It is important to note that the cloaking is a practice frowned upon by the major search engines. His use of abusive / fraudulent can result in the removal of your site from search engines and recorded on a black list .i will advise you not to implement it on your site taking into account the risks involved (the best way to improve your site's visibility on search engines is to produce relevant content and popular).

The detection of the origin of the request is based on the IP address or User-Agent header in http package (note that the technique which uses the IP address is more reliable, but not infallible).

In PHP it is possible to retrieve information from the User Agent via the environment variable $ _SERVER [ "HTTP_USER_AGENT"]. The IP address for its part is available through the variable $ _SERVER [ "REMOTE_ADDR"].

Example : cloaking based on the USER-AGENT

In the following example, the function strpos () checks the strings to Googlebot. If the request comes from Googlebot a page is generated on the fly, otherwise there is generation of a standard page designed for human users.

<? php
$ found = strpos ($ _SERVER [ "HTTP_USER_AGENT"], "Googlebot");
if ($ found! == false) (/ / visitor is Googlebot, submit page cloak
>
<html>
... Page cloak for Googlebot. </ html>
<? php
)
else (/ / visitor is not googlebot, redirect to a standard page>
<html>
... Standard page ...
</ html>
<? php
)
>

Example : Cloaking on the basis of IP address

In this three-page code will be presented to different visitors (one for Googlebot, one for the robot Inktomi and a third for other users).

<? php
$ adresseip = strval ($ _SERVER [ "REMOTE_ADDR"]);
$ google1 = strpos ($ adresseip, "216.239.46");
$ google2 = strpos ($ adresseip, "64.68.8");
$ google3 = strpos ($ adresseip, "66249.");
$ slurp = strpos ($ adresseip, "66196");
if (($ google1! == false) | | ($ google2! == false) | | ($ google3! == false) | | ($ slurp! == false)) (
/ / Visitor is Googlebot and Inktomi, submit page cloakée
>
<html>
... HTML page cloakée for Googlebot and Inktomi

</ html>
<? php
)
else (/ / visitor is not Googlebot and Inktomi, to present the "standard"
>
<html>
... HTML page standard ...
</ html>
<? php
)
>
