$regex1 = '/pattern1/';
$regex2 = '/pattern2/';
$regex3 = '/pattern3/';

$combinedRegex = $regex1 . '|' . $regex2 . '|' . $regex3;

// Alternatively, you can use the implode function to combine an array of regex patterns
$regexArray = array($regex1, $regex2, $regex3);
$combinedRegex = '/' . implode('|', $regexArray) . '/';

// Then, you can use the combined regex pattern in preg_match or preg_match_all functions
if (preg_match($combinedRegex, $subject, $matches)) {
    // Do something with the matches
} else {
    // No match found
}
