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
源数据
$infos = array(
array(
'a' => 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',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 6,
'b' => 'wwe',
'c' => '2015-08-28 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 36,
'b' => 'se',
'c' => '2015-08-28 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 6,
'b' => 'aw',
'c' => '2015-08-28 00:00:00',
'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'

'd' => '2015/08/438488a00b3219929282e3652061c2e3.png'
),
array(
'a' => 12,
