I would like to know how I can block my site that is under maintenance and leave free access for two ips, I'm doing this, but it only leaves one free. I want you to be free for both of you.
$ip = '10.11.30.175';
$ip ='10.11.30.182';
if ( $_SERVER['REMOTE_ADDR'] != $ip )
die('Site em manutenção, voltaremos em instantes');
You can use the in_array() function to check which ips has access to the site.
$validos = array('10.11.30.175', '10.11.30.182');
if (! in_array($_SERVER['REMOTE_ADDR'], $validos)) die('Site em manutenção, voltaremos em instantes');
Following your reasoning:
$ip1 = '10.11.30.175';
$ip2 ='10.11.30.182';
if ( $_SERVER['REMOTE_ADDR'] != $ip1 || $_SERVER['REMOTE_ADDR'] != $ip2 )
die('Site em manutenção, voltaremos em instantes');
An option to block accesses would be via .htaccess :
APACHE 2.4
<Limit GET POST>
Require all denied
Require ip 10.11.30.175
Require ip 10.11.30.182
</Limit>
APACHE 2.2
<Limit GET POST>
order deny,allow
deny from all
allow from 10.11.30.175
allow from 10.11.30.182
</Limit>
Your script should be like this
first part (validation function)
function valida($ip){
$retorna=false;
$liberado=array('10.11.30.175','10.11.30.182');
for($i=0;$i<count($liberado);$i++){
if($ip==$liberado[$i]){ $retorna=true; }
}
return $retorna;
}
This top cod can be an external include or anywhere on your php page to use just do the following
if (!valida($_SERVER['REMOTE_ADDR'])) die('Site em manutenção, voltaremos em instantes');
If you want to add more ips just include in the array of the variable released plus ips separated by, within single quotation marks.
