}</span>
效果：
方法doSomething每隔2秒执行一次
方法doSomething2每隔5秒执行一次
现在执行其他方法是同步的，可以再优化成开新线程执行这些方法，就不会阻塞主线程的定时了

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements.
