After downloading, unzip the compressed package, find the ZendLoader.dll file in the ZendGuardLoader-php-5.3-WindowsZendServerlibloaderphp-5.3.x directory, and put it in the ext directory of your php directory:
Then edit the php.ini file and add a piece of code (eg):
[Zend.loader] zend_loader.enable=1 zend_loader.disable_licensing=1 zend_loader.obfuscation_level_support=3 zend_loader.license_path= zend_extension=”D:\php\ext\ZendLoader.dll”
Save the php.ini configuration file and restart apache or IIS
Create a new phpinfo() file in the www directory you specified. Enter
If the probe displays Zend Guard Loader, it means that Zend Guard has been configured successfully;
Attached: php5.3 does not support ZendOptimizer solution (Zend Guard Loader)
Under PHP 5.3, Zend Optimizer has been replaced by the new Zend Guard Loader
1. Download the Zend Guard Loader compressed package. (Official download address: http://www.zend.com/en/products/guard/downloads)
2. Unzip and extract ZendGuardLoader.so (Linux) or ZendLoader.dll (Windows), corresponding to your PHP version.
3. Add the following line to your php.ini file to load the Zend Guard Loader:
Linux and Mac OS X: zend_extension = full path/ZendGuardLoader.so
Windows (not thread-safe): zend_extension = full path/ZendLoader.dll
4. Add an extra line in php.ini to enable Zend Guard Loader:
zend_loader.enable = 1
5. Optional: You can add the following line to the Zend Guard Loader configuration location in the php.ini file:
; Disable license check (for performance reasons)
zend_loader.disable_licensing = 0
;Enable Zend Guard Loader to support obfuscation levels. Levels are detailed in the official Zend Guard documentation. 0 – Do not enable obfuscation
zend_loader.obfuscation_level_support = 3
;Look for Zend product authorized product licenses from this path. For more information on how to create a license file, see the Zend Guard User Guide.

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.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

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.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
