php二维数组去重
方法一：降维去重
if (!$isPidArrKey) {
//降维去重
$temp = array();
foreach ($tmp as $k => $v) {
$v = implode(,, $v);
$temp[] = $v;
}
$temp = array_unique($temp);
foreach ($temp as $k => $v) {
$temp[$k] = explode(",", $v);
}
$tmp = $temp;
}
方法二：借助第三个数组去重
$idsTmp = array();
$com = new CacheCombusiness();
foreach ($proInfo as $key => $value) {
foreach ($comInfo as $k => $v) {
if ($value[cid] == $k) {
// $value[cid] = 24;
$comBusInfo = $com->getMore(array($value[cid]));
if (!empty($comBusInfo)) {
}
if (in_array($value[pid], $idsTmp)) {
continue;
}
$idsTmp[] = $value[pid];
if ($isPidArrKey) {
$tmp[$key] = array_merge($value, $v);
} else {
$tmp[] = array_merge($value, $v);
}
}
}
}
