我已经建立了一个网站，该网站允许图片上传，一旦图像被上传，则显示照片的某些特定信息。 从电脑上传图片的作品就好了，问题就来了，当我试图从智能手机上传图片。 上传成功，但它似乎是从计算机上传现在下落不明时所显示的数据的重要组成部分。
该代码部分是实际检索和显示的数据的一个：
$location = $_FILES["pic"]["tmp_name"];
$data = exif_read_data($location);
var_dump($data);
在var_dump($data)实际转储电脑和智能手机不同的数据。
编辑：显然，它的工作原理只是Andoroid智能手机很好，当我尝试上传iPhone图片的问题只出现
例如， var_dump从计算机上传：

var_dump从智能手机上传：
array(12) {

下面是计算机 var_dump($_FILES)
array(1)
{ ["pic"]=> array(5)
{ ["name"]=> string(18) leaf2.JPG"
["type"]=> string(10) "image/jpeg"
["tmp_name"]=> string(14) "/tmp/phpzeDUs9"
["error"]=> int(0)
["size"]=> int(46439) } }
下面是iPhone的结果var_dump($_FILES)
array(1) { ["pic"]=> array(5)
{ ["name"]=> string(9) "image.jpg"
["type"]=> string(10) "image/jpeg"
["tmp_name"]=> string(14) "/tmp/phplPUZky"
["error"]=> int(0) ["size"]=> int(1455577) } }
编辑：这是形式上传的HTML代码：
<form action="results.php" id="upload-image" method="post" enctype="multipart/form-data">
<div class="fileupload fileupload-new" data-provides="fileupload">
<div class="fileupload-preview thumbnail" style="width: 200px; height: 150px;"></div>
<div>
<span class="btn btn-file"><span class="fileupload-new">Select image</span><span class="fileupload-exists">Change</span><input type="file" name="pic" id="pic" accept="image/*"/></span>
<a href="#" class="btn fileupload-exists" data-dismiss="fileupload">Remove</a>
<button type="submit" class="btn">Upload</button>
</br>
<span class="upload-error"></span>
</div>
</form>
什么可能造成的吗？
