PHP动态页面包括

Question

I have an simple PHP script that includes a file, when it's requested via URL.

for an example: http://example.com/index.php?page=about So this includes the page about.inc

This is working, but i have another problem. When someone visits the homepage so just: http://example.com/ . It will show me this

Undefined index: beta in /home/admin/domains/mydomainname.nl/public_html/index.php on line 3

That is:

$page = $_GET['page'];

I know I can disable the error notice in PHP, but this is not a solution but a workaround.

$path = 'app/inc/pages/dynamic/';
$page = $_GET['page'];
$php  = '.inc';
$both = $path . $page . $php;
$pages = array('index', 'home', 'about', 'contact');
if (!empty($page)) {

    if(in_array($page,$pages)) {
        //$page .= '.php';
        include($both);
    }
    else {
    include('app/inc/pages/dynamic/404.inc');
    }
}
else {
    include('app/inc/pages/dynamic/home.inc');
}
}

It does include the homepage via

else {
    include('app/inc/pages/dynamic/home.inc');
}

My question is how to solve this?

Try this: replace 3 no line by this:

  $page = isset($_REQUEST['page']) ? $_REQUEST['page'] : '';

It will set empty in the $page variable if no page is provided. You have double $ in $path. Full code:

$path = 'app/inc/pages/dynamic/';
$page = isset($_REQUEST['page']) ? $_REQUEST['page'] : '' ;
$php  = '.inc';
$both = $path . $page . $php;
$pages = array('index', 'home', 'about', 'contact');
if (!empty($page)) {

    if(in_array($page,$pages)) {
        //$page .= '.php';
        include($both);
    }
    else {
        include('app/inc/pages/dynamic/404.inc');
    }
}
else {
    include('app/inc/pages/dynamic/home.inc');
}
