安装:
为了更好的调试PHP程序,安装一下xdebug.官方网址: http://www.xdebug.org首先下载xdebug-2.4.0rc3.tgz,在官方首页下载源代码,下载回来的文件名是:xdebug-2.4.0rc3.tgzxdebug的版本需与您的php版本相对应,由于偶的php是5.6.11,所以偶下载xdebug-2.4.0rc3.tgz#cd/your/download/path#tar zxvfxdebug-2.4.0rc3.tgzcd xdebug-2.4.0rc3运行phpize#phpize这里不需要--prefix,编译好之后直接把modules里的xdebug.so文件复制走即可。#./configure--enable-xdebug#make我把xdebug.so复制到了我的php安装目录,我装php的时候指定了安装目录,所以偶是复制到/home/developer/opt/php/xdebug里。随便你复制到哪都行,只要你清楚知道。。。需要改下面一条命令的路径为你自己的。#cp modules/xdebug.so/home/developer/opt/php/xdebug把下面这行添加到你的php.ini文件的最后。如果您定义过php.ini的存放位置,一定要找到位置哦,建议弄个phpinfo(),查看到php.ini文件的具体位置。我的位置是在:/usr/local/etc/php.ini#vim/usr/local/etc/php.ini添加下面一行:zend_extension="/home/developer/opt/php/xdebug/xdebug.so"注意,如果您安装过zend optimizer 那么,注意您的php.ini文件中是否已存在zend_extension=,如果已经存在,请注释掉,在zend_extension=前加上; ,示例:;zend_extension="/usr/local/lib/php/20060613/ZendExtensionManager.so"这样,才可以正常安装运行好xdebug.重启你的web服务器。
配置xdebug:
[xdebug]zend_extension = "/home/developer/opt/php/xdebug/xdebug.so";允许远程IDE调试xdebug.remote_enable = On;远程主机xdebug.remote_host = 192.168.231.57xdebug.remote_port = 9000 ;默认端口 9000xdebug.idekey = "PHPSTORM"xdebug.profiler_enable = On;临时跟踪信息输出xdebug.trace_output_dir = "/tmp/xdebug_logs/trace"xdebug.profiler_output_dir = "/tmp/xdebug_logs/profiler";其余参数;开启自动跟踪。自动打开"监测函数调用过程"的功模。该功能可以在你指定的目录中将函数调用的监测信息以文件的形式输出xdebug.auto_trace = On;开启异常跟踪xdebug.show_exception_trace = On;开启远程调试自动启动xdebug.remote_autostart = On;收集变量xdebug.collect_vars = On;收集返回值xdebug.collect_return = On;收集参数xdebug.collect_params = On;显示局部变量xdebug.show_local_vars = On;显示默认的错误信息xdebug.default_enable = On;用于zend studio远程调试的应用层通信协议xdebug.remote_handler = dbgp;如果设得太小,函数中有递归调用自身次数太多时会报超过最大嵌套数错xdebug.max_nesting_level = 10000

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
