You have used the same name for both the files. Hence it by default replaces the file to the name when goes to next page.

Difference between require() and require_once():  require() includes and evaluates a specific file, while require_once() does that only if it has not been included before (on the same page).
So, require_once() is recommended to use when you want to include a file where you have a lot of functions for example. This way you make sure you don't include the file more times and you will not get the "function re-declared" error.

Difference between require() and include() is that require() produces a FATAL ERROR if the file you want to include is not found, while include() only produces a WARNING.

There is also include_once() which is the same as include(), but the difference between them is the same as the difference between require() and require_once().

Require_once():-using this function we can access the data of another page once i. e we can not access the same page multiple times.

require():-using this function we can access the data of another page at the desire page multiple times i.e we can access the contents of same page multiple times.

Include() and require() dose same work.The difference is on error cheeking .Require () gives a fatal error when file cant load whereas include() gives a warning and continue to execute.

get_browser() attempts to determine the capabilities of the user's browser. This is done by looking up the browser's information in the browscap.ini file.

echo $_SERVER['HTTP_USER_AGENT'] . "<hr />\n";

$browser = get_browser();

foreach ($browser as $name => $value) {
    echo "<b>$name</b> $value <br />\n";
}

$_SERVER[HTTP_USER_AGENT]; by this method we can know the properties of browser.
