」的值？

Answer 1

$thearray['a31df20a1e75a9200fc0d8b136438c91']['line_total'] = 110; 

Answer 2

你知道路徑的值，所以你可以把它..

$array['a31df20a1e75a9200fc0d8b136438c91']['line_total'] = 12345;
