Reorganize the array to merge orders similar to Taobao

{Code...} is similar to the preceding array. You need to combine the same test fields and output them at the front-end. For example, orders of e-commerce websites are merged and online.

Array ('0' => array ('id' => string '22', 'title' => string 'item name ', 'test' => string '000000',) '1' => array ('id' => string '23', 'title' => string 'item name ', 'test' => string '000000',) '2' => array ('id' => string '30', 'title' => string 'item name ', 'test' => string '123 ',))

Similar to the preceding arraytestFields are combined and output at the front-end, similar to orders of e-commerce websites, online, etc.

It is actually very simple:

$ Arra = array ('0' => array ('id' => '22', 'title' => 'item name ', 'test' => '123',), '1' => array ('id' => '23', 'title' => 'item name ', 'test' => '123',), '2' => array ('id' => '30', 'title' => 'item name ', 'test' => '123',); $ result = array (); foreach ($ arra as $ key => $ value) {$ result [$ value ['test'] [] = $ value ;}

The result is a three-dimensional array.
