I want to write a blog. Later, because there is no time, some code I feel that I don't feel very well, so I gave up the road; I saw 9CBS out of blog, huh, huh. This is fine, don't have it. .
Now give a PHP code that you can think of writing, this code refers to the RSS 2.0 norm of bamboo shoots. Because of its limited level, it is not very understandable to XML. I hope that the broad masses of the people will criticize and correct, thank you.
