Tutorials on building a PHP development environment under Windows, methods of building a PHP environment based on apache+php+mysql, very detailed PHP configuration tutorials, friends in need can refer to it.
1. Preparation - Download the required software
apache httpd-2.2.22-win32-x86-openssl-0.9.8t.msi
php php-5.3.10-win32-vc9-x86.zip
mysql mysql-5.5.20-win32.msi
2. Install the software Install apache: Double-click installation, which is no different from installing other windows software. There are no special regulations when filling in server infomation, as long as the entered information conforms to the format. After the installation is completed, enter http://localhost in the browser. If it works! is displayed, it means apache is installed successfully. Install php: Unzip php-5.3.10-win32-vc9-x86.zip to a directory. Install mysql: Double-click to install. If you need to change the installation directory, select custom in choose setup type After the installation is complete, start configuring mysql. Just keep all the default options, but it is best to change the default encoding of mysql to utf8, set the password in the modify security settings option, enter the password twice to complete, and finally click execute to complete the configuration. 3. Integrate apache+php+mysql apache: First modify the apache configuration file so that apache supports parsing php files. The apache configuration file is httpd.conf in the conf directory of the apache installation directory. 1. Let apache parse the php file and find it in the configuration file #loadmodule vhost_alias_module modules/mod_vhost_alias.so Add in the next line (the green position is based on the directory where php is located) loadmodule php5_module "d:/develop/php/php5apache2_2.dll" phpinidir "d:/develop/php" addtype application/x-httpd-php .php .html .htm 2. Found in the configuration file directoryindex index.html changed to directoryindex index.phpindex.html 3. Modify the apache site directory and find it in the configuration file (the directory where apache is installed is different, the displayed value is different) documentroot "d:/develop/apache2.2/htdocs" changed to documentroot "d:/workspace/php"
Find again changed to php: Rename php.ini-development to php.ini as the php configuration file. Modify php.ini 1. Set the specific directory of the php extension package and find ; on windows: ; extension_dir = "ext" Change to (the value is the directory of the ext folder) ; on windows: extension_dir = "d:/develop/php/ext" 2. Enable the corresponding library function and find the line where the library needs to be enabled ;extension=php_curl.dll ;extension=php_gd2.dll ;extension=php_mbstring.dll ;extension=php_mysql.dll ;extension=php_xmlrpc.dll Remove the semicolon (comment) in front and change it to extension=php_curl.dll extension=php_gd2.dll extension=php_mbstring.dll extension=php_mysql.dll extension=php_xmlrpc.dll
3. Set time zone and find ;date.timezone = Change to date.timezone = asia/shanghai The configuration is completed, check whether the configuration is successful. Restart apache, create a new file index.php in the site directory, and enter the content: Open the browser and enter http://localhost. If the following content is displayed, the installation is successful and mysql is successfully associated. |

PHP 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 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.

The 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.

PHP 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.

PHP 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 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 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.

Using 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.
