How can the performance of database queries be optimized in PHP without creating separate tables for each event?

To optimize the performance of database queries in PHP without creating separate tables for each event, you can use indexing on the columns that are frequently used in your queries. By indexing these columns, you can speed up the retrieval of data from the database. Additionally, you can optimize your queries by using proper SQL syntax and avoiding unnecessary joins or subqueries. 

// Example of creating an index on a column in a MySQL database table
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

// Create index on 'event_date' column in 'events' table
$sql = "CREATE INDEX event_date_index ON events (event_date)";
if ($conn->query($sql) === TRUE) {
  echo "Index created successfully";
} else {
  echo "Error creating index: " . $conn->error;
}

// Close connection
$conn->close();
