What are the potential reasons for the table not displaying correctly in the browser and how can this issue be debugged in PHP?

The potential reasons for the table not displaying correctly in the browser could be due to errors in the HTML markup, CSS styling, or PHP code that generates the table. To debug this issue in PHP, you can start by checking the HTML output generated by the PHP script to ensure that the table structure is correct. Additionally, you can inspect the CSS styles applied to the table elements to identify any styling issues that may be causing the display problem.

<?php
// Sample PHP code to generate a table with data
$data = array(
    array("John Doe", "30", "New York"),
    array("Jane Smith", "25", "Los Angeles"),
    array("Michael Johnson", "35", "Chicago")
);

echo "<table>";
echo "<tr><th>Name</th><th>Age</th><th>City</th></tr>";
foreach ($data as $row) {
    echo "<tr>";
    foreach ($row as $cell) {
        echo "<td>{$cell}</td>";
    }
    echo "</tr>";
}
echo "</table>";
?>
