How to sort php arrays in pinyin order-php Tutorial

The {code...} name field is converted to pinyin and then sorted by letters. if the first letter is the same and the second one is compared, the result is {code ...}.

php$ Pinyin = array ('name' => 'Liang Chaowei ', 'age' => 23), array ('name' => 'Andy ', 'age' => 24), array ('name' => 'Daybreak ', 'age' => 19), array ('name' => 'kwok City ', 'age' => 20 ));

The name field is converted to pinyin and then sorted by letters. if the first letter is the same as the second one, you want the result to be

php$ Pinyin = array ('name' => 'Andy ', 'age' => 24), array ('name' => 'kwok City ', 'age' => 20) array ('name' => 'Liang Chaowei ', 'age' => 23), array ('name' => 'day ', 'age' => 19 ),);

Recently also encountered the problem of sorting Chinese characters, Collator effect is not bad, refer to Comparing UTF-8 String

$name = [...];(new \Collator('zh-CN'))->asort($name);var_dump( $name );

Before and after:

0 => 'Yuan Ziyang' 1 => 'duan jiming' 2 => 'Zhu gongwei' 3 => 'Zhu Wenyuan '4 => 'Zhu Fe' 5 => 'Lu zi gan '6 => 'Huang Fu yizhen' 7 => 'Zhong Zhong' 8 => 'Prince Shi '9 => 'Shi Sun junirong '10 => 'Yi cieming' 11 => 'Huang Shiying Sun '12 => 'Zhao Zirou '13 => 'Cai Bo qing' 14 => 'Cai Wenji' 15 => 'Yang wenxian' 16 => 'Yang de zu'17 => 'Wu Kuang '18 => 'mahoushu '19 => 'Zheng Gong Ye' 20 => 'Ding Jianyang' 21 => 'Wei Han ye'22 => 'hu Cai '23 => 'lile' 24 => 'Yang Feng' 25 => 'Zhang Yashu '26 => 'Yang ug' 27 => 'White Rabbit' 28 => 'Jiang shi' 29 => 'giben' 30 => 'givenran '31 => 'gisto' 32 => 'seasonal line' 33 => 'Division wei Huang zhi'34 => 'Lang Zhong Zhangjun'

=>

13 => 'Cai baizao' 14 => 'Cai Wenji '20 => 'Ding jianyang' 1 => 'duan jiming' 32 => 'seasonal line' 22 => 'hu cai '6 => 'Huang Fu yizhen' 11 => 'Huang Shiying Sun '29 => 'giben' 31 => 'gistro' 30 => 'givenran '28 => 'Jiang shi' 34 => 'Lang Zhong Zhangjun '23 => 'lile' 5 => 'Lu Zigan' 18 => 'mahoushu '9 => 'Shi Sun Junrong '33 => 'Wei zhihuang '27 => 'White Rabbit '8 => 'Prince Shi '21 => 'Wei Han qing' 17 => 'Wu Kuang' 10 => 'Yi cieming '7 => 'Yi Zhong' 26 => 'Yang ug' 16 => 'Yang DEZ' 24 => 'Yang Feng' 15 => 'Yang Wenxian '0 => 'Yuan Ziyang' 25 => 'Zhang Yaxiao '12 => 'Zhao Zirou' 19 => 'Zheng Gong Ye' 4 => 'Zhu Fe' 2 => 'Zhu gongwei' 3 => 'Zhu Wenyuan'

$ Sort = array (); foreach ($ pinyin as $ key = >$ item) {$ py = zhcnToPinyin ($ item ['name']); $ pinyin [$ key] ['Pinin'] = $ py; $ sort [] = $ py;} array_multisort ($ sort, SORT_ASC, $ pinyin); function zhcnToPinyin () {// Convert TODO Chinese characters to pinyin}

Upstairs, let's take a look at array_multisort ()

The Chinese character encoding table is in alphabetical order. Echo "Liang Chaowei" <"Dawn" returns true.
The sorting of pinyin is too lacking in basic knowledge.

@ IncNick in fact, the GBK encoding is not fully sorted by the first letter. you can check the GBK encoding table. I hope you will not be misled.
