What are some common issues or challenges that users face when using ftp_chmod()?

One common issue users face when using ftp_chmod() is incorrect file permissions being set, leading to access or security issues. To solve this, users should ensure they are using the correct numerical value for the permissions they want to set.

// Example code to set correct file permissions using ftp_chmod()
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';
$ftp_conn = ftp_connect($ftp_server);
$ftp_login = ftp_login($ftp_conn, $ftp_user, $ftp_pass);

// Set correct file permissions (e.g., 0644 for read/write for owner, read for group and others)
ftp_chmod($ftp_conn, 0644, 'example.txt');

// Close FTP connection
ftp_close($ftp_conn);
