I want to know how to check a url
if the format of the url is right not wrong
i want to check if the url contain:
xxx.xxx.(com,net,org,co,...).(us,uk,ue,kw,sa,...)
what i should do???
can anyone help me please
check a valid Url
preg_match('/^(http|ftp):\\/\\/([^.?]+.)+/',$string, $matches);
That will check the rough form of the url and place the protocol and domain into $matches[0]. I have to check through the TLD you will have to set up some alternation on the following list.

And we haven't even started on the second level domains. :eek: I would suggest that you need to be more certain of a url being correct than just it's form then ping it. Open up a socket to it and see of you get a response.

PS. Thank you very much , I 'd never bothered to actually look up all the TLDs before but it was quite interesting when I did. I also found this which I found rather intresting. 
can you please explain what you give me...
because i am tring to do this
preg_match('/^(http|ftp):\/\/([^.?]+.)+/',$string, $matches);
if(empty($matches))
echo "wrong url";
else
print_r($matches);
when i say string="http://www.php.net" , "http://php.net.sa","http://php.net"
it's work
when i say string="www.php.net" it's give me wrong Url
when i say string="http://ramez" it's work and print it( and this what i don't want)
"/^(http|ftp):\/\/([^.?]+\.)+\.)+/"
right, let's break it on down.
/ - this is the starting delimeter, this is the character it looks for to end the regex.
^ - This denotes the begining of the string
(http|ftp) - This is an alternation, it means that there must be either the string "http" or the string "ftp" (in this case, at the start of the string)
:\/\/ - matches :// the backslashes are added to escape the slashes so that the regex engine does not take either of them to be the closing delimiter for the regex
[.?]+ - One or more occurences (+) of any character other than . or ? ([.?])
. - matches a ., escaped because . is a special character matching any character.
+ - that whole bit we want repeated one or more times, always seperated by a dot.
To allow the string www.php.net you would have to say that the first part of the regex (concerning the protocol) is optional. You would do this by pernthesizing it and placing a question mark after it (optional).
/^((http|ftp):\/\/)?([^.?]+\.)+/

WTB, it CAN BE good URL for local network.
But if you want only common names with .com or something like:
... (?:[a-z0-9-]+.)+[a-z]{2,6}.?$
one or more subdomains and last part from 2 to 6 letters (it was from 2 to 3 in first version - damn on .info and .museum! )
