Hi there,
I'm saving ip addresses of blocked visitors into a mySQL DB.
The function with wich i retrieve the address is below this message.
What i wonder is, if it's ok to remove the dots from the ip address,
and only
save the numbers into the database. I assume it will be quicker to
compare.
But i don't know if it could mess up ip addresses. E.g. confuse
12.34.56.78 with 123.45.6.78
Frizzle.
--- function ---
function getIp()
{
if ( isset( $_SERVER['HTTP_X_FORWARDED_FOR'] ) )
{
return $_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
return $_SERVER['REMOTE_ADDR'];
};
};
