What potential error could be occurring when trying to create a table in a MySQL database using PHP?

One potential error that could occur when trying to create a table in a MySQL database using PHP is not establishing a connection to the database before executing the CREATE TABLE query. To solve this issue, you need to first establish a connection to the MySQL database using functions like mysqli_connect or PDO. 

<?php
// Establishing a connection to the MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

$conn = mysqli_connect($servername, $username, $password, $dbname);

// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

// Creating a table in the database
$sql = "CREATE TABLE table_name (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    column1 VARCHAR(30) NOT NULL,
    column2 VARCHAR(30) NOT NULL
)";

if (mysqli_query($conn, $sql)) {
    echo "Table created successfully";
} else {
    echo "Error creating table: " . mysqli_error($conn);
}

// Close connection
mysqli_close($conn);
?>
