本文实例讲述了thinkPHP线上自动加载异常与修复方法。分享给大家供大家参考,具体如下:
项目遇到一个奇怪的问题,本地代码正常,服务器上却不正常。
经过测试,应该是自动加载出了问题,尝试了各种方法,
1.手动加载,发现好麻烦,没完没了。
2.自己写自动加载,写不出来,尴尬。
3.修改配置,使其支持自动加载,发现还是不行。
后来进行调试,
发现本地支持
import('@.ORG.OSS\OssClient'); import('@.ORG.OSS\Core\OssUtil');
而服务器上,不支持这种斜杠的方式,却支持.的方式
后来就把thinkphp核心代码,进行调整。
// 根据自动加载路径设置进行尝试搜索 $paths = explode(',',C('APP_AUTOLOAD_PATH')); foreach ($paths as $path){ $class = str_replace("\\",".",$class); // dump($class); if(import($path.'.'.$class)){ // dump($path.'.'.$class); // 如果加载类成功则返回 return ; } }
经过这个小小的动作,可以了,服务器可以使用OSS了。
不容易啊!

希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。

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.
