PHP Regular Expression

[keval007]

Hi,

I have text file which has lots of text as well as HTML data. There are some line as shown below.

06/30/12 00:40:30.73 Sending Email - Group: 4FD7917824F1B-EMAIL, 0, Message: 

There are lots of lines like above in text file. I want to extract following data from the entire text file.

Group: 4FD7917824F1B-EMAIL

I know this can be done by regular expression but I don't know how exactly done it. Some one can please provide some regular expression for above or some explanation.

I'm crap at regex, but you could try something like this:

$str = "06/30/12 00:40:30.73 Sending Email - Group: 4FD7917824F1B-EMAIL, 0, Message:";
preg_match("/Sending Email - ([^,]*),/",$str,$matches);
echo $matches[0];

Or even:

$cut = explode(' - ',$str);
$detail = explode(',',$cut[1]);
echo $detail[0];
