PHP sorted in Chinese first letter

1> Many PHP tool classes on the network can convert Chinese characters to pinyin;

2> to sort the pinyin

The other is similar to the MySQL transcoding method:

1foreach($array  as $key=$value)  2     {  3$new _array[$key] =Iconv(' UTF-8 ', ' GBK ',$value); 4} 1foreach($array  as $key=$value)  2     {  3$new _array[$key] =Iconv(' UTF-8 ', ' GBK ',$value); 4     }  5Asort($new _array); 6foreach($new _array  as $key=$value)  7     {  8$array[$key] =Iconv(' GBK ', ' UTF-8 ',$value); 9     } 5Asort($new _array); 6foreach($new _array  as $key=$value)  7     {  8$array[$key] =Iconv(' GBK ', ' UTF-8 ',$value); 9}

MySQL implementation

If the current database encoding is Utf-8, then transcode to GBK,GBK default Chinese characters are sorted by pinyin:

From USER ASC 

If the current encoding is GBK:

Asc
