Domain "Extension" Array

[orionellis]

Please correct me.

I want to take input from $_POST['website'] and put it in a variable, then I want to check whether or not one of these domain extensions were entered (of course there are more than 6 extensions, but this is for testing). Is there a better way of doing this or am I on the right path?

 

//validate website posted. Domain was entered.
$website = $_POST['website'];
$domains = array("com", "net", "org", "edu", "us", "biz");
if (!in_array($website, $domains)) {
$error .= "<p class='error'>Enter the web address in the correct format.</p>";
}

<?php
$url="http://www.google.co.uk";
if(eregi("^(http://|https://|ftp://|
http://www.)+[a-z0-9\_\-]{1,25}\.+
([a-z0-9\_\-]{1,3}|.+[a-z0-9\_\-]{1,3}\.
+[a-z0-9\_\-]{1,3})$", $url)
){
echo" your url is: $url";
}else{
echo"sorry wrong url: $url format";
}
?>
