What are the drawbacks of defining a large number of variables for PHP code embedded within HTML?

Defining a large number of variables within PHP code embedded within HTML can make the code harder to read and maintain. It can also lead to potential naming conflicts and make debugging more challenging. To solve this issue, it's recommended to limit the number of variables defined within the HTML and instead use PHP functions and arrays to organize and manage data more efficiently.

<?php

// Define an array to store variables
$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'city' => 'New York'
);

// Access variables using array keys in HTML
?>

<p>Name: <?php echo $data['name']; ?></p>
<p>Age: <?php echo $data['age']; ?></p>
<p>City: <?php echo $data['city']; ?></p>
