php - 我想动态地将数字放在图像上

Question

我想动态地将数字放在图像上。

Answer 1

取两个div。为一个 div 设置背景图像并在另一个 div 上放置一些数字。使用 css 属性（如位置、z-index）将第二个 div 放在第一个 div 上

Answer 2

There are 2 ways of doing that:

1.) In the client-side: You can use the HTML5 CANVAS API. This API allows you to draw arbitrary shapes and images inside a canvas element that is rendered into the browser. So to solve your problem you could load an image inside the canvas and after that draw a number on top of it.

2.) In the server-side: You will load the image and after that draw the number inside of it using a server-side application. Eg. an application developed using PHP, ASP.NET, Python, etc. In PHP you can use the GD library to do that.
