How can PHP developers effectively handle duplicate user names in a multidimensional array when displaying tabular data on a website?

When displaying tabular data on a website, PHP developers can handle duplicate user names in a multidimensional array by using a unique identifier for each user, such as an ID or username. They can then iterate through the array and create a new associative array where the keys are the unique identifiers and the values are the user data. This way, duplicate user names can be effectively managed and displayed in the table without any conflicts. 

<?php
// Sample multidimensional array with duplicate user names
$users = [
    ['id' => 1, 'name' => 'John Doe', 'email' => 'john@example.com'],
    ['id' => 2, 'name' => 'Jane Smith', 'email' => 'jane@example.com'],
    ['id' => 3, 'name' => 'John Doe', 'email' => 'johndoe@example.com'],
];

// Create a new associative array with unique identifiers as keys
$newUsers = [];
foreach ($users as $user) {
    $newUsers[$user['id']] = $user;
}

// Display tabular data
echo '<table>';
echo '<tr><th>ID</th><th>Name</th><th>Email</th></tr>';
foreach ($newUsers as $user) {
    echo '<tr>';
    echo '<td>' . $user['id'] . '</td>';
    echo '<td>' . $user['name'] . '</td>';
    echo '<td>' . $user['email'] . '</td>';
    echo '</tr>';
}
echo '</table>';
?>
