Here is something that may help you:
function GetBetween($content,$start,$end){
$r = explode($start, $content);
if (isset($r[1])){
$r = explode($end, $r[1]);
return $r[0];
}
return '';
}
$string="Coolman United States Member Since January 2013 Loans 114.01 Active 66.00 Repaid Credentials 2 followers eBay windchester 42 Friends 2";
echo GetBetween($string,"Member Since "," Loans");
$wh = strpos($string," ");
$username = substr($string,0,$wh);
$country = substr($string,$wh,strpos($string," Member Since")-$wh);
I assume here that the username is always one word.
