RE: [PHP] Regular expression - URL validator
Thanks again Jim,
That's what i really need.
I'm testing this function...
If i put a URL like www.example.com, then it works fine and turns it to
http://www.example.com
But if i put a URL like http://www.example.com, then it also put another
header so it turns to http://http://www.example.com
I also tried with the strstr function, but receive the same response.
Thanks in advance,
Wagner.

Thanks Jim,
Your sugestion worked perfect for me!!
I have another question:
After i validate this URL i want to put a link with this URL in my page.
The problem is that if the URL is like (www.aol.com), when i create the
link, this URL is appended with the URL of my site. The result is a link
pointing to: http://mywebsite/www.aol.com
But if the URL is like (http://aol.com), then the link is created correct.
Is there a way to avoid the first situation... so the link is created
correct?
Thanks again,

You could always do a string comparison for http(s)? in the url
if ( strpos($url, array('https://', 'http://')) === false ) {
$url = 'http://'.$url;
}

Give this a shot
plaintext?php
function fixurl($url) {
if ( !preg_match('!^(ftp|http(s)?)://!', $url) ) {
$url = 'http://'.$url;
}
return $url;
}
echo fixurl(www.google.com);
echo \n;
echo fixurl(ftp://www.google.com;);
echo \n;
echo fixurl(http://www.google.com;);
echo \n;
echo fixurl(https://www.google.com;);

Yes, make sure you have http:// on the front.
?php
if (strtolower(substr($link, 0, 7)) != 'http://') $link =
http://$link;;
?

It is basicaly an URL validator.

I think this is a PERL REGEX so what should i do to make it work in
php?
$valid =
(preg_match('^H|h)(T|t)|(F|f))(T|t)(P|p)((S|s)?))\://)?(www.|[a-zA-Z0-9]

+amp;%\$#\=~_\-]+))*$', $_POST['website']));
This should be preg_match('/.../i', $_POST['website'])
your regex should look something like this.
^((ftp|(http(s)?))://)?(\.?([a-z0-9-]+))+\.[a-z]{2,6}(:[0-9]{1,5})?(/[a-zA-Z
0-9.,;\?|\'+%\$#=~_-]+)*$
So, put it all together and it should look like this.
?php
$url = ...PUT YOUR TEST URL HERE...;
if (
preg_match('!^((ftp|(http(s)?))://)?(\.?([a-z0-9-]+))+\.[a-z]{2,6}(:[0-9]{1,
5})?(/[a-zA-Z0-9.,;\?|\'+%\$#=~_-]+)*$!i',
$url) ) {
echo Matched;
} else {
echo Did not match;
}
if ($valido == 0) {
something here;
}
else {
something else here;
}
Thanks a lot in advance,

you must use http://www.aol.com not www.aol.com. coz the later is not a
valid url. The protocol is not specified there. and if you use
www.aol.comis your href of a tags, the browser will automatically add
your current web
address as prefix as if its a relative url.
if your site is http://www.example.com/folder/site.html
and if you use href=/www.aol.com it will show http://www.example.com/
www.aol.com
if you use href=www.aol.com it will show
http://www.example.com/folder/http://www.aol.com/
www.aol.com
you have to use href=http://www.aol.com; the absolute one.
