What is the issue with deleting files via FTP after creating them in PHP?

When creating files in PHP and then trying to delete them via FTP, the issue often arises due to file permissions. The FTP server may not have the necessary permissions to delete files created by PHP. To solve this issue, you can set the correct permissions for the files when creating them in PHP, ensuring that the FTP server can delete them successfully. 

$file = 'example.txt';
$content = 'Hello, World!';

// Create the file with proper permissions
file_put_contents($file, $content);
chmod($file, 0644);

// Connect to FTP server and delete the file
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';

$ftp_conn = ftp_connect($ftp_server);
ftp_login($ftp_conn, $ftp_user, $ftp_pass);
ftp_delete($ftp_conn, $file);

// Close FTP connection
ftp_close($ftp_conn);
