Question

在php中上传图片的最佳做法是什么，尤其是大型图片，我可以阅读任何网站以获取更多相关信息，使用javascript和jquery也会很酷。这是我目前使用的功能。

    function resizeImage($image, $width, $height, $scale) {
list($imagewidth, $imageheight, $imageType) = getimagesize($image);
$imageType = image_type_to_mime_type($imageType);
$newImageWidth = ceil($width * $scale);
$newImageHeight = ceil($height * $scale);
$newImage = imagecreatetruecolor($newImageWidth, $newImageHeight);
switch ($imageType) {
    case "image/gif":
        $source = imagecreatefromgif($image);
        break;
    case "image/pjpeg":
    case "image/jpeg":
    case "image/jpg":
        $source = imagecreatefromjpeg($image);
        break;
    case "image/png":
    case "image/x-png":
        $source = imagecreatefrompng($image);
        break;
}
imagecopyresampled($newImage, $source, 0, 0, 0, 0, $newImageWidth, $newImageHeight, $width, $height);

switch ($imageType) {
    case "image/gif":
        imagegif($newImage, $image);
        break;
    case "image/pjpeg":
    case "image/jpeg":
    case "image/jpg":
        imagejpeg($newImage, $image, 90);
        break;
    case "image/png":
    case "image/x-png":
        imagepng($newImage, $image);
        break;
}

chmod($image, 0777);

}

就最佳做法而言，请始终检查MIME TYPE并尝试远离将文件和文件夹权限设置为777
