Hi there, I have a script that uses a RegEx to get data from a TextArea.

Here's a bit of the code I currently have:

$str = nl2br(rtrim($_POST[text]));
$num = 0;
$i = 0;
while ($i < 200)
{
preg_match_all("/Address:.[^\\n]*/i", $str, $matches);
foreach ($matches as $val) {
$txtol = $val[$num];
echo $txtol;
}
$i++;
$num++;
}

I was just wondering if anyone knew how I could echo what was two lines above the "Address:" line?

Eg. If someone put this in the textarea:

BlahBlah
Hello
Blah
Address: moretext
Stuff

How could I echo "Hello" without knowing what was put in the textbox?

$str_arr = explode("\n", $str);
foreach ($str_arr as $key => $val) {
    if (strpos($val, 'Address') !== false) {
        if ($key >= 2) {
            $two_lines_above = $str_arr[$key - 2];
        }
        break;
    }
}

Thanks, but I can't exactly get it to work right, if I have more than one "Address:", it displays the same one twice.
How do I make it go two lines above each match?

Thanks.
