What are the potential issues with variable initialization and string offsets when parsing CSV data for HTML table display in PHP?

When parsing CSV data for HTML table display in PHP, potential issues with variable initialization can arise if variables are not properly initialized before being used. Similarly, string offsets may cause problems if not handled carefully, leading to errors or unexpected behavior in the table display. To solve these issues, ensure that variables are initialized before use and carefully handle string offsets to avoid any parsing errors. 

<?php

// Sample CSV data
$csv_data = "Name,Age,Location\nJohn,25,New York\nJane,30,Los Angeles";

// Parse CSV data and display in HTML table
$rows = explode("\n", $csv_data);
echo "<table>";
foreach ($rows as $row) {
    $cells = explode(",", $row);
    echo "<tr>";
    foreach ($cells as $cell) {
        echo "<td>" . htmlspecialchars($cell) . "</td>";
    }
    echo "</tr>";
}
echo "</table>";

?>
