What could be causing the issue of the first row not being displayed in the PHP code provided?

The issue of the first row not being displayed in the PHP code provided could be due to the fact that the loop is starting from index 1 instead of index 0. To solve this issue, you can adjust the loop to start from index 0.

<?php
$students = array(
    array("Alice", "Smith", 24),
    array("Bob", "Johnson", 22),
    array("Charlie", "Brown", 21)
);

echo "<table border='1'>";
echo "<tr><th>First Name</th><th>Last Name</th><th>Age</th></tr>";

for ($i = 0; $i < count($students); $i++) {
    echo "<tr>";
    foreach ($students[$i] as $value) {
        echo "<td>" . $value . "</td>";
    }
    echo "</tr>";
}

echo "</table>";
?>
