    If you're reusing a cUrl handle and want to ensure there's no residue from previous options -- but are frustrated with resetting the basics (e.g. FTP details) needed for each cURL call -- then here's an easy pattern to fix that:

    <?php
    class cUrlicue {
       
        protected     $curl;

            /* Create the cURL handle */

            function __construct() {
                $this->curl = curl_init();
                $this->curl_init_opts();
                curl_exec($this->curl);
        }
       
            /* Reload your base options */

            function curl_init_opts() {
                $opts[CURLOPT_PROTOCOLS]         = CURLPROTO_FTP;
                $opts[CURLOPT_RETURNTRANSFER]     = true;
                $opts[CURLOPT_USERPWD]             = 'user:pass';
                //...
                curl_setopt_array($this->curl, $opts);
        }
       
            /* Use when making a new cURL call */

            function curl_exec($opts) {
                curl_reset($this->curl); // clears all old options
                $this->curl_init_opts(); // sets base options again
                curl_setopt_array($this->curl, $opts); // sets your new options
                return curl_exec($this->curl);
        }
       
            /* Your whatever cURL method */

            function curl_get_whatever() {
                $opts[CURLOPT_URL] = 'ftp://.../whatever';
                //...
                $result = $this->curl_exec($opts);
                // ...
            }   
    }
    ?>

    Then: each call to $this->curl_exec() from your whatever-method resets the previous options, reloads the base options, adds in your new options, and returns the result. Otherwise, can also put your base options into a class property, instead of in-method, if there's nothing dynamic being defined. Enjoy. =^_^=
