PHP combines a two-dimensional array with a field of the same array, a two-dimensional array of arrays _php tutorial

PHP combines a two-dimensional array with the same array of fields, a two-dimensional array of arrays

This example describes how PHP merges the same array of one field in a two-dimensional array. Share to everyone for your reference, as follows:

Example:

Array (3) {[0]=> Array (+) {["id"]=> string (2) "56" ["UID"]=> string (2) "+" ["Euid"]=> string (2) ["Did"]=> string (1) "1" ["Nid"]=> string (1) "0" ["Phonetime"]=> string (Ten) "1443927600" ["Createtime"]=&gt  ; String (Ten) "1443880619" ["Type"]=> string (1) "3" ["Status"]=> string (1) "0" ["Atype"]=> string (1) "1" ["MT Ype "]=> string (1)" 2 "[" Endtime "]=> string (1)" 0 "[" Time "]=> string (10)" October 04 "[" Date "]=> string (6)"  Sunday "[" uname "]=> NULL [" album "]=> string (0)" "} [1]=> Array (+) {[" id "]=> string (2)" "[" UID "]=> String (2) "+" ["Euid"]=> string (2) "1" ["Did"]=> string (1) "1" ["Nid"]=> string (0) "" ["Phonetime"]=&G  T String "1444359600" ["Createtime"]=> string "1444268595" ["Type"]=> string (1) "3" ["Status"]=> stri Ng (1) "0" ["Atype"]=> string (1) "1" ["Mtype"]=> string (1) "2" ["Endtime"]=> string (1) "0" ["Time"]=> s Tring (10) "October 09"[" Date "]=> string (6)" Friday "[" uname "]=> NULL [" album "]=> string (0)" "} [2]=> Array (+) {[" id "]=> String (2) "]=>" ["UID") string (1) "2" ["Euid"]=> string (2) "1" ["Did"]=> string (1) "" ["Nid"]=> str ING (1) "0" ["Phonetime"]=> string (Ten) "1444359620" ["Createtime"]=> string "1444268595" ["Type"]=> stri  Ng (1) "3" ["Status"]=> string (1) "0" ["Atype"]=> string (1) "1" ["Mtype"]=> string (1) "2" ["Endtime"]=> String (1) "0" ["Time"]=> string (10) "October 09" ["Date"]=> string (6) "Friday" ["uname"]=> NULL ["album"]=> s Tring (0) ""}}

The

now wants to merge the elements under this two-dimensional array into the same array as time. The desired effect is:

Array (2) {["October 04"]=> Array (1) {[0]=> Array (+) {["id"]=> string (2) "" "[" UID "]=> string (2)" 14 "[" Euid "]=> string (2)" "" "[" Did "]=> string (1)" 1 "[" Nid "]=> string (1)" 0 "[" Phonetime "]=> St   Ring "1443927600" ["Createtime"]=> string (Ten) "1443880619" ["Type"]=> string (1) "3" ["Status"]=> String (1) "0" ["Atype"]=> string (1) "1" ["Mtype"]=> string (1) "2" ["Endtime"]=> string (1) "0" ["Tim  E "]=> string (10)" October 04 "[" Date "]=> string (6)" Sunday "[" uname "]=> NULL [" album "]=> string (0)"} } ["October 09"]=> Array (2) {[0]=> Array (+) {["id"]=> string (2) "" ["UID"]=> string (2) "[" EU  ID "]=> string (2)" "]=>" ["Did" string (1) "1" ["Nid"]=> string (1) "0" ["Phonetime"]=> string (10) "1444359600" ["Createtime"]=> string (Ten) "1444268595" ["Type"]=> string (1) "3" ["Status"]=> string (1  ) "0" ["Atype"]=> String (1) "1" ["Mtype"]=> string (1) "2" ["Endtime"]=> string (1) "0" ["Time"]=> string (10) "October 09" ["Date"]=> string (6) "Friday" ["uname"]=> NULL ["album"]=> string (0) ""} [1]=> Array (+) {["id"] = = String (2) "" "[" UID "]=> string (1)" 2 "[" Euid "]=> string (2)" 1 "[" Did "]=> string (1)" ["   Nid "]=> string (1)" 0 "[" Phonetime "]=> string (Ten)" 1444359620 "[" Createtime "]=> string (10)" 1444268595 " ["Type"]=> string (1) "3" ["Status"]=> string (1) "0" ["Atype"]=> string (1) "1" ["Mtype"]=> stri Ng (1) "2" ["Endtime"]=> string (1) "0" ["Time"]=> string (10) "October 09" ["Date"]=> string (6) "Friday" ["UN Ame "]=> NULL [" album "]=> string (0)" "}}}

So... The code is simple, not as complex as it is imagined, and the desired result is a three-dimensional array

$result as the original two-dimensional array

$res = Array (); Desired result foreach ($result as $k = = $v) {  $res [$v [' time ']][] = $v;}
