iphone截图
我们可以看到从下面的阵列这是显示在iPhone / iPad的图像名称是相同的，当我尝试检查上传文件夹，它只显示最后一个图像即第三个图像。
[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
[错误] => 0
[size] => 32961
）
我们在ipad和iphone的问题，因为他们使用名称的所有图像作为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（）或任何唯一的键到名称。
$ image1 = rand（）。$ _ FILES [image1] [name];
$ image2 = rand（）。$ _ FILES [image2] [name];
$ image3 = rand（）。$ _ FILES [image3] [name];
$ b copy（$ _ FILES [image1] [tmp_name]，upload /\".$ image1）;
copy（$ _ FILES [image2] [tmp_name]，upload /\".$ image2）;
copy（$ _ FILES [image3] [tmp_name]，upload /\".$ image3）;

iphone screenshot
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 i.e third image .
[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 :)
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.
$image1 = rand().$_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);
