What are the best practices for deleting old files and databases before reinstalling a PHP forum like phpBB2?
When reinstalling a PHP forum like phpBB2, it is important to delete old files and databases to ensure a clean installation and prevent any conflicts or errors. To do this, you can manually delete the old files and drop the existing database tables before proceeding with the reinstall.
// Delete old files
$old_files = glob('/path/to/phpBB2/*');
foreach($old_files as $file){
if(is_file($file)){
unlink($file);
}
}
// Drop existing database tables
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "DROP DATABASE IF EXISTS $dbname";
if ($conn->query($sql) === TRUE) {
echo "Database dropped successfully";
} else {
echo "Error dropping database: " . $conn->error;
}
$conn->close();
