The problem is a bit around, dizzy people do not enter ^_^
Array (0 = = Array (' id ' = ' + ', ' title ' = ' A ', ' type ' = ' 1 ', ' bian ' = ' 1 '),
1 = = Array (' id ' = ' + ', ' title ' = ' A ', ' type ' = ' 1 ', ' Bian ' =>2),
2 = = Array (' id ' = ' = ', ' title ' = ' B ', ' type ' = ' 2 ', ' bian ' = ' 1 '),
3 = = Array (' id ' = ' = ', ' title ' = ' C ', ' type ' = ' 2 ', ' bian ' = ' 2 '),
)
When type=1 removes the same ID repetition and key becomes the ID, when type=2 the key becomes the Id_bian form, eventually turns into the following array
Array (0 = = Array (' + ' = ', ' 11_1 ' = ' = ', ' 11_2 ' = ') ')
Then merge with the following array
Array (0 + = array (' Ten ' = ' 1 ', ' 11_2 ' = ' 1 '),
1 = = Array (' Ten ' = ' 1 ', ' 11_2 ' = ' 1 '),
2 = = Array (' 11_1 ' = ' 1 ', ' 11_2 ' = ' 1 '),
3 = = Array (' Ten ' = ' 2 ', ' 11_2 ' = ' 1 '),
)
Eventually get
Array (0 + = array (' + ' = ' 1 ', ' 11_1 ' = ' = ', ' 11_2 ' = ' 1 '),
1 = = Array (' + ' = ' 1 ', ' 11_1 = ', ' 11_2 ' = ' 1 '),
2 = = Array (' ten ' = ' = ', ' 11_1 ' = ' 1 ', ' 11_2 ' = ' 1 '),
3 = = Array (' Ten ' + ' 2 ', ' 11_1 ' = ' = ', ' 11_2 ' = ' 1 '),
)
