php数组拆分、结合

本帖最后由 hongliangjava 于 2013-04-17 10:12:01 编辑 有一个数组：
Array
(
[0] => 15461209
[1] => 12
[2] => 12
[3] => 1055088
[4] => 1
[5] => admin
[6] => 1
[7] => hgtbrshbtyrws
[8] => 1366010391
[9] => hntyrhnrytwsnhbyrtnhb
[10] => 127.0.0.1
[11] => 0
[12] => 0
[13] => 1
[14] => 0
[15] => -1
[16] => -1
[17] => 0
[18] => 0
[19] => 0
[20] => 0
[21] => 0
[22] =>
[23] => 0
[24] => 15461210
[25] => 12
[26] => 12
[27] => 1055088
[28] => 0
[29] => admin
[30] => 1
[31] =>
[32] => 1366075840
[33] => 111111111111111
[34] => 127.0.0.1
[35] => 0
[36] => 0
[37] => 1
[38] => 0
[39] => -1
[40] => -1
[41] => 0
[42] => 0
[43] => 0
[44] => 0
[45] => 0
[46] => 0
[47] => 0
)
想在想变成这种形式：
Array
(
[0] => Array
(
[pid] => 15461209
[fid] => 12
[tid] => 1055088
[first] => 1
[author] => admin
[authorid] => 1
[subject] => hgtbrshbtyrws
[dateline] => 1366010391
[message] => hntyrhnrytwsnhbyrtnhb
[useip] => 127.0.0.1
[invisible] => 0
