php获取页面内容
想获取一个页面中的部分内容,代码如下,运行结果为空,不知道为啥
$con= file_get_contents("http://www.meishij.net/zuofa/gouqiboluoyinertang_5.html");$preg ='#<div class="edit">(.*)</div>#'; preg_match_all($preg, $con, $arr); //搜索内容赋值给数组print_r($arr);
就是想截取之间的内容
回复讨论(解决方案)
$preg=
内容取回来后,$con都是空的。肯定没值啊
感觉这个做法不大对,
到最后一个
但不一定是对应的标签闭合关系
的确 $con 没结果,不知道为啥不能抓取这个页面的内容呢
$con= file_get_contents("http://www.meishij.net/zuofa/gouqiboluoyinertang_5.html");
echo $con;
哪位大神指导,为啥$con是空值
$ch = curl_init();curl_setopt($ch, CURLOPT_URL, "http://www.meishij.net/zuofa/gouqiboluoyinertang_5.html");curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);$con=curl_exec($ch);curl_close($ch);echo $con;
楼上用的是报文头的方式可以返回正常的,可是为什么用file_get_contents()不可以啊!!
一样是可以的,由于他检查了是否是浏览器访问,所以要伪造一下
$url = 'http://www.meishij.net/zuofa/gouqiboluoyinertang_5.html';$opts = array( 'http'=>array( 'user_agent' => "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)", ) ); $context = stream_context_create($opts); $con = file_get_contents("http://www.meishij.net/zuofa/gouqiboluoyinertang_5.html", false, $context);

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,

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.

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 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.
