Hi again,
I have function using regular expression in php, to read URL address
and process it, the sample of URl address is like this :
mail1.plasa.com --------------> the result -->mail1.plasa.com
mail.yahoo.com --------------> the result -->mail.yahoo.com
us.f416.mail.yahoo.com -------> the result -->mail1.yahoo.com
login.mail.eudoramail.com ----> the result -->mail1.mail.eudoramail.com
images.google.com ------------> the result -->google.com
us.i1.yimg.com ---------------> the result -->yimg.com
212.213.255.72 ---------------> the result -->212.213.255.72
mail.telkom.net --------------> the result -->mail.telkom.net
May be somthing wrong, when i input the url "mail.telkom.net" or
"mail1.plasa.com" the result not like i want it, may be you can help me to
check what's going on.
the function is like this :
function url_address($url){
$pattern1 = "/[0-9]$/"; // to check if the url is IP address
$pattern2 = "(mail|mail1)"; // to check if the url have string mail
or mail1
if (ereg($pattern2, $url)){
// take URL address if the url address is mail.yahoo.com or
mail.hotmail.com or mail1.plasa.com
$www_url = ereg
("([[:alnum:]]+)\.([[:alnum:]]+)\.([[:alnum:]]+)\.([[:alnum:]]+)\.(com|net|org|edu|mil|gov|gob|info|tv|biz|dk|za)",
$url,$regs);
echo "Alamat URL Asli $url<br>";
echo "array ke 0 $regs[0]<br>";
echo "array ke 1 $regs[1]<br>";
echo "array ke 2 $regs[2]<br>";
echo "array ke 3 $regs[3]<br>";
echo "array ke 4 $regs[0]<br>";
echo "array ke 5 $regs[1]<br>";
$fix_url="$regs[3].$regs[4].$regs[5]";
}
elseif(preg_match($pattern1, $url)){
// take the URL address if the url address is IP address (ex;
122.123.123.123)
echo "Alamat URL Asli $url<br>";
$fix_url=$url;
}
else{
// take URL address if the url address is
www.XXXX.com|net|org|edu|mil|gov|gob|info|tv|biz
$www_url = ereg("^(www)\.([[:alnum:]]+)\.([[:alnum:]]+)", $url,
$regs);
if ($www_url):
echo "Alamat URL Asli $url<br>";
$fix_url="$regs[2].$regs[3]";// www dibuang dan diambil nama.domain
else:
// take URL address if the url address is
www.YYYY.XXXX.com|net|org|edu|mil|gov|gob|info|tv|biz
echo "Alamat URL Asli $url<br>";
$www_url =
ereg("([[:alnum:]]+)\.(com|net|org|edu|mil|gov|gob|info|tv|biz|dk|za)", $url, $regs);
$fix_url="$regs[0]";
endif;
}
return $fix_url;
}
