PHP图片压缩解决方法

//代码如下，我自己并没有验证，先收藏起来

header("Content-type: image/jpeg");

$file = "10k.jpg";
$percent = 1.5; //图片压缩比
list($width, $height) = getimagesize($file); //获取原图尺寸
//缩放尺寸
$newwidth = $width * $percent;
$newheight = $height * $percent;
$src_im = imagecreatefromjpeg($file);
$dst_im = imagecreatetruecolor($newwidth, $newheight);
imagecopyresized($dst_im, $src_im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
imagejpeg($dst_im); //输出压缩后的图片
imagedestroy($dst_im);
imagedestroy($src_im);
