[RESOLVED] preg_match

[vbbit]

Can anyone explain this little for e about the regular expr.


"/^(http:\/\/info@)?([^\/]+)/i"


I understand the first part, but after the "?" I dont' get it.

match any character that isn't a "/" as many times as possible (greedy)

I still don't get it, what do you mean. Could you give me an example of a phrase or a URL?

^ is the inversion operator;
\/ is the escaped form of / since the expression uses / as the delimiter;
[] denotes a character class;
[^\/] matches any character that is not /
+ means match at least once;
[^\/]+ means match at least one character that is not /
The i flag means match case-insensitively.

You can make it a bit less ugly by changing the delimiter to something else:
#^(http://info@)?([^/]+)#i
