Question

I have a CSS (or HTML or JS) file with a comment /* Version: 1.2.1 */ near the beginning of the file.

Using PHP/regex, how do I get a string containing '1.2.1'?

I apologise for not RTFM but I can't find an answer on the Google. Any direction on learning regex would be great!

Answer 1

$str = '/* Version 1.2.1 */';
preg_match('/version\s(.*)\s\*/i',$str,$matches);

print_r($matches[1]);

its very simple to grap, \s(.*)\s capture anything in between spaces as first group. display first captured group $matches[1]

if you are curious that how it works or wanna learn yourself ? you can dive directly into it from here i found this very helpful for beginner.

Regular Expressions!
