I have a list of IP ranges like
$whitelist=array('50*','202.16*','123.168*',');
I want to block all other traffic from seeing the page.
I've tried
if(in_array($_SERVER['REMOTE_ADDR'],$whitelist)){
//display page
}

in_array
doesn't use regexs to compare. Also your regex is incorrect the *
is a quantifier. That allows zero or more of the previous character.
Try:
$whitelist=array('50\..*','202\.16\..*','123\.168\..*');
if(preg_match('/^(' . implode('|', $whitelist) . ')/', $_SERVER['REMOTE_ADDR'])){
The .*
is allowing anything (pretty much(see s
modifier http://php.net/manual/en/reference.pcre.pattern.modifiers.php), .
is any character and then paired with that quantifier previously mentioned).
The ^
is the start of the string.\.
is a literal .
.
The |
is an or.
