如何在 PHP 中上传文件到 /upload 文件夹？

Question

<?php
if($_SERVER["REQUEST_METHOD"] == "GET"){
    $file = $_GET["fname"];
}else{
    if(isset($_POST["content"]) && isset($_POST["file"])){
          $folder = "/uploads/";
          $file = $_POST["file"];
          $content = $_POST["content"];
          if(file_exists($file)){
               echo "<h1>That file already exists on the server</h1>";
          }else{
               file_put_contents(basename($folder, $file), $content);

          }
          
     }else{
     echo "<h1>Request has failed to be sent</h1>";
    }

}

我使用 file_put_contents 因为我认为我可以将文件放在那里等等。

<?php
if ($_SERVER["REQUEST_METHOD"] == "GET") {
    $file = $_GET["fname"];
} else {
    if (isset($_POST["content"]) && isset($_POST["file"])) {
        $folder = __DIR__ . "/uploads/";
        $file = basename($_POST["file"]);
        $content = $_POST["content"];

        $filePath = $folder . $file;

        if (file_exists($filePath)) {
            echo "<h1>That file already exists on the server</h1>";
        } else {
            if (!is_dir($folder)) {
                mkdir($folder, 0777, true);
            }

            if (file_put_contents($filePath, $content) !== false) {
                echo "<h1>File successfully created</h1>";
            } else {
                echo "<h1>Failed to save file</h1>";
            }
        }
    } else {
        echo "<h1>Request has failed to be sent</h1>";
    }
}
?>

此代码应该执行上传。
