What are some common pitfalls or challenges when working with .ini files in PHP, and how can they be overcome?

Issue: One common challenge when working with .ini files in PHP is properly handling and parsing the data. It's important to correctly read and write the data in the .ini file to avoid errors. Solution: To overcome this challenge, you can use the built-in functions `parse_ini_file()` and `parse_ini_string()` in PHP to easily read and parse the .ini file data. 

// Read and parse data from .ini file
$ini_data = parse_ini_file('config.ini');

// Access specific values from the parsed data
$database_host = $ini_data['database']['host'];
$database_username = $ini_data['database']['username'];
$database_password = $ini_data['database']['password'];

// Modify existing values or add new ones
$ini_data['database']['password'] = 'new_password';

// Write the modified data back to the .ini file
$ini_string = '';
foreach ($ini_data as $section => $values) {
    $ini_string .= "[$section]\n";
    foreach ($values as $key => $value) {
        $ini_string .= "$key = $value\n";
    }
}

file_put_contents('config.ini', $ini_string);
