php数组拆分、组合
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

[anonymous] => 0
[usesig] => 1
[htmlon] => 0
[bbcodeoff] => -1
[smileyoff] => -1
[parseurloff] => 0
[attachment] => 0
[rate] => 0
[ratetimes] => 0
[status] => 0
[tags] =>
[comment] => 0
)

[1] => Array
(
[pid] => 15461210
[fid] => 12
[tid] => 1055088
[first] => 0
[author] => admin
[authorid] => 1
[subject] =>
[dateline] => 1366075840
[message] => 111111111111111
[useip] => 127.0.0.1
[invisible] => 0
[anonymous] => 0
[usesig] => 1
[htmlon] => 0
[bbcodeoff] => -1
[smileyoff] => -1
[parseurloff] => 0
[attachment] => 0
[rate] => 0
[ratetimes] => 0
[status] => 0
[tags] => 0
[comment] => 0
)

)
写个循环，把想要的数组组合出来，该如何写？考虑性能问题 PHP

[解决办法]

$arr=你的数组..
$key=array (
  0 => 'pid',
  1 => 'fid',
  2 => 'tid',
  3 => 'first',
  4 => 'author',
  5 => 'authorid',
  6 => 'subject',
  7 => 'dateline',
  8 => 'message',
  9 => 'useip',
  10 => 'invisible',
  11 => 'anonymous',
  12 => 'usesig',
  13 => 'htmlon',
  14 => 'bbcodeoff',
  15 => 'smileyoff',
  16 => 'parseurloff',
  17 => 'attachment',
  18 => 'rate',
  19 => 'ratetimes',
  20 => 'status',
  21 => 'tags',
  22 => 'comment',
);

foreach(array_chunk($arr,24) as $v){
     array_splice($v,1,1);
     $ar[]=array_combine($key,$v);
}
print_r($ar);
