Contact form in PHP website gives errors

[soft2050]

They are deprecated functions and they shouldn't be used since they are going to be removed in future versions.

Instead of eregi, use preg_match, replace code with:

{
        return preg_match("/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i", $email);
    } 

Same goes for the split function too, instead of that use explode function, replace with:

 $toArr = explode(',', $to);
