Test PHP script to block IP address

According to Blog Technics: Script To Block IP Addresses on Blogspot, all one need to do is to upload a PHP script to a file host which allows PHP files, then add another script to just before </head> in the template (or add them to a HTML/Javascript gadget).

This was exactly what was done to Medical Information as a test to ban myself (IP Address 110.159.247.42) from that blog.

Let's go through what was done for the test. The following script:

<?php
/*
Blogspot IP address blocker. Provided by www.blogtechnics.info
*/
$iplist = array("IP Address 1","IP Address 2","IP Address 3"); // the list of banned IPs

$ip = getenv("REMOTE_ADDR"); // get the visitors IP address
// echo "$ip";
$found = false;
foreach ($iplist as $value) { // scan the list
if (strpos($ip, $value) === 0){
$found = true;
}
}

if ($found == true) {
echo "top.location = \"error.html\";\n"; // page to divert to
}

?>

was replaced with

<?php
/*
Blogspot IP address blocker. Provided by www.blogtechnics.info
*/
$iplist = array("110.159.247.42"); // the list of banned IPs

$ip = getenv("REMOTE_ADDR"); // get the visitors IP address
// echo "$ip";
$found = false;
foreach ($iplist as $value) { // scan the list
if (strpos($ip, $value) === 0){
$found = true;
}
}

if ($found == true) {
echo "top.location = \"error.html\";\n"; // page to divert to
}

?>

The above in a Notepad file (ASCII) was saved with a .php extension and uploaded to www.110mb.com/. The URL of the uploaded file is

http://bloggerfordummies.110mb.com/BlogspotIPblocker.php

Accordingly I am supposed to substitute BlogspotIPblocker.php in the code below:

<SCRIPT LANGUAGE='javascript' SRC='BlogspotIPblocker.php' TYPE='text/javascript'>
</SCRIPT>

with that URL whereupon the above become:

<SCRIPT LANGUAGE='javascript' SRC='http://bloggerfordummies.110mb.com/BlogspotIPblocker.php' TYPE='text/javascript'>
</SCRIPT>

and was copy-pasted to just before </head> in the template. The portion in the template just before </head> in the template thus become

<SCRIPT LANGUAGE='javascript' SRC='http://bloggerfordummies.110mb.com/BlogspotIPblocker.php' TYPE='text/javascript'>
</SCRIPT>
</head>
