ip - How show IPv4 only with REMOTE_ADDR in PHP? -

-

i have question variable : $_server['remote_addr']. wish recovers ip addresses in ipv4 format . extracted me few times in ipv6 format .

how do?

$_server['remote_addr'] contains address of visitor. if contains ipv6 address visitor used ipv6 , there no ipv4 address. , vice versa of course. these days have able deal both.

some visitors have ipv4, have ipv6 , have both. browser decides available , use, , that's you'll see. note browser has both might switch between ipv4 , ipv6 between requests if deems necessary connectivity.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
