给定这个数组:
array(1) {
[0]=>
array(2) {
["Project"]=>
array(5) {
["id"]=>
string(1) "2"
["user_id"]=>
string(2) "21"
["customer_id"]=>
string(1) "4"
["name"]=>
string(15) "WordPress Theme"
["created"]=>
string(19) "2011-09-26 21:30:38"
}
["Track"]=>
array(1) {
[0]=>
array(8) {
["id"]=>
string(1) "7"
["user_id"]=>
string(2) "21"
["project"]=>
string(1) "2"
["customer"]=>
string(1) "4"
["title"]=>
string(7) "Backend"
["notes"]=>
string(0) ""
["created"]=>
string(19) "2011-09-28 22:21:22"
["Lapse"]=>
array(2) {
[0]=>
array(5) {
["id"]=>
string(1) "4"
["track_id"]=>
string(1) "7"
["start"]=>
string(19) "2011-09-28 22:22:21"
["stop"]=>
string(19) "2011-09-28 22:22:30"
["created"]=>
string(19) "2011-09-28 22:22:21"
}
[1]=>
array(5) {
["id"]=>
string(1) "3"
["track_id"]=>
string(1) "7"
["start"]=>
string(19) "2011-09-28 22:22:07"
["stop"]=>
string(19) "2011-09-28 22:22:12"
["created"]=>
string(19) "2011-09-28 22:22:07"
}
}
}
}
}
}
我将如何组一天在失效数组与PHP?这可能更容易直接与MySQL,但我使用CakePHP的递归函数,我不知道如何使用组By !
$list = array();
function extractByDates($arr) {
foreach ($arr as $key => $v)
if (is_array($v))
function extractByDates($v);
else if ($key == 'created')
$list[$v] = $v;
}
extractByDates($yourGivenArray);
我没有测试!
