a rfc compliant web address ?

[tommr]

I was getting help with my script and I just noticed this was added.

What does it mean?

 

 

/*** a rfc compliant web address ***/
$url = "http://www.phpro.org";

/*** try to validate the URL ***/
if(filter_var($url, FILTER_VALIDATE_URL) === FALSE)
        {
        /*** if there is no match ***/
        echo "Sorry, $url is not valid!";
        }
else
        {
        /*** if we match the pattern ***/
        echo "The URL, $url is valid!<br />";
        }

It's taking the URL in $url and validating it against a set of rules.  Look at filter_var() in the manual.

 

You're filter is FILTER_VALIDATE_URL

 

It's basically checking to make sure that the URL is formed correctly.
