How can PHP code be modified to successfully update values in a configuration file like config.inc.php based on user input from a form?

To update values in a configuration file like config.inc.php based on user input from a form, you can use PHP to read the form input, modify the configuration file, and write the updated values back to the file. This can be achieved by opening the configuration file, parsing its contents to locate the values that need to be updated, making the changes, and then saving the file with the updated values. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $newConfigValue = $_POST['new_config_value'];

    $configFile = 'config.inc.php';
    $configContent = file_get_contents($configFile);

    // Modify the configuration value based on user input
    $updatedConfigContent = preg_replace('/\$configValue = \'(.*)\';/', "\$configValue = '$newConfigValue';", $configContent);

    file_put_contents($configFile, $updatedConfigContent);
}
?>
