The ftp_chdir() function is an inbuilt function in PHP which is used to change the current directory on the FTP server.

Syntax:

ftp_chdir( $ftp_connection, $directory )

Parameter: This function accepts two parameters as mentioned above and described below:  

• $ftp_connection: It is required parameter. It specifies the already existing FTP connection to use for execution of FTP commands or functions.
• $directory: It is required parameter. It specifies the path in remote server to which current directory to be changed.

Return Value: It returns True on success or False on failure.
Note:

• This function is available for PHP 4.0.0 and newer version.
• The following examples cannot be run on online IDE. So try to run in some PHP hosting server or localhost with a proper ftp server name, user and password.
• Make sure you have permission to change directory and access to the directory.

Example:

php

<?php

// Connect to FTP server

// Use a correct ftp server
$ftp_server = "localhost";

// Use correct ftp username
$ftp_username="username";

// Use correct ftp password corresponding
// to the ftp username
$ftp_userpass="password";

// Establishing ftp connection
$ftp_connection = ftp_connect($ftp_server)
        or die("Could not connect to $ftp_server");

if($ftp_connection) {
    echo "successfully connected to the ftp server!";

    // Logging in to established connection with
    // ftp username password
    $login = ftp_login($ftp_connection, $ftp_username, $ftp_userpass);

    if($login) {

        // Checking whether logged in successfully or not
        echo "<br>logged in successfully!";

        // ftp_chdir() changing current directory to "htdocs"
        // remember, you must have folder that will use inside
        // current directory of ftp server.
        // Here htdocs folder exists in ftp server inside
        // base or root directory
        if (ftp_chdir($ftp_connection, "htdocs")) {
            echo "<br>Current directory successfully changed to htdocs.";
        }
        else {
            echo "<br>Error while changing current directory.";
        }
    }
    else {
        echo "<br>login failed!";
    }

    // Closing  connection
    if(ftp_close($ftp_connection)) {
        echo "<br>Connection closed Successfully!";
    }
}
?>

Output:

successfully connected to the ftp server!
logged in successfully!
Current directory successfully changed to htdocs.
Connection closed Successfully!
