Get size of POST-request in PHP

php, post, size

Solution

As simple as:

$size = (int) $_SERVER['CONTENT_LENGTH'];

Note that `$_SERVER['CONTENT_LENGTH']` is only set when the HTTP request method is POST (not GET). This is the raw value of the `Content-Length` header, as specified in RFC 7230.

In the case of file uploads, if you want to get the total size of uploaded files, you should iterate over the `$_FILE` array to sum each `$file['size']`. The exact total size might not match the raw `Content-Length` value due to the encoding overhead of the POST data. (Also note you should check for upload errors using the `$file['error']` code of each `$_FILES` element, such as `UPLOAD_ERR_PARTIAL` for partial uploads or `UPLOAD_ERR_NO_FILE` for empty uploads. See file upload errors documentation in the PHP manual.)
