本文实例讲述了PHP数组实现根据某个键值将相同键值合并生成新二维数组的方法。分享给大家供大家参考，具体如下：
源数据：
36,'b' => 'xa','c' => '2015-08-28 00:00:00','d' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),array(
'a' => 3,'b' => 'vd','c' => '2015-08-20 00:00:00',array(
'a' => 6,'b' => 'wwe',array(
'a' => 36,'b' => 'se','b' => 'aw','b' => 'bv',array(
'a' => 12,'b' => 'xx','c' => '2015-08-27 00:00:00','d' => '2015/08/438488a00b3219929282e3652061c2e3.png'
)
);
处理要求：将数组中a相同的二维数组合并到一个数组中，生成一个新的数组
代码：
PHP;">
$info) {
$result[$info['a']][] = $info;
}
print_r($result);
输出：
Array

[a] => 36
