Two-dimensional code online generation of graphics PHP source code

Two-dimensional code is now becoming more and more popular, here is a description of both ends of PHP two-dimensional code generation code, a section of the use of Google-open two-dimensional Code API, another section using PHP QR code two-dimensional source class library, are very simple.

1, using Google Chart API to generate two-dimensional code picture

Google Chart API is a very powerful API, generating two-dimensional code is only one of the small functions. Here only the two-dimensional code section, if you want to know more features, you can login to the official website address: http://code.google.com/intl/zh-CN/apis/chart/

The code is as follows:

　　

$urlToEncode = "Http://www.weste.net";
