array_walk_recursive 使用匿名函数的问题
发现我的本地phpStudy集成环境PHP5.3.26可以在第二个参数传入一个匿名函数,但是部署到公司内网的测试linux主机上使用php5.3.27运行就不支持,要传一个函数名的字符串进去让它执行才可以,请问到底怎样设置才能使它支持匿名函数呢?
回复讨论(解决方案)
5.3 开始可以使用匿名函数了,应该没有问题。建议贴出代码和错误信息以供分析。
$arr = array(1,2,3,4,5);
array_walk_recursive($arr, function($value){
echo $value;
});
E_WARNING, array_walk_recursive() expects parameter 2 to be a valid callback, no array or string given
============
除非定义这个函数,然后以字符串方式传入函数名称
你的php版本多少,echo phpversion(); 看看。
好像不支持这种写法
你的php版本多少,echo phpversion(); 看看。
5.3.27
==========
好像不支持这种写法
我phpstudy的5.3.26的可以
这有什么?
5.3.26的可以,5.3.27的不可以,5.3.29的又可以
显然是版本维护中出现的失误,换个版本就是了
按照版本维护的一般规律,小版本号是偶数的,稳定性较高
现在 5.5 都正式发行了,还纠结于那些低版本中干什么?

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.

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.

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.

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.

In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

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.
