What could be causing only the first record to be inserted into the MySQL database in this PHP code?

The issue could be caused by not properly preparing the SQL statement before executing it in the loop. To solve this issue, you should move the preparation of the SQL statement outside of the loop and bind the parameters inside the loop before executing the statement. 

// Prepare the SQL statement outside of the loop
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");

foreach ($data as $row) {
    // Bind the parameters inside the loop
    $stmt->bindParam(':value1', $row['value1']);
    $stmt->bindParam(':value2', $row['value2']);
    
    // Execute the statement for each row
    $stmt->execute();
}
