这样的二维数组合并并去掉重复值，该怎么做
这样的二维数组合并并去掉重复值（attr_id，attr_name，attr_value三个字段都相同的则保留一个去除一个）
- PHP code

——解决方案——————–
function array_multi_unique($ar) {
$ar = array_map(‘serialize’, $ar);
$ar = array_unique($ar);
return array_map(‘unserialize’, $ar);
}
print_r( array_multi_unique($a) );

在唠叨老大的基础上改改
- PHP code
<?php$new = Array( '0' => Array ( 'attr_id' => '16950', 'attr_name' => '台式机CPU品牌', 'attr_value' => 'AMD', '<strong>2本文来源gaodaima#com搞(代@码$网6</strong><pre>搞gaodaima代码
attr_type’ => 1, ‘belong’ => ‘goods_sku’ ), ‘1’ => Array ( ‘attr_id’ => ‘16951’, ‘attr_name’ => ‘台式机操作系统’, ‘attr_value’ => ‘Linux’, ‘attr_type’ => 2, ‘belong’ => ‘goods_sku’ ), ‘2’ => Array ( ‘attr_id’ => ‘16955’, ‘attr_name’ => ‘售后服务’, ‘attr_value’ => ‘一年’, ‘attr_type’ => 2, ‘belong’ => ‘goods_sku’ ), ‘3’ => Array ( ‘attr_id’ => ‘16950’, ‘attr_name’ => ‘台式机CPU品牌’, ‘attr_value’ => ‘AMD’, ‘attr_type’ => 1, ‘belong’ => ‘goods’ ));// 老大的基础上改改function array_multi_unique($ar, $filter=array()) { if(!empty($filter)) { $_v = array_fill_keys($filter, ‘ ‘); $_ar = array(); foreach($ar as $k => $v) { $_ar[$k] = array_intersect_key($v, $_v); } } else { $_ar = $ar; } $_ar = array_map(‘serialize’, $_ar); $_ar = array_unique($_ar); $_ar = array_map(‘unserialize’, $_ar); if(!empty($filter)) { return array_intersect_key($ar, $_ar); } else { return $_ar; }}print_r(array_multi_unique($new, array(‘attr_id’, ‘attr_name’, ‘attr_value’)));
