php将两个二维数组按具有相同值合并

数组一：
array(5) {
[0]=>
array(3) {
["id"]=>
string(4) "1"
["date"]=>
string(10) "2018-08-31"
["time"]=>
string(10) "1532770482"
}
[1]=>
array(3) {
["id"]=>
string(4) "2"
["date"]=>
string(10) "2018-09-2"
["time"]=>
string(10) "1534920401"
}
[2]=>
array(3) {
["id"]=>
string(4) "3"
["date"]=>
string(10) "2018-09-3"
["time"]=>
string(10) "1534920401"
}
[3]=>
array(3) {
["id"]=>
string(4) "4"
["date"]=>
string(10) "2018-09-5"
["time"]=>
string(10) "1534920401"
}
[4]=>
array(3) {
["id"]=>
string(4) "5"
["date"]=>
string(10) "2018-09-6"
["time"]=>
string(10) "1534920401"
}
}

数组二：
array(8) {
[0]=>
array(3) {
["id"]=>
int(0)
["date"]=>
string(10) "2018-08-30"
["week"]=>
string(9) "星期四"
}
[1]=>
array(3) {
["id"]=>
int(1)
["date"]=>
string(10) "2018-08-31"
["week"]=>
string(9) "星期五"
}
[2]=>
array(3) {
["id"]=>
int(2)
["date"]=>
string(10) "2018-09-01"
["week"]=>
string(9) "星期六"
}
[3]=>
array(3) {
["id"]=>
int(3)
["date"]=>
string(10) "2018-09-02"
["week"]=>
string(9) "星期日"
}
[4]=>
array(3) {
["id"]=>
int(4)
["date"]=>
string(10) "2018-09-03"
["week"]=>
string(9) "星期一"
}
[5]=>
array(3) {
["id"]=>
int(5)
["date"]=>
string(10) "2018-09-04"
["week"]=>
string(9) "星期二"
}
[6]=>
array(3) {

[7]=>
array(3) {
["id"]=>

Answer 2

$tmpArray = array();
foreach ($laArray as $row) {
$key = $row['name'] . $row['age'];
if (array_key_exists($key, $tmpArray)) {
$tmpArray[$key]['id'] = $tmpArray[$key]['id'] . '+' . $row['id'];
if (is_array($tmpArray[$key]['moeny'])) {
$tmpArray[$key]['moeny'][] = $row['moeny'];
} else {
$tmpArray[$key]['moeny'] = array($tmpArray[$key]['moeny'], $row['moeny']);
}
} else {
$tmpArray[$key] = $row;
}
}

echo "<pre>";
var_dump($tmpArray);
