What are the best practices for handling special characters like [] and "" in CSV parsing with PHP?

Special characters like [] and "" can cause issues when parsing CSV files in PHP. To handle these characters properly, it is recommended to use PHP's built-in functions like fgetcsv() or str_getcsv() with appropriate parameters to handle special characters. Additionally, using proper escaping techniques or libraries like PHP's built-in functions like addslashes() or mysqli_real_escape_string() can help prevent parsing errors. 

// Example code snippet for handling special characters in CSV parsing with PHP
$file = fopen('example.csv', 'r');
while (($data = fgetcsv($file, 0, ',', '"', '"')) !== false) {
    // Process the CSV data here
    foreach ($data as $value) {
        // Handle special characters like [] and ""
        $escaped_value = addslashes($value);
        // Further processing of the escaped value
    }
}
fclose($file);
