How can multi-line comments in PHP code be effectively processed and extracted for documentation purposes using PHP functions like explode and regex?

To process and extract multi-line comments in PHP code for documentation purposes, you can use a combination of PHP functions like explode and regex. First, you can explode the code by new lines to separate each line of code. Then, you can use regex to identify and extract multi-line comments based on their opening and closing tags. This allows you to effectively extract the comments for documentation purposes. 

$code = file_get_contents('your_php_file.php');
$lines = explode("\n", $code);

$comments = [];
$inComment = false;
$currentComment = '';

foreach ($lines as $line) {
    if (preg_match('/\/\*(.*?)\*\//s', $line, $matches)) {
        $comments[] = $matches[1];
    } elseif (preg_match('/\/\*(.*)/', $line)) {
        $inComment = true;
        $currentComment = substr($line, strpos($line, '/*') + 2);
    } elseif ($inComment) {
        $currentComment .= $line;
        if (strpos($line, '*/') !== false) {
            $comments[] = $currentComment;
            $inComment = false;
        }
    }
}

print_r($comments);
