在下面的表单和处理文件中，我尝试上传3种尺寸的多张图片上传，并且上传3种尺寸完全正常。
但是它会在所选最后一张图像的所有尺寸上上传相同的图像。
更新
我观察到必须使用$src播放的内容我在下面尝试过，当我这样做时，图像保存为黑色。 $src不接受[$Kv]
foreach($_FILES['file']['tmp_name'] as $src[$Kv]) {
if($extension[$Kv]=="jpg" || $extension[$Kv]=="jpeg" ){
$uploadedfile[$Kv] = $_FILES['file']['tmp_name'][$Kv];
$src[$Kv] = imagecreatefromjpeg($uploadedfile[$Kv]);
}
list($width,$height)=getimagesize($uploadedfile[$Kv]);
////// 1st Size of Image
$newwidth=350;
$newheight=350;
$tmp[$Kv]=imagecreatetruecolor($newwidth,$newheight);
imagecopyresampled($tmp[$Kv],$src[$Kv],0,0,0,0,$newwidth,$newheight,$width,$height);
}
Suppose I selected 3 images to upload.
Image A
Image B
Image C
它正在转换和上传所有图像的所有尺寸（3x3），但所有选定图像尺寸的图像显示是图像C 的图像。
你可以帮我解决这个问题，我错了吗？
感谢。

答案 0 :(得分：0)
最后，我得到了我想要的工作。
