How to use php to intercept specific paragraphs

For example, you can enter a string of characters in a text box.
Content entered for the first time: $ w1 = "http://you.video.sina.com.cn/ B /25323843-1272884840.html ";
Second input: $ w2 = "http://v.youku.com/v_show/id_XMzIzNjA2NjE2.html ";


First result: $ val = "25323843 ";
The second result: $ val = "XMzIzNjA2NjE2 ";

Assuming that the above two values are entered by the user separately, how does the program automatically extract the values I need? Can you give an example?


Please help
