What suggestions are provided by other forum users to improve the regular expression pattern for phone number validation in PHP?

The regular expression pattern for phone number validation in PHP may not be comprehensive enough to cover all possible phone number formats. To improve it, other forum users suggest including optional country codes, area codes, and different separators like dashes or spaces. This will make the pattern more flexible and able to validate a wider range of phone numbers. 

$phone_number = "+1-555-123-4567";

if (preg_match("/^\+?(\d{1,3})?[-. ]?\(?(\d{3})\)?[-. ]?(\d{3})[-. ]?(\d{4})$/", $phone_number)) {
    echo "Valid phone number.";
} else {
    echo "Invalid phone number.";
}
