xml与json之间的转换方法(附代码)
这篇文章主要介绍了php实现xml与json之间的相互转换功能,结合实例形式分析了php实现xml转json及json转xml的相关原理与实现技巧,具有一定参考借鉴价值
用php实现xml与json之间的相互转换:
相关函数请查看php手册。
一、参考xml如下
<?xml version="1.0" encoding="UTF-8"?> <humans> <zhangying> <name>张三</name> <sex>男</sex> <old>26</old> </zhangying> <tank> <name>tank</name> <sex> <hao>yes</hao> <aaaa>no</aaaa> </sex> <old>26</old> </tank> </humans>
二、xml转换成json
利用simplexml
public function xml_to_json($source) { if(is_file($source)){ //传的是文件,还是xml的string的判断 $xml_array=simplexml_load_file($source); }else{ $xml_array=simplexml_load_string($source); } $json = json_encode($xml_array); //php5,以及以上,如果是更早版本,请查看JSON.php return $json; }
三、json转换成xml
利用递归函数
public function json_to_xml($source,$charset='utf8') { if(empty($source)){ return false; } //php5,以及以上,如果是更早版本,请查看JSON.php $array = json_decode($source); $xml =''; $xml .= $this->change($array); return $xml; } public function change($source) { $string=""; foreach($source as $k=>$v){ $string .="<".$k.">"; //判断是否是数组,或者,对像 if(is_array($v) || is_object($v)){ //是数组或者对像就的递归调用 $string .= $this->change($v); }else{ //取得标签数据 $string .=$v; } $string .=""; } return $string; }
上面的方法json_to_xml,可以支持

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 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 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 mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

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.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.
