Validation : URL (Simple)

Question

Is there a simpler way of validating an URL?

$website = test_input($_POST["website"]);

if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$website))
{
    $websiteErr = "Invalid URL"; 
}

You need a regular expression that conforms to these specifications : http://www.ietf.org/rfc/rfc1738.txt ... good luck with that. — CD001, Feb 20 '14 at 12:10

User the FILTER_VALIDATE_URL with the filter_var method:

filter_var docs: http://nl1.php.net/filter_var

filters you can use, including URL http://nl1.php.net/manual/en/filter.filters.validate.php

You may try this

/^HTTP|HTTPS|http(s)?:\/\/(www\.)?[A-Za-z0-9]+([\-\.]{1}[A-Za-z0-9]+)*\.[A-Za-z]{2,40}(:[0-9]{1,40})?(\/.*)?$/
