PHP的xml字符串解析(在线求解)
小弟接触php时间不长,今天遇到个问题就是解析xml字符串,内容是
<?xml version='1.0' encoding='utf-8'?><order_info><user_name>13817969688</user_name><mobile>13817969688</mobile><tel>021-54485454</tel><customer_name>刘先生</customer_name><city_name>上海</city_name><district_name>长宁</district_name><address>新中路999号4栋8楼</address><customer_word>送货前电话联系,谢谢。</customer_word><goods_infos><good><goods_id>51541</goods_id><goods_amount>1</goods_amount></good><good><goods_id>51542</goods_id><goods_amount>3</goods_amount></good></goods_infos></order_info>
用
$xml=simplexml_load_string($xmlStr);foreach($xml->order_info as $item) { oreach($item as $k=>$v) echo "$k $v\n";}
代码是网上找的,但用到我的这个上面行不通,我试了一下,一方面是因为字符串有汉字,另一方面是xml结构跟网上提供的示例不一样,请问亲们这个要怎么解析呢
回复讨论(解决方案)
header('Content-Type: text/xml');
加上这行代码试试
1、simplexml 会忽略根节点
对于你的示例数据,根节点 order_info 被忽略,所以 $xml->order_info 不存在,所以你不会有输出
打印一级子节点的值应这样写
foreach($xml->children() as $k=>$v) { if(empty($v)) //这里检查是否有子节点,如有就不打印。这样就跳过了 goods_infos echo "$k $v\n";}
2、如果是打印 goods_infos 下的 good 子节点,则写作
foreach($xml->goods_infos->good as $item) { foreach($item as $k=>$v) echo "$k $v\n";}
3、如果你的程序文件不是 utf-8 的,还应该有
$xmlStr = str_replace("encoding='utf-8'", "encoding='gbk'", $xmlStr);
即将字符集改为真实的字符集
当然打印的结果仍然是 utf-8 的
如果需要遍历所有节点,那么就需要递归
function show_child($xml) { foreach($xml->children() as $tag=>$item) { if($item) show_child($item); else echo "$tag: $item\n"; }}show_child($xml);

非常感谢你的详细解答,但现在遇到个问题是,我的xml文件在simplexml_load_string处理之前是正常的,但处理之后输出发现乱码了,而且转码好像转不过来,我的程序文件是gbk的,所以我加过$xmlStr = str_replace("encoding='utf-8'", "encoding='gbk'", $xmlStr);了
不是说了吗?
当然打印的结果仍然是 utf-8 的
因为 utf-8 是 xml 的工作语言
你需要逐个的对待打印的数据进行转码
比如 echo iconv('utf-6', 'gbk', $v);

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
