As we can see from this below array this is displayed in iphone/ipad the image names are same for all and when i try to check for upload folder it displayed only the last image ie third image . 正如我们从下面的数组中可以看到，这在iphone / ipad中显示，图像名称对于所有人都是相同的，当我尝试检查上传文件夹时，它只显示最后一张图像，即第三张图像。

[image1] => Array
    (
        [name] => image.jpg
        [type] => image/jpeg
        [tmp_name] => /tmp/phpewhdwx
        [error] => 0
        [size] => 44009
    )

[image2] => Array
    (
        [name] => image.jpg
        [type] => image/jpeg
        [tmp_name] => /tmp/phpwYDYBM
        [error] => 0
        [size] => 27762
    )

[image3] => Array
    (
        [name] => image.jpg
        [type] => image/jpeg
        [tmp_name] => /tmp/php0vqnB2
        [error] => 0
        [size] => 32961
    )

Ok i have found the solution :) 好的，我找到了解决方案:)

we have issue in ipad's and iphone's as they use name for all images as image.jpg so if we use multiple image this gets overridden so we need to add rand() or any unique key to the name at time of copy to folder. 我们在ipad和iphone中有问题，因为他们使用所有图像的名称作为image.jpg所以如果我们使用多个图像，这将被覆盖，所以我们需要在复制到文件夹时添加rand（）或任何唯一的键。

$image1 = rand().$_FILES["image1"]["name"];
    $image2 = rand().$_FILES["image2"]["name"];
    $image3 = rand().$_FILES["image3"]["name"];

    copy($_FILES["image1"]["tmp_name"],"upload/".$image1);
    copy($_FILES["image2"]["tmp_name"],"upload/".$image2);
    copy($_FILES["image3"]["tmp_name"],"upload/".$image3);
