缩略图的问题,麻烦知道的帮我下,急!!!!!!!!!
如何实现上传一张图片后不生成缩略图,但可以以等比例缩小或者放大的形式来显示图片,麻烦懂的附上代码,谢谢大家!
------解决方案--------------------
jquery 一大堆这样的插件.
------解决方案--------------------
上传一张图片后本来就不生成缩略图。
显示时设置width和height都试过了吗?
如果不行。就用js/jquery来实现吧。
------解决方案--------------------
有。生成缩略图。
------解决方案--------------------
把你的js代码用php实现,
或者找百度,嗖嗖一下php 图片缩放。例子一大堆
------解决方案--------------------
为什么要让php来干呢,觉得服务器还不够累嘛?展示的部分就交给展示的部分去处理好了.啥都让php来干...又不是为了生产缩略图......
------解决方案--------------------
只需单一的设置width或height即可,何必要用js?

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
