用于php评论的java正则表达式

Question

hello i am writing a java program to remove all comment from a string that conatins php source code can any one give me regular expression for php comment ?? please

Answer 1

Have a look at this link: http://ostermiller.org/findcomment.html

He arrives at this solution (for /* ... */ comments):

sourcecode.replaceAll("/\\*(?:.|[\
\])*?\\*/","");

For // ... and # ... comments you should be able to do something like

sourcecode.replaceAll("(//|#).*?[\
\]");

Beware of the following type of situations though:

• someString = "An example comment: /* example */";

• someString = "An example comment: // example";

• someString = "An example comment: # example";
