How can PHPAdmin be used to troubleshoot and validate the results of PHP queries?

PHPAdmin can be used to troubleshoot and validate the results of PHP queries by allowing you to directly run SQL queries on your database and see the results. You can use PHPAdmin to check if your PHP queries are returning the expected results, troubleshoot any errors in your SQL syntax, and verify the data being retrieved from the database.

// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

// Run SQL query
$sql = "SELECT * FROM table_name";
$result = $conn->query($sql);

// Display results
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Column1: " . $row["column1"]. " - Column2: " . $row["column2"]. "<br>";
    }
} else {
    echo "0 results";
}

// Close connection
$conn->close();
