How can you handle special characters or symbols within strings when using PHP functions like explode or preg_split?

Special characters or symbols within strings can cause issues when using PHP functions like explode or preg_split because these functions may interpret the characters as delimiters or regex patterns. To handle special characters or symbols within strings, you can use the preg_quote function to escape the characters before using them in the functions. 

$string = "Hello, world! How are you?";
$delimiter = ",";
$escapedDelimiter = preg_quote($delimiter, '/');
$parts = preg_split('/' . $escapedDelimiter . '/', $string);

print_r($parts);
