现有多张短图，拼接成一张长图，如何简单实现？
$v) {
$source[$k]['source'] = Imagecreatefromjpeg($v);
$source[$k]['size'] = getimagesize($v);
}
//imagecopy ($target_img,$source[0]['source'],2,2,0,0,$source[0]['size'][0],$source[0]['size'][1]);
//imagecopy ($target_img,$source[1]['source'],250,2,0,0,$source[1]['size'][0],$source[1]['size'][1]);
$num1 = 0;
$num = 1;
$tmp = 2;
$tmpy = 2; //图片之间的间距
for ($i = 0; $i < 4; $i++) {
imagecopy($target_img, $source[$i]['source'], $tmp, $tmpy, 0, 0, $source[$i]['size'][0], $source[$i]['size'][1]);
$tmp = $tmp + $source[$i]['size'][0];
$tmp = $tmp + 5;
if ($i == $num) {
$tmpy = $tmpy + $source[$i]['size'][1];
$tmpy = $tmpy + 5;
$tmp = 2;
$num = $num + 3;
}
}
Imagejpeg($target_img, '//m.sbmmt.com/m/article/pin.jpg');
?>
imagecopyresample.
