PHP中文件名的正则表达式[关闭]

Question

I need to extract some data from the defined pattern, which is as follows:

OCC_10020811_R08_2012_13_SYH

I have to extract 'R08' out of it. I need PHP regular expression for it.

Answer 1

You dont really need a regular expression for that. Try:

 $pieces = explode('_', $string);
 echo $pieces[2];
