How can one effectively handle multiple tables with similar names in a MySQL database when using PHP?

When dealing with multiple tables with similar names in a MySQL database, one effective way to handle this is by dynamically generating the table names based on a variable or parameter. This can be done by concatenating the variable with the table name in the SQL query to ensure the correct table is being accessed. By using this approach, you can easily switch between different tables without having to modify the query each time. 

<?php

// Define the variable for the table name
$tableName = "users";

// Connect to the MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Dynamically generate the table name in the SQL query
$sql = "SELECT * FROM " . $tableName;

$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();

?>
