有没有更快的方法来检查PHP块的IP

Question

With my continued battle of blocking spammers from Nigeria I've blocked the country code in my htaccess file using GeoIP but some still manage to get through. To add another layer I want to iterate through the following list of IP ranges from Nigeria and block them:

41.75.192.0 41.75.207.255
41.138.160.0    41.138.191.255
41.139.64.0 41.139.127.255  
41.155.0.0  41.155.127.255
41.184.0.0  41.184.255.255
41.189.0.0  41.189.31.255
41.190.0.0  41.190.31.255
41.203.64.0 41.203.95.255
41.203.96.0 41.203.127.255
41.204.224.0    41.204.255.255
41.205.160.0    41.205.191.255
41.206.0.0  41.206.31.255
41.206.224.0    41.206.255.255
41.211.192.0    41.211.255.255
41.216.160.0    41.216.175.255
41.217.0.0  41.217.127.255
41.219.128.0    41.219.191.255
41.219.192.0    41.219.255.255
41.220.64.0 41.220.79.255
41.221.112.0    41.221.127.255
41.221.160.0    41.221.175.255
62.173.32.0 62.173.63.255
62.193.160.0    62.193.191.255
80.248.0.0  80.248.15.255
80.250.32.0 80.250.47.255
81.18.32.0  81.18.47.255
82.128.0.0  82.128.127.255
195.166.224.0   195.166.255.255 
196.1.176.0 196.1.191.255
196.29.208.0    196.29.223.255
196.45.48.0 196.45.63.255
196.45.192.0    196.45.255.255  
196.200.0.0 196.200.15.255
196.200.64.0    196.200.79.255
196.200.112.0   196.200.127.255 
196.207.0.0 196.207.15.255
196.220.0.0 196.220.31.255
212.100.64.0    212.100.95.255
217.14.80.0 217.14.95.255
217.117.0.0 217.117.15.255

Using the following code to check each range is there a more efficient method or way of doing this?

$range_start = ip2long("41.75.192.0");
$range_end   = ip2long("41.75.207.255");
$ip          = ip2long($_SERVER['REMOTE_ADDR']);
if ($ip >= $range_start && $ip <= $range_end) {
   // blocked
}

If you have access to .htaccess, you can block them on a configuration level and you don't need to worry about them in scripts.

order allow,deny
deny from 41.75.192.0
deny from 41.75.207.255

...

deny from 217.117.15.255
allow from all

Letting Apache keep them out altogether will save you a fair bit of trouble.
