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. =^_^=
