curl_reset($ch);
// 发送 HTTP 请求

Hack for php < 5.5 : 
function curl_reset(&$ch){
 $ch = curl_init();
}

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. =^_^=
