How can error handling and reporting in PHP be utilized to troubleshoot issues with mysqli queries not working as expected?

When mysqli queries are not working as expected, error handling and reporting in PHP can be utilized to troubleshoot the issue. By enabling error reporting and checking for errors after executing queries, developers can identify the root cause of the problem and take appropriate actions to fix it. 

// Enable error reporting for mysqli queries
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

// Connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Execute the query
$query = "SELECT * FROM table";
$result = $mysqli->query($query);

// Check for errors
if (!$result) {
    echo "Error: " . $mysqli->error;
} else {
    // Process the query results
    while ($row = $result->fetch_assoc()) {
        // Output or manipulate the data
    }
}

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