Question

我现在已经在这里待了大约4个小时了。我已经尝试了几个我会在问题后解释的事情。

我从JPG中获得了所有这些EXIF数据（如下所列）

我要做的是将JPG重新保存到具有新名称的其他文件夹中。剥离“GCM_TAG”后，该新名称应该是$ data [“EXIF”] [“UserComment”]。这是在拍摄照片之前在仓库扫描的条形码。

我没有收到任何错误，我没有收到任何警告，但图像从未显示出来。如果我将代码更改为不包含$ barcode，则突然显示图像。我试过打印$ barcode，我试过检查变量的编码是什么，我试过使用fopen（），file_put_contents（）和copy（）都无济于事。每个人都有相同的结果。该文件夹有777权限，我可以使用PHP添加/删除文件就好了，并在此代码中测试了。任何帮助将不胜感激。

chdir("../test_import_photos");
$directory = getcwd();

echo __FILE__;
print "<br />";
print $directory;
if ($dirhandle = opendir($directory))
{
    while (false !== ($entry = readdir($dirhandle)))
    {
        if($entry == "." || $entry == "..")
        {
            //ignore, its just the folder commands
        }
        else
        {
            $data = exif_read_data($entry,"ANY_TAG",true,false);
            //print "2";
            //print "3";

            $barcode = str_replace("GCM_TAG","",$data["EXIF"]["UserComment"]);

            $filepath = "../test_import_photos_end/X" . $barcode .  ".JPG";
            copy($entry, $filepath);
        }
    }
    closedir($dirhandle);
}

Answer 1

我看到文件名出错（二进制数据可能会破坏数组（））而copy（）只会抛出一条E_WARNING消息，必须添加到error_reporting（E_ALL）;或error_reporting（E_WARNING）;看到它。

使用EXIF Data PHP时无法复制JPG
