把array的默认键改成指定的字符串

dump($array);

array(2) {
  [0] => array(6) {
    [0] => string(1) "1"
    [1] => string(10) "1470650276"
    [2] => string(12) "测试人员"
    [3] => string(9) "vpn出售"
    [4] => string(20) "出售10个包月VPN"
    [5] => string(6) "100000"
  }
  [1] => array(6) {
    [0] => string(1) "2"
    [1] => string(10) "1470650739"
    [2] => string(12) "测试人员"
    [3] => string(9) "服务器"
    [4] => string(28) "双核CPU2G内存40SDD硬盘"
    [5] => string(5) "15000"
  }
}

我想改成这样

array(2) {
  [0] => array(6) {
    ["record_id"] => string(1) "1"
    ["record_create_time"] => string(10) "1470650276"
    ["record_create_people"] => string(12) "测试人员"
    ["record_name"] => string(9) "vpn出售"
    ["record_comment"] => string(20) "出售10个包月VPN"
    ["record_money"] => string(6) "100000"
  }
  [1] => array(6) {
    ["record_id"] => string(1) "2"
    ["record_create_time"] => string(10) "1470650739"
    ["record_create_people"] => string(12) "测试人员"
    ["record_name"] => string(9) "服务器"
    ["record_comment"] => string(28) "双核CPU2G内存40SDD硬盘"
    ["record_money"] => string(5) "15000"
  }
}

回复内容：

dump($array);

array(2) {
  [0] => array(6) {
    [0] => string(1) "1"
    [1] => string(10) "1470650276"
    [2] => string(12) "测试人员"
    [3] => string(9) "vpn出售"
    [4] => string(20) "出售10个包月VPN"
    [5] => string(6) "100000"
  }
  [1] => array(6) {
    [0] => string(1) "2"
    [1] => string(10) "1470650739"
    [2] => string(12) "测试人员"
    [3] => string(9) "服务器"
    [4] => string(28) "双核CPU2G内存40SDD硬盘"
    [5] => string(5) "15000"
  }
}

我想改成这样

array(2) {
  [0] => array(6) {
    ["record_id"] => string(1) "1"
    ["record_create_time"] => string(10) "1470650276"
    ["record_create_people"] => string(12) "测试人员"
    ["record_name"] => string(9) "vpn出售"
    ["record_comment"] => string(20) "出售10个包月VPN"
    ["record_money"] => string(6) "100000"
  }
  [1] => array(6) {
    ["record_id"] => string(1) "2"
    ["record_create_time"] => string(10) "1470650739"
    ["record_create_people"] => string(12) "测试人员"
    ["record_name"] => string(9) "服务器"
    ["record_comment"] => string(28) "双核CPU2G内存40SDD硬盘"
    ["record_money"] => string(5) "15000"
  }
}

$keys = array('record_id', 'record_create_time', 'record_create_people', 'record_name', 'record_comment', 'record_money');
foreach ($array as $i=>$vals) {
    $array[$i] = array_combine($keys, $vals);
}
var_dump($array);

可以看一下手册中数组操作的函数
