$arr = array(
0=>array('key1'=>'value1' , 'key2'=>'value2'),
1=>array('key1'=>'value1' , 'key2'=>'value3'),
2=>array('key1'=>'value2' , 'key2'=>'value4'),
999=>array('key1'=>'value2' , 'key2'=>'value5')

$result = array();
span style="color:#FF0000;">foreach ($arr as $data) {
isset($result[$data['key1']]) || $result[$data['key1']] = array();
$result[$data['key1']][] = $data['key2'];
}/span>
ksort($cityAr, SORT_NATURAL);//這個(gè)是鍵值按字母先后順序排列
print_r($result);
//輸出如下
Array
(
[value1] => Array
(
[0] => value2
[1] => value3
)
[value2] => Array
(
[0] => value4
[1] => value5
)
)
以上這篇PHP讓數(shù)組中有相同值的組成新的數(shù)組實(shí)例就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
