Finding and retrieving text

Shroder01

I'm trying to pull ip address's and other information from emails that I will put into text files and I'm trying to figure out how I can find certain information and then just set it as a variable.

I've looked into strstr(); but it doesn't do what I want. Plus I don't think I can find a ... entry (ip address).

Any ideas? Thanks!

you need RegExp... I am new to that myself but I believe you could look for an IP address like thi:

/([0-9]+.[0-9]+.[0-9]+.[0-9]+)/

that would be your search string

then you can call the resutl with \1

I forgot about Regexp. I haven't had much experience with them and doing this actually made me realize what they are for now. I'm having a problem pulling the words it find out of the array though. This is the code I have. So what am I doing wrong?

$frog = "yanky doodle";

if (eregi("yanky", $frog, $regs)) {

echo "$regs[1]";
}
else
{
echo "this did not work";
}
