How can PHP be used to dynamically adjust default values based on user input or application requirements in database operations?

When performing database operations in PHP, it is common to have default values for certain fields. However, these default values may need to be dynamically adjusted based on user input or application requirements. This can be achieved by checking the user input or application logic and setting the default values accordingly before executing the database operation. 

// Example of dynamically adjusting default values based on user input in database operations

// User input
$userInput = $_POST['user_input'];

// Default values
$defaultField1 = 'default_value1';
$defaultField2 = 'default_value2';

// Adjust default values based on user input
if ($userInput == 'condition1') {
    $defaultField1 = 'adjusted_value1';
} elseif ($userInput == 'condition2') {
    $defaultField2 = 'adjusted_value2';
}

// Use the adjusted default values in database operations
$query = "INSERT INTO table_name (field1, field2) VALUES ('$defaultField1', '$defaultField2')";
// Execute the query and perform other database operations
