[learninghard]

hi there i have this code and i'm having trouble with the $URL ,because that code import a page to a box, since they changed the layout, this no longer possible.

PHP Code:

function tjrj($process,$tipo="")
        {
            //check a origem
            if ($tipo == "95")
        $URL = "http://www.xyz.com/scripts/B=&PRO=".$process;
            else
            $sFormatted = vsprintf('%s.%s.%s-%s', sscanf($process, "%4s%3s%6s%s"));
            $URL = "http://www.xyz.com/scripts/B=&PRO=&numProcess=".$sFormatted;
            
            $pagina = $this->openURl($URL);
            $lines = explode("\r",$page);
            for ($i=28;$i <= count($lines) - 18;$i++)
            {
                        $buffer1 =  str_replace("width='770'", "width='100%'", trim($lines[$i])."\n");
                $buffer .=  str_replace("width='700'", "width='100%'", trim($buffer1)."\n");
            }
            return $buffer;
