How can PHP and SQL be integrated effectively to ensure all relevant data is displayed correctly?

To integrate PHP and SQL effectively to ensure all relevant data is displayed correctly, you can use PHP to connect to the database, execute SQL queries to retrieve the necessary data, and then use PHP to format and display the data on the webpage. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Execute SQL query to retrieve data
$sql = "SELECT * FROM table_name";
$result = $conn->query($sql);

// Display the data
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
