有：阵列（[attr_Size] =＆GT; 3 [attr_Colour] =大于7）

要获取：阵列（[尺寸] =＆GT; 3 [颜色] =大于7）

您帮助将非常AP preciated ...

Your help will be much appreciated...

推荐答案

其中一个方式来获得：阵列（[尺寸] =＆GT; 3 [颜色] =＆GT; 7）从你的有：阵列（[attr_Size] =＆GT; 3 [attr_Colour] =大于7）

One of the ways To Get:Array ( [Size] => 3 [Colour] => 7 ) From your Having: Array ( [attr_Size] => 3 [attr_Colour] => 7 )

$new_arr = array();
foreach($Your_arr as $key => $value) {

list($dummy, $newkey) = explode('_', $key);
$new_arr[$newkey] = $value;

}

如果您认为会在键选择多个下划线只需更换里面的foreach第一行列表（$假人，$则newkey）=爆炸（'attr_'，$键）;

If you think there'll be multiple underscores in keys just replace first line inside foreach with list($dummy, $newkey) = explode('attr_', $key);
