php 二维数组
Array ( [0] => Array ( [AdminName] => sysadm [MenuNo] => ) [1] => Array ( [AdminName] => 00000 [MenuNo] => 30,27,32 ) [2] => Array ( [AdminName] => 00000 [MenuNo] => 25,26,27 ) [3] => Array ( [AdminName] => 00001 [MenuNo] => 30,27,32 ) )
数组如上：如何合并AdminName相同的，把MenuNo的值合并到一块
Array ( [0] => Array ( [AdminName] => sysadm [MenuNo] => ) [1] => Array ( [AdminName] => 00000 [MenuNo] => 30,27,32，25,26,27 ) [2] => Array ( [AdminName] => 00001 [MenuNo] => 30,27,32 ) )
------解决方案--------------------
这在计算方法中称为“聚类”
Array ( [0] => Array ( [AdminName] => sysadm [MenuNo] => ) [1] => Array ( [AdminName] => 00000 [MenuNo] => 30,27,32 ) [2] => Array ( [AdminName] => 00000 [MenuNo] => 25,26,27 ) [3] => Array ( [AdminName] => 00001 [MenuNo] => 30,27,32 ) )

$ar = array (

1 => array ( 'AdminName' => '00000', 'MenuNo' => '30,27,32' ),
2 => array ( 'AdminName' => '00000', 'MenuNo' => '25,26,27' ),
3 => Array ( 'AdminName' => '00001', 'MenuNo' => '30,27,32' ),
);
$res = array();
foreach($ar as $row) {
if(! isset($res[$row['AdminName']])) $res[$row['AdminName']] = $row;
else $res[$row['AdminName']]['MenuNo'] .= ',' . $row['MenuNo'];
}
print_r(array_values($res));
Array
(
[0] => Array
(
[AdminName] => sysadm
[MenuNo] =>
)
[1] => Array
(
[AdminName] => 00000
[MenuNo] => 30,27,32,25,26,27
)
[2] => Array
(
[AdminName] => 00001
[MenuNo] => 30,27,32
)
)
