How can errors related to parameter count be avoided when using mysqli_stmt::bind_param in PHP?

When using mysqli_stmt::bind_param in PHP, errors related to parameter count can be avoided by ensuring that the number of parameters passed to bind_param matches the number of placeholders in the SQL query. This can be achieved by counting the number of placeholders in the query and passing the corresponding number of parameters to bind_param. 

// Assuming $mysqli is a valid mysqli connection and $param1, $param2, $param3 are the parameters to bind
$query = "INSERT INTO table_name (column1, column2, column3) VALUES (?, ?, ?)";
$stmt = $mysqli->prepare($query);

// Check if the query was prepared successfully
if ($stmt) {
    // Bind the parameters based on the number of placeholders in the query
    $stmt->bind_param("sss", $param1, $param2, $param3);
    
    // Execute the statement
    $stmt->execute();
    
    // Close the statement
    $stmt->close();
} else {
    // Handle the case where the query preparation failed
    echo "Error preparing query: " . $mysqli->error;
}
