All I need to do in PHP is:

READ the contents of a file on my FTP server. (Contents of file are only a single number, 0 - 12)
Add that to a $variable string
Change that $variable and re-write the contents to the same file I READ from.

I am currently READING the contents of the file and adding that to a $variable perfectly using this function:

$expire = "filename";

function read_file($expire)
        {
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, "ftp://"location"/".$expire);
            curl_setopt($curl, CURLOPT_USERPWD, "U:P");
            curl_setopt($curl, CURLOPT_HEADER, 0);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($curl, CURLOPT_FRESH_CONNECT, 1);
            curl_setopt($curl, CURLOPT_TIMEOUT, 20);
            $data = curl_exec($curl);
            curl_close($curl);
            if ($data != false){
                return $data;
                }else{
                echo 'ERROR';
               }
        }
            $content = read_file($expire);

As far as WRITING the $new_content variable back to the same file, I am completely lost on finding any examples of this....

My assumption would be:

$expire = "filename";
$content = $new_contents;

function write_file($expire)
           $curl = curl_init();

            curl_setopt($curl, CURLOPT_URL, "ftp://"location"/".$expire);

            curl_setopt($curl, CURLOPT_USERPWD, "U:P");

            curl_setopt($curl, CURLOPT_HEADER, 0);

            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

    //this is where I am completely lost...
            curl_setopt($curl, CURLOPT_WRITEFUNCTION, "$new_contents?");
            curl_setopt($curl, CURLOPT_WRITEDATA, "$new_contents?");
    //

            curl_setopt($curl, CURLOPT_FRESH_CONNECT, 1);

            curl_setopt($curl, CURLOPT_TIMEOUT, 20);

            $data = curl_exec($curl);

            curl_close($curl);

            if ($data != false){

                return $data;

                }else{

                echo 'ERROR';
                }

        }

I have read that cURL does NOT need the fopen, fwrite, fclose calls in order to write data to a file? And I have also read about the CURLOPT_WRITEFUNCTION call, and that is where I am not sure how to WRITE the new contents of the $new_contents variable???

A simple example on the cURL PHP example would be wonderful.

I apologize in advance for my lack of PHP or cURL knowledge. I am working on this project for a commercial business, and I am the smartest one employed here!!

Thanks in advance...
