php只是做网站吗?如果学php怎样规划职业道路比较好,不可能一直做网站吧。而且听说做网站一般都有后台代码只是做前台页面的设计。有没有专业的大神解释一下。谢了
回复讨论(解决方案)
前台页面设计 :html/css、js/jquery
网站功能:php+mysql 比如登陆注册、商城购物车等等
服务器:Apache、nginx

使用 PHP,并不局限于输出 HTML。PHP 还能被用来动态输出图像、PDF 文件甚至 Flash 动画(使用 libswf 和 Ming)。还能够非常简便的输出文本,例如 XHTML 以及任何其它形式的 XML 文件。PHP 能够自动生成这些文件,在服务端开辟出一块动态内容的缓存,可以直接把它们打印出来,或者将它们存储到文件系统中。
你也来写脚本,作为一种工具,虽然用得少
无论 php 被用来做什么,但 php 适用于 web 开发并可以嵌入到 HTML 中去
php就是用来做web的,这是它的优越性。
1:无论从开发角度考虑还是从经济角度考虑,PHP都比较实用.PHP属于自由软件,PHP易于入门.
2:PHP在WEB项目开发过程中具有极其强大的功能,完全跨平台的WEB开发语言.
3:PHP的应用领域很广,主要体现在网站开发或者WEB应用开发!

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
