今天鼓捣了一天的MangoDB3.x，在官网上面下载的，安装完毕之后可以连上数据库。
然后是在Php7的环境下使用，于是我去https://pecl.php.net/package/mongodb下载了最新版，后来由于不行我多次下载了其他版本依然没效果。
下载完成之后，我放到了ext文件夹，然后在php.ini里面新增了：
;添加php7对MongoDB3.x的支持
extension=php_mongodb.dll
然后重启，phpinfo()之后没有相关MongoDB模块出现。而且像
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017"); 这种命令不能使用，报： Uncaught Error: Class 'MongoDB\Driver\Manager' not found
我看https://pecl.php.net/package/mongodb最下面好像需要PEAR Package，我于是乎安装了它：
D:\php\php7>pear install PEAR
pear/PEAR is already installed and is the same as the released version 1.10.1
install failed
安装完之后，重启Apache依然不行，所以特来向前辈求助，谢谢。
回复讨论(解决方案)
phpinfo必须有模块显示
查看其他php.ini编辑一下

php.ini编辑没有问题啊，不就是指定了ext目录之后，把dll添加过去。

解决了，必须得把php的安装目录加到PATH里面，晕，就这一点搞了一天半。。。
设置环境变量不是绿色做法
你可在 httpd.conf 中用 LoadFile 指令加载 php7ts.dll
如果还有其他的支撑库不能自动加载的话，同样也可用 LoadFile 指令预先加载

学习了，找到你说的那个dll了，感觉还是设置成path吧，一步到位。。
PHP: An Introduction to the Server-Side Scripting LanguageApr 16, 2025 am 12:18 AMPHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.
PHP and the Web: Exploring its Long-Term ImpactApr 16, 2025 am 12:17 AMPHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.
Why Use PHP? Advantages and Benefits ExplainedApr 16, 2025 am 12:16 AMThe core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
Debunking the Myths: Is PHP Really a Dead Language?Apr 16, 2025 am 12:15 AMPHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.
The PHP vs. Python Debate: Which is Better?Apr 16, 2025 am 12:03 AMPHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.
PHP's Purpose: Building Dynamic WebsitesApr 15, 2025 am 12:18 AMPHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.
PHP: Handling Databases and Server-Side LogicApr 15, 2025 am 12:15 AMPHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.
How do you prevent SQL Injection in PHP? (Prepared statements, PDO)Apr 15, 2025 am 12:15 AMUsing preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
