The mime type of mp3 is audio/mpegfor mp4 you have to use video/mp4and wave is audio/x-wavor audio/wav.
mp3 的 mime 类型audio/mpeg用于您必须使用的 mp4，video/mp4而 wave 是audio/x-wav或audio/wav。
Also you should increase the file size, because this argument is given in bytes and 1000000 is less than 1mb. Maybe you have also to increase the upload file size in php.ini
您还应该增加文件大小，因为此参数以字节为单位给出，而 1000000 小于 1mb。也许您还必须增加 php.ini 中的上传文件大小

There is an alternate way to validate a file, But it is a basic way to check the file validation not sure if file holds the correct type of not.
有一种验证文件的替代方法，但它是检查文件验证的基本方法，不确定文件是否包含正确的类型。
$valid_extension = array('.mp3', '.mp4', '.wav');
$file_extension = strtolower( strrchr( $_FILES["file"]["name"], "." ) );
if( in_array( $file_extension, $valid_extension ) &&
$_FILES["file"]["size"] < 1000000 ){
// Rest Logic Here
}
else
{
print_r( $_FILES );
}
Note:
笔记：
这是一个基本的文件验证。回答by De-Coder
You are missing an if clause :
您缺少一个 if 子句：
if(isset($_POST['name_submit_button']))
{
//Whole Logic of program
}
