If opt is given, returns its value. Otherwise, returns an associative array with the following elements (which correspond to opt), or FALSE on failure:

  • "url"
  • "content_type"
  • "http_code"
  • "header_size"
  • "request_size"
  • "filetime"
  • "ssl_verify_result"
  • "redirect_count"
  • "total_time"
  • "namelookup_time"
  • "connect_time"
  • "pretransfer_time"
  • "size_upload"
  • "size_download"
