Thanks in advance, Please Help

 

eregi is deprecated as of PHP 5.3

use preg_match instead. Shouldn't be that hard to rewrite.

Can you please Re-Write the Code for me with the change of eregi to preg-match,
please let me know how it should be to work,
as i had several trials but failed to put it working properly
Thanks

 

I think you should be able to do it yourself

 

If Im able to do it myself,
I wouldnt asking for help in this forum,
anyways thank you, i think that i will get more help from someone who appreciate helping others
Thanks !!!

 

You know the proverb: Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime.

I'll throw in a good PHP tutorial

http://devzone.zend.com/6/php-101-php-for-the-absolute-beginner/
http://tut.php-quake.net/en/post.html

Code (markup):

and a regular expression tutorial

http://www.zytrax.com/tech/web/regex.htm

Code (markup):

With these you should be able to fish

 

If you read the documentation for preg_match, there shouldn't have much difference.

It should look something like this in preg_match:

        if(!preg_match('/^[a-zA-Z0-9\-]{1,}$/', $domain))  return false;
        if(preg_match('/[-]{2,}/', $domain))               return false;
        if(preg_match('/^[-]{1,}/', $domain))              return false;
        if(preg_match('/[-]{1,}$/', $domain))              return false;
