How can users avoid the "Access denied" error when attempting to copy table content between databases in PHP?

When users encounter the "Access denied" error when attempting to copy table content between databases in PHP, it is likely due to insufficient permissions granted to the user for the source or destination database. To resolve this issue, users should ensure that the user has the necessary permissions to access and manipulate the tables in both databases. 

// Establish connection to source database
$source_connection = new mysqli("source_host", "source_username", "source_password", "source_database");

// Establish connection to destination database
$destination_connection = new mysqli("destination_host", "destination_username", "destination_password", "destination_database");

// Check if connections are successful
if ($source_connection->connect_error || $destination_connection->connect_error) {
    die("Connection failed: " . $source_connection->connect_error . " or " . $destination_connection->connect_error);
}

// Copy table content from source to destination database
$source_table = "source_table";
$destination_table = "destination_table";

$query = "INSERT INTO $destination_table SELECT * FROM $source_table";
if ($destination_connection->query($query) === TRUE) {
    echo "Table content copied successfully";
} else {
    echo "Error copying table content: " . $destination_connection->error;
}

// Close connections
$source_connection->close();
$destination_connection->close();
