Question

i need to rewrite this function to be compatible with php 5.3

function fns_data($address)
{
if (ereg("^[a-zA-Z0-9_\.\-]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$", $address))
{return true;}
return false;
}

anyone can help?

In general, changing ereg to preg is (usually) as simple as renaming it to “preg_match” and adding a / to the start and end of the pattern. Since your pattern is (relatively) simple:

function fns_data($address) {
   if (preg_match('/^[a-zA-Z0-9_\.\-]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$/', $address)) {
       return true;
   }
   return false;
}
