Dear Readers..:)
The following php coding will display the environment in which you work, that is the browser and operating system you use.
Functions Used
1. getenv - >GET ENVIRONMENT - which will get the environment of the user (HTTP_USER_AGENT)
2. preg_match -> It is used to match the values of the browser and OS of user with the values in the code
Code
<html>
<head>
<title>Environment Identification</title>
</head>
<body>
<?php
$environment=getenv("HTTP_USER_AGENT");
if(preg_match("/Windows/i","$environment"))
{
$OS="Windows";
}
if(preg_match("/Mozilla/i","$environment"))
{
$browser="Mozilla";
}
print("The Operating System is $OS <br>");
print("The browser is $browser")
?>
</body>
</html>
Usage :
It is used in Ethical-Hacking and in general in the domain of Network Security
Note :
In the above coding i have simply used only one browser and one operating system. You can expand this coding.
