上传文件时获取base64编码

Question

I am trying to get the base64 encoding for a file when uploading in PHP using:

$sound = base64_encode( file_get_contents( $_FILES["sound"]["tmp_name"] ) );

but it's returning:

Notice: file_get_contents(): send of 8192 bytes failed with errno=104 Connection reset by peer

Is it possible to do this without saving the file to the server?

Answer 1

It looks like the filename is too long. Please check the length of the string you are passing to file_get_contents:

echo strlen($_FILES["sound"]["tmp_name"]));

As far as I feel your server might be configured improperly. Maybe you need to check the temp path for file uploads if it's not too long.
