PHP converts a one-dimensional array to a two-dimensional array of 3 consecutive values PHP iterates over two-dimensional arrays PHP defines two-dimensional arrays php two-dimensional array add meta

The example in this paper describes the PHP implementation of converting a one-dimensional array into a two-dimensional array of 3 consecutive values. Share to everyone for your reference, as follows:

<?PHP$AAA = Array (' AA ', ' BB ', ' cc ', ' dd ', ' ee ', ' ff ', ' GG ', ' hh ', ' II '); for ($i =0; $i <3; $i + +) {  $bbb [] = Array_ Slice ($AAA, $i * 3, 3);} Print_r ($BBB);? >

The results of the operation are as follows:

Array (  [0] = = Array    (      [0] = AA      [1] = BB      [2] = + cc    )  [1] = = Array    (      [0] = DD      [1] = EE      [2] = = FF    )  [2] = = Array    (      [0] = = GG      [1] = = Hh
  [2] (= II    ))

Key code:

$bbb [] = Array_slice ($AAA, $i * 3, 3),//3 is 3 groups, if 2 is 2 a group
