Are there any specific debugging techniques or resources recommended for troubleshooting PHP code that interacts with MySQL databases?

When troubleshooting PHP code that interacts with MySQL databases, it is recommended to enable error reporting in PHP to catch any syntax errors or warnings. Additionally, using functions like `mysqli_error()` can help identify database connection or query errors. Utilizing tools like phpMyAdmin or MySQL Workbench to visually inspect the database for any inconsistencies can also aid in debugging. 

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

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

$conn = mysqli_connect($servername, $username, $password, $dbname);

// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

// Query database
$sql = "SELECT * FROM table";
$result = mysqli_query($conn, $sql);

if (!$result) {
    echo "Error: " . mysqli_error($conn);
}

// Close connection
mysqli_close($conn);
?>
