因为我是PHP的新手，所以我正在努力解决这个问题。我正忙着帮忙整理/整理我的输出数组。
我有一个这样的数组（从SQL直接输出，多个连接）。
array(8) {
[0] = > array(2) {
["season"] = > string(1)"1"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(1)"6"
["pdatas"] = > array(1) {
[0] = > array(2) {
["name"] = > string(7)"Ligue 1"
["res"] = > string(1)"1"
}
}
}
}
}
[1] = > array(2) {
["season"] = > string(1)"1"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(1)"6"
["pdatas"] = > array(1) {
[0] = > array(2) {
["name"] = > string(15)"Coupe de France"
["res"] = > string(1)"1"
}
}
}
}
}
[2] = > array(2) {
["season"] = > string(1)"2"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(1)"6"
["pdatas"] = > array(1) {
[0] = > array(2) {
["name"] = > string(7)"Ligue 1"
["res"] = > string(1)"1"
}
}
}
}
}
[3] = > array(2) {
["season"] = > string(1)"4"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(2)"16"
["pdatas"] = > array(0) {}
}
}
}
[4] = > array(2) {
["season"] = > string(2)"11"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(2)"16"
["pdatas"] = > array(0) {}
}
}
}
[5] = > array(2) {
["season"] = > string(2)"11"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(2)"17"
["pdatas"] = > array(1) {
[0] = > array(2) {
["name"] = > string(9)"Liga BBVA"
["res"] = > string(1)"1"
}
}
}
}
}
[6] = > array(2) {
["season"] = > string(2)"11"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(2)"17"
["pdatas"] = > array(1) {
[0] = > array(2) {
["name"] = > string(12)"Copa del Rey"
["res"] = > string(1)"2"
}
}
}
}
}
[7] = > array(2) {
["season"] = > string(2)"11"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(2)"17"
["pdatas"] = > array(1) {
[0] = > array(2) {
["name"] = > string(21)"Supercoupe d\'Espagne"
["res"] = > string(1)"1"
}
}
}
}
}
}
我希望它看起来像这样：
array(5) {
[0] = > array(2) {
["season"] = > string(1)"1"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(1)"6"
["pdatas"] = > array(2) {
[0] = > array(2) {
["name"] = > string(7)"Ligue 1"
["res"] = > string(1)"1"
}
[1] = > array(2) {
["name"] = > string(15)"Coupe de France"
["res"] = > string(1)"1"
}
}
}
}
}
[1] = > array(2) {
["season"] = > string(1)"2"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(1)"6"
["pdatas"] = > array(1) {
[0] = > array(2) {
["name"] = > string(7)"Ligue 1"
["res"] = > string(1)"1"
}
}
}
}
}
[2] = > array(2) {
["season"] = > string(1)"4"
["cdatas"] = > array(1) {
[0] = > array(2) {
["id"] = > string(2)"16"
["pdatas"] = > array(0) {}
}
}
}
[3] = > array(2) {
["season"] = > string(2)"11"
["cdatas"] = > array(2) {
[0] = > array(2) {
["id"] = > string(2)"16"
["pdatas"] = > array(0) {}
}
[1] = > array(2) {
["id"] = > string(2)"17"
["pdatas"] = > array(2) {
[0] = > array(2) {
["name"] = > string(9)"Liga BBVA"
["res"] = > string(1)"1"
}
[1] = > array(2) {
["name"] = > string(12)"Copa del Rey"
["res"] = > string(1)"2"
}
[2] = > array(2) {
["name"] = > string(21)"Supercoupe d\'Espagne"
["res"] = > string(1)"1"
}
}
}
}
}
正如您所看到的：我希望在同一季节迭代第一个数组并分组cdatas。 之后，我希望迭代每个cdatas并按ID分组pdatas。
任何帮助都会受到赞赏，我会因为这些多级别和关键而迷失方向。
谢谢你们！
目前，这就是我正在做的事情，但是使用这段代码我有一些季节没有与其他季节分组，原因我不解释。
function sortCollectiveSeasonList($arrayToSort) {
$array = $arrayToSort;
for ($i = 0; $i <= count($array); $i++) {
for ($j = 0; $j <= count($array); $j++) {
if ($array[$i]['season'] == $array[$j]['season'] && $i < $j) {
//echo 'SAME SEASON FOUND season '.$array[$i][season].' and '.$array[$j][season].'';
if (isset($array[$i]['cdatas'])) {
$array[$i]['cdatas'] = array_merge($array[$i]['cdatas'], $array[$j]['cdatas']);
}
else {
$array[$i]['cdatas'] = $array[$j]['cdatas'];
}
unset($array[$j]);
}
}
//if (isset($array[$i]['cdatas']))
//$array[$i]['cdatas'] = sortList($array[$i]['cdatas']);
//else
//unset($array[$i]);
//array_push($output, $array[$i]);
}
//Reindex array
$array = array_values($array);
//Remove empty cdatas
for ($i = 0; $i < count($array); $i++) {
if (isset($array[$i]['cdatas']))
$array[$i]['cdatas'] = sortList($array[$i]['cdatas']);
else
unset($array[$i]);
}
//return $array;
return array_values($array);
}
function sortList($arrayToSort) {
$array = $arrayToSort;
for ($i = 0; $i <= count($array); $i++) {
for ($j = 0; $j <= count($array); $j++) {
if ($array[$i]['id'] == $array[$j]['id'] && $i != $j) {
if (isset($array[$i]['pdatas'])) {
$array[$i]['pdatas'] = array_merge($array[$i]['pdatas'], $array[$j]['pdatas']);
}
else {
$array[$i]['pdatas'] = $array[$j]['pdatas'];
}
unset($array[$j]);
}
}
}
//Reindex array
$array = array_values($array);
//Remove empty cdatas
for ($i = 0; $i < count($array); $i++) {
if (!isset($array[$i]['pdatas']))
unset($array[$i]);
}
//return $array;
return array_values($array);
}
