我有以下数组：
Array
(
[0] => Array
(
[dest_in_id] => 1
[dest_user_id] => 37251
[dest_inv_user_id] => 37247
[dest_timestamp] => 1387168510
[dest_destination_id] => 64
)
[1] => Array
(
[gi_in_id] => 3
[gi_user_id] => 37251
[gi_inv_user_id] => 14564
[gi_timestamp] => 1345220045
[gi_group_id] => 2
)
[2] => Array
(
[dest_in_id] => 2
[dest_user_id] => 37251
[dest_inv_user_id] => 37257
[dest_timestamp] => 1387168510
[dest_destination_id] => 64
)
[3] => Array
(
[gi_in_id] => 3
[gi_user_id] => 37251
[gi_inv_user_id] => 14564
[gi_timestamp] => 1345220045
[gi_group_id] => 2
)
)
需要查看每个数组的时间戳差异，如果它<=天（86400），然后创建一个数组类型：
Array
(
[1387168510] => Array
(
[0] => Array
(
[dest_in_id] => 1
[dest_user_id] => 37251
[dest_inv_user_id] => 37247
[dest_timestamp] => 1387168510
[dest_destination_id] => 64
)
[1] => Array
(
[dest_in_id] => 2
[dest_user_id] => 37251
[dest_inv_user_id] => 37257
[dest_timestamp] => 1387168510
[dest_destination_id] => 64
)
)
[1345220045] => Array
(
[0] => Array
(
[gi_in_id] => 3
[gi_user_id] => 37251
[gi_inv_user_id] => 14564
[gi_timestamp] => 1345220045
[gi_group_id] => 2
)
[1] => Array
(
[gi_in_id] => 3
[gi_user_id] => 37251
[gi_inv_user_id] => 14564
[gi_timestamp] => 1345220045
[gi_group_id] => 2
)
)
)
重要提示！钥匙可能不同
立即向函数CCD_ 1发出呼吁。想做这样的事情：
usort($aInvitesRows, function($a, $b) {
$akey = array_keys($a);
$bkey = array_keys($b);
if (($b[preg_grep("/(.*?)_timestamp/", $bkey)[3]] - $a[preg_grep("/(.*?)_timestamp/", $akey)[3]]) <= 86400) {
return $b[preg_grep("/(.*?)_timestamp/", $bkey)[3]] = array($a, $b);
}
});
这项事业的成功并没有被加冕：(在这个阶段，使用usort只能按时间戳（*）排序，你做什么-不知道，地址帮助！
*
usort($aInvitesRows, function($a, $b) {
$akey = array_keys($a);
$bkey = array_keys($b);
return strcmp($b[preg_grep("/(.*?)_timestamp/", $bkey)[3]], $a[preg_grep("/(.*?)_timestamp/", $akey)[3]]);
});
function msort($array, $key, $sort_flags = SORT_REGULAR) {
if (is_array($array) && count($array) > 0) {
if (!empty($key)) {
$mapping = array();
foreach ($array as $k => $v) {
$sort_key = '';
if (!is_array($key)) {
$sort_key = $v[$key];
} else {
// @TODO This should be fixed, now it will be sorted as string
foreach ($key as $key_key) {
$sort_key .= $v[$key_key];
}
$sort_flags = SORT_STRING;
}
$mapping[$k] = $sort_key;
}
asort($mapping, $sort_flags);
$sorted = array();
foreach ($mapping as $k => $v) {
$sorted[] = $array[$k];
}
return $sorted;
}
}
return $array;
}
$arr = $aInvitesRows;
$result = array();
$item = array_shift($arr);
$akeys = array_keys($item);
$dt = new 'DateTime();
$dt->setTimestamp($item[preg_grep("/(.*?)_timestamp/", $akeys)[3]]);
$dt->setTime(0, 0, 0);
$result[$dt->getTimestamp()] = array($item);
foreach ($arr as $item) {
$akeys = array_keys($item);
$f = false;
foreach ($result as $day => $items) {
$diff = ($item[preg_grep("/(.*?)_timestamp/", $akeys)[3]]) - $day;
if ($diff < 86400 && $diff > 0) {
$result[$day][] = $item;
$f = true;
break 1;
}
}
if (!$f) {
$dt = new 'DateTime();
$dt->setTimestamp($item[preg_grep("/(.*?)_timestamp/", $akeys)[3]]);
$dt->setTime(0, 0, 0);
$result[$dt->getTimestamp()] = array($item);
}
}
