fgets慢,有没有其它办法
方法:
$fp = fsockopen($server, $port, $errno, $errstr ,30);fputs($fp, $send_all);stream_set_timeout($fp, 30);$result = '';while(!feof($fp)) { $result.= fgets($fp,1024);}print_r($result);
这样虽然能取到数据,可太慢了,得二十多秒。
有其它方法能读到数据吗?不要用fread,用fread取不到完整数据。
回复讨论(解决方案)
curl呢?
慢是因为网络连接,除非改变硬件环境,怎么改代码都无济于事

我看了一下资料,不太懂fread,fgets它们的原理。
fread一次性读取所有数据非常快,只是取不到完整的数据,只能取一千多字节。
while fgets每次取1024的话,就能全部取到。可就非常慢了。
是不是每次fgets都是要重新去链接一次,所以循环如果有十几次每次时间叠加就会慢下来?
fgets, fread都是不直接参与连接的。数据包到达后会存放在缓冲区,他们读的是本机的缓冲区,所以不会影响速度。
fread 读取指定大小的数据块,直到文件结束。如果无法判定文件结束,则会出现等待而导致失败。
fgets 读取指定大小的数据块,会在遇到换行符是停止读取,直到文件结束
获取远程数据,一般用 file_get_contents 就可以了
如果你整个文件不大于8k的,不如把1024去掉试试看
找到原因了。
服务器上面MTU包做了限制。

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.

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.

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.

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.

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.

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
