simply call this function ..with param source ,destination and size what u want :) 

function cropImage($source,$dest,$whsize) {

                $size = getimagesize($source);
                $w = $size[0];
                $h = $size[1];
                $xratio=$w/$whsize;
                $yratio=$h/$whsize;

                if($xratio > $yratio)$multiplier=$xratio;
                else $multiplier=$yratio;

                $nw=$w/$multiplier;
                $nh=$h/$multiplier;
                switch($size[2]) {
                    case '1':
                    $simg = imagecreatefromgif($source);
                    break;
                    case '2':
                    $simg = imagecreatefromjpeg($source);
                    break;
                    case '3':
                    $simg = imagecreatefrompng($source);
                    break;
                }

                $dimg = imagecreatetruecolor($nw, $nh);

                $wm = $w/$nw;
                $hm = $h/$nh;

                $h_height = $nh/2;
                $w_height = $nw/2;

                if($w> $h) {

                    $adjusted_width = $w / $hm;
                    $half_width = $adjusted_width / 2;
                    $int_width = $half_width - $w_height;

                    imagecopyresampled($dimg,$simg,-$int_width,0,0,0,$adjusted_width,$nh,$w,$h);

                } elseif(($w <$h) || ($w == $h)) {

                    $adjusted_height = $h / $wm;
                    $half_height = $adjusted_height / 2;
                    $int_height = $half_height - $h_height;

                    imagecopyresampled($dimg,$simg,0,-$int_height,0,0,$nw,$adjusted_height,$w,$h);

                } else {
                    imagecopyresampled($dimg,$simg,0,0,0,0,$nw,$nh,$w,$h);
                }
             $dest=$dest.'jpeg';
                imagejpeg($dimg,$dest,100);
        }

On the client side I'd recommend JCrop.

Sure, move the file out of the uploads directory and into a temp directory somewhere, store that location in their session, then display it back to them and let them crop it before you move it to your production area and insert it into the database.
