What is the best way to dump multiple tables with a specific prefix in PHP?

When you need to dump multiple tables with a specific prefix in PHP, you can use a MySQL query to get a list of tables with the desired prefix and then loop through each table to dump its contents. This can be achieved by querying the information_schema database to retrieve the table names that match the prefix, and then using a foreach loop to dump the data from each table. 

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";
$prefix = "prefix_";

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

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

// Get list of tables with specific prefix
$sql = "SELECT table_name FROM information_schema.tables WHERE table_schema = '$dbname' AND table_name LIKE '$prefix%'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        $table = $row["table_name"];
        $dump_sql = "SELECT * FROM $table";
        $dump_result = $conn->query($dump_sql);

        if ($dump_result->num_rows > 0) {
            // Output data of each row
            while($dump_row = $dump_result->fetch_assoc()) {
                // Do something with the data, like echo or save to a file
                print_r($dump_row);
            }
        } else {
            echo "0 results for table $table";
        }
    }
} else {
    echo "0 results for tables with prefix $prefix";
}

$conn->close();
?>
