<code>php</code><code>$pinyin = array( array('name'=>'梁朝伟','age'=>23), array('name'=>'andy','age'=>24), array('name'=>'黎明','age'=>19), array('name'=>'郭富城','age'=>20) ); </code>
name字段转为拼音然后按字母排序,如果第一个字母相同比较第二个,希望结果为
<code>php</code><code>$pinyin = array( array('name'=>'andy','age'=>24), array('name'=>'郭富城','age'=>20) array('name'=>'梁朝伟','age'=>23), array('name'=>'黎明','age'=>19), ); </code>

最近也碰到了要对汉字排序的问题, Collator 效果还不错, 参考 Comparing UTF-8 String
<code>$name = [...]; (new \Collator('zh-CN'))->asort($name); var_dump( $name ); </code>
实际前后:
<code> 0 => '袁次阳' 1 => '段纪明' 2 => '朱公伟' 3 => '朱文渊' 4 => '朱符' 5 => '卢子干' 6 => '皇甫义真' 7 => '阎忠' 8 => '王子师' 9 => '士孙君荣' 10 => '荀慈明' 11 => '黄世英孙' 12 => '赵子柔' 13 => '蔡伯喈' 14 => '蔡文姬' 15 => '杨文先' 16 => '杨德祖' 17 => '吴匡' 18 => '马翁叔' 19 => '郑公业' 20 => '丁建阳' 21 => '尉韩暹' 22 => '胡才' 23 => '李乐' 24 => '杨奉' 25 => '张雅叔' 26 => '杨丑' 27 => '眭白兔' 28 => '蒋石' 29 => '吉本' 30 => '吉文然' 31 => '吉思然' 32 => '耿季行' 33 => '司直韦晃' 34 => '郎中张钧' </code>
=>
<code> 13 => '蔡伯喈' 14 => '蔡文姬' 20 => '丁建阳' 1 => '段纪明' 32 => '耿季行' 22 => '胡才' 6 => '皇甫义真' 11 => '黄世英孙' 29 => '吉本' 31 => '吉思然' 30 => '吉文然' 28 => '蒋石' 34 => '郎中张钧' 23 => '李乐' 5 => '卢子干' 18 => '马翁叔' 9 => '士孙君荣' 33 => '司直韦晃' 27 => '眭白兔' 8 => '王子师' 21 => '尉韩暹' 17 => '吴匡' 10 => '荀慈明' 7 => '阎忠' 26 => '杨丑' 16 => '杨德祖' 24 => '杨奉' 15 => '杨文先' 0 => '袁次阳' 25 => '张雅叔' 12 => '赵子柔' 19 => '郑公业' 4 => '朱符' 2 => '朱公伟' 3 => '朱文渊' </code>
<code>$sort = array(); foreach($pinyin as $key => $item) { $py = zhcnToPinyin($item['name']); $pinyin[$key]['pinyin'] = $py; $sort[] = $py; } array_multisort($sort, SORT_ASC, $pinyin); function zhcnToPinyin() { //TODO 汉字转拼音 } </code>
楼上正解,手册看一下array_multisort()
不懂楼主的做法,汉字排序时本来就是按拼音顺序排的,因为汉字编码表本身就是按照字母顺序来的。echo "梁朝伟" 拼音排序还要用拼音库的都太缺乏基础知识了。
@incNick 其实GBK编码也不是完全按照首字母排序的,你可以去查一查GBK编码表,希望大家不要被误导

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
