How can the use of regular expressions be improved in a template script to avoid potential syntax errors and improve maintainability?

Regular expressions can be improved in a template script by using single quotes for the regex pattern to avoid potential syntax errors caused by special characters in the pattern. Additionally, using the PHP `preg_quote` function can help escape any special characters in the input string before using it in the regular expression, improving maintainability. 

// Example of using single quotes and preg_quote to improve regular expressions in a template script
$input_string = 'This is a sample input with special characters: $^*';
$pattern = '/'.preg_quote('$^*', '/').'/';

if (preg_match($pattern, $input_string)) {
    echo 'Pattern found in input string';
} else {
    echo 'Pattern not found in input string';
}
