  <para>
   <function>ftp_ssl_connect</function> opens an <emphasis>explicit</emphasis> SSL-FTP connection to the
   specified <parameter>hostname</parameter>. That implies that
   <function>ftp_ssl_connect</function> will succeed even if the server is not
   configured for SSL-FTP, or its certificate is invalid. Only when
   <function>ftp_login</function> is called, the client will send the
   appropriate AUTH FTP command, so <function>ftp_login</function> will fail in
   the mentioned cases.
  </para>
  <note>
   <title>Why this function may not exist</title>
   <para>
    Before PHP 7.0.0, <function>ftp_ssl_connect</function> was only available if both
    the ftp module and the <link linkend="ref.openssl">OpenSSL</link>
    support have been built statically into php; this means that on Windows this
    function had been undefined in the official PHP builds. To have this
    function available on Windows, it had been necessary to compile own PHP binaries.
   </para>
  </note>
  <note>
   <para>
    <function>ftp_ssl_connect</function> is not intended for use with sFTP.
    To use sFTP with PHP, please see <function>ssh2_sftp</function>.
