Android：画像をPHPサーバーにアップロード

カメラから撮影した画像をサーバーにアップロードするスクリプトを作成しました。 200OKの応答がありますが、サーバーのuploads /フォルダーに画像が表示されません：

enter image description here

たぶん私のスクリプトにエラーが含まれています。私を手伝ってくれますか ？

            return serverResponseCode; 

        } // End else block 
    } 

}

そしてここにPHPスクリプトがあります：

<?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";
    }
 ?>

ユーザーApache（またはphpが実行されているユーザー）が$file_pathで指定されたディレクトリに書き込む権限を持っていることを確認しましたか？

次のコードをPHPスクリプトと同じディレクトリに配置し、Webブラウザでアクセスします。

<?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";
}

?>

これにより、成功メッセージまたはエラーメッセージが表示されますか？

エラーメッセージが表示される場合は、uploadsディレクトリの所有権を変更してみてください。
