chose include through variables

[lisa3711]

Hi- Very new to this. here is the question.

I have index.html.

On this page are four links:

linkone
linktwo
linkthree
linkfour

I want to code the href to pass a variable to a php page (pagetwo.php), then based on the variable in the href, use include to display a file.

My includes are txt files. af.txt, gl.txt, etc...

So, I am thinking linkone on index.html would be this:
/pagetwo.php?page=af
/pagetwo.php?page=gl

On pagetwo.php... I am looking for secure code to say
if the variable is 'af' include the file 'af.txt'

So, two questions:

1.)I've done some reading, and simply using an include seems like a security risk and
2.) What is good code for the second page.

Thanks in advance!

$page = $_GET["page"];
if ($page=="af") {
	$filename = "af.txt";
}
elseif ($page=="gl") {
	$filename = "gl.txt";
} else {
	//etc

}
$F = fopen($filename,"r");
while (!feof ($F)) {
    $buffer = fgets($F, 4096);
    echo nl2br($buffer);
}
fclose ($F);

The above will list a text file without include.
