What are the potential reasons for a PHP script not displaying any error messages when executing a MySQL query, and how can this issue be resolved?

The potential reasons for a PHP script not displaying any error messages when executing a MySQL query could be that error reporting is disabled, error reporting level is set to not display MySQL errors, or the error messages are being suppressed. To resolve this issue, you can enable error reporting for MySQL errors by setting the error reporting level appropriately and checking for errors after executing the query. 

// Enable error reporting for MySQL errors
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 result
}

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