PHP ftp_ssl_connect() Function

The PHP ftp_ssl_connect() function opens an explicit secure SSL-FTP connection to the specified hostname. This function will succeed even if the server is not configured for SSL-FTP, or its certificate is invalid.

Note: Before PHP 7.0.0, this function was only available if both the ftp module and the OpenSSL support have been built statically into PHP.

Syntax

ftp_ssl_connect(hostname, port, timeout)

Parameters

`hostname`	`Required.` Specify the FTP server address. This parameter should not be prefixed with ftp:// or contain any trailing slashes.
`port`	`Optional.` Specify an alternate port to connect to. If it is omitted or set to zero, then the default FTP port, 21, will be used.
`timeout`	`Optional.` Specify the timeout in seconds for all subsequent network operations. Default is 90 seconds. The timeout can be changed and queried at any time with ftp_set_option() and ftp_get_option().

Return Value

Returns a SSL-FTP stream on success or false on error.

Example:

The example below shows the usage of ftp_ssl_connect() function.

<?php
//FTP server to use
$ftp_server = "ftp.example.com";

//username for the FTP Connection
$ftp_user = "user";
  
//password for the user
$ftp_pass = "password";

//set up a SSL-FTP connection
$ftp = ftp_ssl_connect($ftp_server);
   
if($ftp) {
  echo "Successfully connected to $ftp_server!\n";
 
  //trying to login
  if(@ftp_login($ftp, $ftp_user, $ftp_pass)) {
    echo "Connected as $ftp_user@$ftp_server\n";
  } else {
    echo "Couldn't connect as $ftp_user\n";
  }

  //close the connection
  if(ftp_close($ftp)) {
    echo "Connection closed successfully!\n"; 
  } 
}
?>

The output of the above code will be:

Successfully connected to ftp.example.com!
Connected as user@ftp.example.com
Connection closed successfully!
