问题描述
我有写上载从相机拍摄到我的服务器映像的脚本。我得到的 200 OK 的反应，但我不认为我的形象我在上传服务器/文件夹：
也许我的脚本包含一个错误。你能帮助我吗？
我的例子是以下链接：<一href="http://androidexample.com/Upload_File_To_Server_-_Android_Example/index.php?view=article_discription&aid=83&aaid=106" rel="nofollow">http://androidexample.com/Upload_File_To_Server_-_Android_Example/index.php?view=article_discription&aid=83&aaid=106

这里是 PHP脚本：
＆LT; PHP
$ FILE_PATH =上传/;
$ FILE_PATH = $ FILE_PATH。基本名（$ _ FILES ['uploaded_file'] ['名称']）;
如果（move_uploaded_file（$ _ FILES ['uploaded_file'] ['tmp_name的值']，$ FILE_PATH））{
回声成功;
} 其他{
回声不及格;
}
？＆GT;
解决方案
你有没有验证的用户阿帕奇（或任何用户的PHP运行时）有写入权限在 $ FILE_PATH ？
将下面的code在同一目录下的PHP脚本，然后访问它的Web浏览器。
＆LT; PHP
$ FILE_PATH ='上传/';
$成功= file_put_contents（$ FILE_PATHå文件，这是一个测试）;
如果（$成功=== FALSE）{
回声无法写入文件;
} 其他 {
回声中写道$成功字节;
}
？＆GT;
这是否给一个成功的信息或错误信息？
如果它给出了一个错误信息，试图改变上传目录的所有权。

And here is the PHP script :
<?php
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
解决方案
Have you verified that the user apache (or whichever user php is running as) has permissions to write to the directory specified in $file_path?
Put the following code in the same directory as your PHP script is, and then visit it in your web browser.
<?php
$file_path = 'uploads/';
$success = file_put_contents($file_path . "afile", "This is a test");
if($success === false) {
echo "Couldn't write file";
} else {
echo "Wrote $success bytes";
}
?>
Does this give a success message or an error message?
If it gives an error message, trying changing the ownership of the uploads directory.
