Reg Exp in PHP

[Otavio]

Hello.

I have a string

$str = "Thread: 1234567890. Post by Otavio (200.123.123.12 3)";

and I need to get the *name* before the IP, and after "Post by"....
The problem is that the number after "Thread" changes, the name too
and the IP...

In other words, there are lots of strings and I need to get these
values.

Thanks for all.

I think this should work:

$pat = "/^Thread: ([0-9]{1,})\. Post by ([^(]{1,})\(([0-9\.]{1,})\)$/";

if(preg_match($ pat,$str,$match es)) {
$threadnum = $matches[1];
$poster = trim($matches[2]);
$ipaddr = $matches[3];
} else {
echo("no match");
}

Another possible RegExp:

[SNIP]

$str = "Thread: 1234567890. Post by Otavio (200.123.123.12 3)";
preg_match("/Thread:\s+(\d+) \.\s+Post
by\s+([\w\s]+)\s+\(([^)]+)\)/i",$str,$matche s);
print_r($matche s);

[/SNIP]

Will give:
Thread Number in $matches[1]
Post By Name in $matches[2]
IP in $matches[3]
