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8a11bc632ea32a57b3e3693c7987c420aaaadf406f776eecbaf16b62325323196f14,不支持c19213bbd017a780c87212c70ff17895aaaaadf406f776eecbaf16b62325323196f14看代码就能看明白.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.
