well its for a tutorial section. each tutorial is a txt file in a far far away folder.
first someone will will choose a language, and then they select a page/tutorial.

i have this so far

code:
<?php
$page = htmlentities($_GET['page']) ;
$language = htmlentities($_GET['lan']) ;
if (!isset($_GET['page'])) {
if(!isset($_GET['lan'])) {
include ("pages/code/home.txt");
}
else {
include ("pages/code/$language.txt");
}
}
else {
include("pages/code/$language/$page.txt");
}
?>

now i want to create a sorta error page, if the file cannot be found, then it echos "page cannot be found"

thanks for the help :)

you just use file_exists

http://au.php.net/manual/en/function.file-exists.php

so you could use

code:
$file = "path to file here";
if (!file_exists($file)) {
die("page can not be found");
}
just put it before anything echo's in your code and when the file can not be found it will echo "page can not be found" then kill the script

so in your script it would be something like

code:

<?php
$page = htmlentities($_GET['page']) ;
$language = htmlentities($_GET['lan']) ;
if (!isset($_GET['page'])) {
if(!isset($_GET['lan'])) {
include ("pages/code/home.txt");
}
else {
$file = "pages/code/$language.txt";
if (!file_exists($file)) { die("page can not be found");}

include ("$file");

}
}
else {
$file = "pages/code/$language/$page.txt";
if (!file_exists($file)) { die("page can not be found");}

include ("$file");
}
?>
[/code]
