How important is it to understand the fundamentals of PHP when working on projects like creating data tables for websites?

Understanding the fundamentals of PHP is crucial when working on projects like creating data tables for websites because PHP is commonly used for server-side scripting and interacting with databases. Knowing how to write PHP code allows developers to retrieve, manipulate, and display data in a tabular format on a website.

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

// Retrieve data from the database
$sql = "SELECT * FROM table_name";
$result = $conn->query($sql);

// Create a data table
echo "<table>";
echo "<tr><th>ID</th><th>Name</th><th>Email</th></tr>";
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "<tr><td>".$row["id"]."</td><td>".$row["name"]."</td><td>".$row["email"]."</td></tr>";
    }
} else {
    echo "<tr><td colspan='3'>No data found</td></tr>";
}
echo "</table>";

// Close the database connection
$conn->close();
?>
