Are there any best practices for handling multi-line text extraction using regular expressions in PHP?

When extracting multi-line text using regular expressions in PHP, it's important to use the `s` flag to ensure that the dot `.` matches newline characters as well. Additionally, using the `preg_match_all()` function with the appropriate regular expression pattern can help extract all occurrences of the multi-line text. 

$text = "This is a multi-line
text example
for extracting using regex.";

preg_match_all('/This is a multi-line(.*?)using regex/s', $text, $matches);

print_r($matches[1]);
