How to assign multiple values to a PHP variable?

Question

How do I go about assigning multiple values for a single variable in PHP?

I'm trying to do this

$IP = '111.111.111.111' || '222.222.222.222' || '333.333.333.333';

if ($_SERVER['REMOTE_ADDR'] != $IP) {
echo "Your IP is not on the list";

Is that even a proper way to do that?

Or should I put them in an array like this

$IP = array('111.111.111.111', '222.222.222.222', '333.333.333.333');

But then how would I go about checking if the $_SERVER['REMOTE_ADDR'] is one of the values inside the array?

Thanks

Yes, you should put it in array an use in_array() function instead of != operator:

if (!in_array($_SERVER['REMOTE_ADDR'], $IP))

this is what you're looking for

/** my own array preference **/
$allowedIPS = [ '111.111.111.111', '222.222.222.222', '333.333.333.333' ];

/** alternate syntax **/
$allowedIPS = array ( '111.111.111.111', '222.222.222.222', '333.333.333.333' );

if (false === in_array($_SERVER['REMOTE_ADDR'], $allowedIPS)) {
    echo "Your IP is not on the list";
}

thanks. these [ ] surrounding the IP's causes dreamweaver to give a syntax error.

Dreamweaver probably doesn't understand that array syntax, I added the alternate version in my edit.

Thank you for your help. How could I tell it to match only the first part of the IP address instead of the entire IP? For instance, if the IP is 111.111.111.111 but will match the entire range of 111.111.111.xxx. or 111.111.xxx.xxx
