Question

我试图使用PHP将mp3格式文件上传到文件夹中。但是这个以下编码不起作用。请帮助我一个人吗？

define("UPLOAD_DIR", "mp3_upload_folder/");
if (!empty($_FILES["myFile"])) 
        {
        $myFile = $_FILES["myFile"];

        if ($myFile["error"] !== UPLOAD_ERR_OK) 
            {
            echo "<p>An error occurred.</p>";
            exit;
            }
     // verify the file is a GIF, JPEG, or PNG
    $fileType = exif_imagetype($_FILES["myFile"]["tmp_name"]);

        // ensure a safe filename
        $name = preg_replace("/[^A-Z0-9._-]/i", "_", $myFile["name"]);

        // don't overwrite an existing file
        $parts = pathinfo($name);

        $sanjiv=$_POST['user_id'];
        $name= $sanjiv.".".$parts["extension"];
        // preserve file from temporary directory
        $success = move_uploaded_file($myFile["tmp_name"],
            UPLOAD_DIR . $name);
        if (!$success) { 
            echo "<p>Unable to save file.</p>";
            exit;
        }

这样可行，并确保它具有写入mp3_upload_folder的权限。我认为它还缺乏一个完整的解决方案，但我对这个问题缺乏全面的了解。

<!DOCTYPE html>
<html>
<head>

</head>
<body>
<?php

define("UPLOAD_DIR", "./mp3_upload_folder/");
if (!empty($_FILES["myFile"])) {
    $myFile = $_FILES["myFile"];

    if ($myFile["error"] !== UPLOAD_ERR_OK) {
        echo "<p>An error occurred.</p>";
        exit;
    }

    // ensure a safe filename
    $name = $myFile["name"]; //preg_replace("/[^A-Z0-9\.\-]/i", "_", $myFile["name"]); //this is pointless if you're not using it

    // don't overwrite an existing file
    $parts = pathinfo($name);

    $name= $_POST['user_id'].".".$parts["extension"];
    // preserve file from temporary directory
    $success = move_uploaded_file($myFile["tmp_name"], UPLOAD_DIR .$name);
    if (!$success) { 
        echo "<p>Unable to save file.</p>";
        exit;
    }
}

?>
<form method="post" enctype="multipart/form-data">
    <input type="text" value="testUserId"  name ="user_id"/>
    <input type="file" name="myFile"/>
    <input type="submit"/>
</form>     

</body>
</html>

还要确保编辑服务器设置以及用于上传文件大小的php设置（在php.ini中）：

的post_max_size

Upload_max_size（可能是你的罪犯默认为2M）

我不确定您使用的服务器，但通过Google搜索服务器类型和“最大上传大小”可以轻松找到信息

将mp3文件上传到文件夹不起作用
