PHP Code:

$ip = getenv("REMOTE_ADDR"); 


I'm looking to exclude a range of IP addresses from being added to my database in one of my scripts (mainly because they are search engine spiders).

Now I can exclude IP address easily with if else statements. And I have excluded my IP address, and google's spider. In this example 111.111.111.111 is my IP and 222.222.222.222 is google's spider.

PHP Code:

if ($ip != '111.111.111.111' || $ip != '222.222.222.222') {

// stuff to add to MySQL database

} 


I want to exclude more IP addresses from other spiders, and I would normally just add

PHP Code:

|| $ip != 'oth.ip.add.ress' 


but what if I wanted to exclude a range of IP addresses, like Live Search which have about 10 IPs starting with 65.55.208

Isn't there some kind of way to exclude any number that follows 65.55.208.

Surely this is easy, its just not clear in any PHP tutorials.

Hi Gilligan,

Yup... loads of ways - heres just one (and im not saying its the best way, but its a way)

PHP Code:

if(!ereg("^65.55.208", $ip)){ 
//not a spider so register code here ...
} 


all the best

//edit: thought it would help if I told you what that does, for learning purposes... it just scans the variable $ip to see if it beginds 65.55.208.. if it does, nothing happens ( you could use an else to make something happen if you like) if it doesnt, runs the code inside the curelys

Thanks for the reply, just want to ask one more question.

to fit:

PHP Code:

if(!ereg("^65.55.208", $ip)){  
//not a spider so register code here ... 
} 


into my previous statement

PHP Code:

if ($ip != '111.111.111.111' || $ip != '222.222.222.222') {

// stuff to add to MySQL database

} 


Would it simply become:

PHP Code:

if ($ip != '111.111.111.111' || $ip != '222.222.222.222' || !ereg("^65.55.208", $ip)) {

// stuff to add to MySQL database

} 


And also, wouldn't it be

65.55.208.^

seeming as the list of similar IPs all have the same start?

yep you have included it into your current code correctly, good job/

Not sure what you mean on your final question.. you must put the ^ sign at the front as it checks for the string that follows the ^ at the start of the $ip variable...

basically, ^65.55.208 means is 65.55.208 at the start of the IP. You can remove the ^ sign all together and it will just check if 65.55.208 exists anywhere in the string

Oh right, I thought ^65.55.208 meant that it checks everything before the IP, never mind then

nope, its the other way round

PHP Code:

if (!preg_match('!111.111.111.111|222.222.222.222|^65.55.208!', $_SERVER['REMOTE_ADDR'])) {
   add_me();
} 


Just realised, using || is stupid to use in this case.

Basically, I wanted it to add stats if it isn't my ip or a search engine ip.

But || makes it so that if it is my ip, but isn't a search engine's ip (will always be true no matter what) then it will add my ip's stats anyway. Stupid eh?

Anyway I changed it to &&, makes more sense that way.
