Question

我正在尝试使用上传图片，它在浏览器中运行完美，但它在iphone和ipad中不起作用。下面是iphone的代码和截图

test.php
---------
<?php 
    if(isset($_POST['submit']))
    {
        //echo "<pre>";
        //print_r($_FILES);
        //exit;
        copy($_FILES["image1"]["tmp_name"],"upload/".$_FILES["image1"]["name"]);
        copy($_FILES["image2"]["tmp_name"],"upload/".$_FILES["image2"]["name"]);
        copy($_FILES["image3"]["tmp_name"],"upload/".$_FILES["image3"]["name"]);
        echo "Stored in: " . "upload/" . $_FILES["image1"]["name"];
        echo "<br>";
        echo "Stored in: " . "upload/" . $_FILES["image2"]["name"];
        echo "<br>";
        echo "Stored in: " . "upload/" . $_FILES["image3"]["name"];
    }
?>
<!doctype html>
<html lang="en">
   <head>
      <meta charset="utf-8">
      <title>demo</title>
   </head>
   <body>
      <form method="post" enctype="multipart/form-data"> 
         image 1 : <input type="file" name="image1" ><br/>
         image 2 : <input type="file" name="image2" ><br/>
         image 3 : <input type="file" name="image3" ><br/>
         <input type="submit" name="submit" value="Submit">
      </form>
   </body>
</html>

从下面这个数组我们可以看到这个在iphone / ipad中显示的图像名称对所有人来说是相同的，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
    )

好的，我找到了解决办法：）

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时添加rand（）或任何唯一的键名称文件夹中。

$image1 = rand().$_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);

多个图像上传在iphone和ipad中无效
