PHP XDebug扩充
PHP XDebug扩展
XDebug 是一个 php 代码的调试工具, 对程序员调试程序有很大的帮助。很多PHP程序员调试习惯使用echo、print_r()、var_dump()、printf()等，但是代码写好了，能运行了，不代表它的质量就过关了。有时候代码没有明显的编写错误，没有显示任何错误信息（如error、warning、notice等），但是这不表明代码就是正确无误的。有时候可能某段代码执行时间过长，占用内存过多以致于影响整个系统的效率，我们没有办法直接看出来是哪部份代码出了问题。这时候我们希望把代码的每个阶段的运行情况都监控起来，XDebug就可以为你做这些事情。更重要的是做为一个开发者，也应该要养成使用调试工具的习惯，这样可以提高开发效率和质量。
XDebug的安装，我自己试过了，挺简单，不懂得可以找我，呵呵。
以下提供几个参考链接大家也可以自己学着安装。

What does http status code 520 mean?
Oct 13, 2023 pm 03:11 PM
HTTP status code 520 means that the server encountered an unknown error while processing the request and cannot provide more specific information. Used to indicate that an unknown error occurred when the server was processing the request, which may be caused by server configuration problems, network problems, or other unknown reasons. This is usually caused by server configuration issues, network issues, server overload, or coding errors. If you encounter a status code 520 error, it is best to contact the website administrator or technical support team for more information and assistance.

Sep 26, 2023 am 11:19 AM
How to use NginxProxyManager to implement automatic jump from HTTP to HTTPS. With the development of the Internet, more and more websites are beginning to use the HTTPS protocol to encrypt data transmission to improve data security and user privacy protection. Since the HTTPS protocol requires the support of an SSL certificate, certain technical support is required when deploying the HTTPS protocol. Nginx is a powerful and commonly used HTTP server and reverse proxy server, and NginxProxy
Understand common application scenarios of web page redirection and understand the HTTP 301 status code
Feb 18, 2024 pm 08:41 PM
Understand the meaning of HTTP 301 status code: common application scenarios of web page redirection. With the rapid development of the Internet, people's requirements for web page interaction are becoming higher and higher. In the field of web design, web page redirection is a common and important technology, implemented through the HTTP 301 status code. This article will explore the meaning of HTTP 301 status code and common application scenarios in web page redirection. HTTP301 status code refers to permanent redirect (PermanentRedirect). When the server receives the client's
What is http status code 403?
Oct 07, 2023 pm 02:04 PM
HTTP status code 403 means that the server rejected the client's request. The solution to http status code 403 is: 1. Check the authentication credentials. If the server requires authentication, ensure that the correct credentials are provided; 2. Check the IP address restrictions. If the server has restricted the IP address, ensure that the client's IP address is restricted. Whitelisted or not blacklisted; 3. Check the file permission settings. If the 403 status code is related to the permission settings of the file or directory, ensure that the client has sufficient permissions to access these files or directories, etc.
Quick Application: Practical Development Case Analysis of PHP Asynchronous HTTP Download of Multiple Files
Sep 12, 2023 pm 01:15 PM
Quick Application: Practical Development Case Analysis of PHP Asynchronous HTTP Download of Multiple Files With the development of the Internet, the file download function has become one of the basic needs of many websites and applications. For scenarios where multiple files need to be downloaded at the same time, the traditional synchronous download method is often inefficient and time-consuming. For this reason, using PHP to download multiple files asynchronously over HTTP has become an increasingly common solution. This article will analyze in detail how to use PHP asynchronous HTTP through an actual development case.
Will enabling XDebug on a production server make PHP slower?
Sep 22, 2023 pm 10:41 PM
Yes, debuggers like XDebug can slow down PHP server performance. This is why the debugger is not placed in a server environment. They are deployed in different environments to avoid unnecessary overhead. Debug messages cannot be displayed in applications that are already in production. When debugging behavior is added to the server, the debugging engine is attached to the PHP process. It starts receiving messages to stop at the breakpoint, but this is not required behavior as it would give a performance hit to other processes, thus stopping the PHP parser. On the other hand, when debuggers are installed, they tend to open ports in the server because they are not intended for use in a production environment. Opening a port in your server is just as bad as opening a door for hackers to snoop through.
