Checking web address

[JordanTLClive]

I need to check that the web address a user inputs is VALID. It needs to have http://, https:// or whatever you may have there, followed by the website with no spaces. How can I do this?

Actually I need to check for a valid email address too.

Try doing a search for email validation on this forum.

As for the regular expression you need.

$url = "<br>[url]www.somedomain.com[/url]";

/*
This first one prints "has it" if the 
[url]http://[/url] or [url]https://[/url] is present
*/
print (eregi("(http|https)://", $url)) ? "has it<br>" : "doesn't have it<br>";

/*
This one prints "has spaces" if the 
domain has space in it.
*/
print (eregi("[[:space:]{1}]", $url)) ? "has spaces<br>" : "doesn't have spaces<br>";
