index.php
<?php
function print_title(){
if(isset($_GET['id'])){
echo $_GET['id'];
} else {
echo "Welcome";
}
}
function print_description(){
if(isset($_GET['id'])){
echo file_get_contents("data/".$_GET['id']);
} else {
echo "Hello, PHP";
}
}
function print_list(){
$list = scandir('./data');
$i = 0;
while($i < count($list)){
if($list[$i] != '.') {
if($list[$i] != '..') {
echo "<li><a href=\"index.php?id=$list[$i]\">$list[$i]</a></li>\n";
}
}
$i = $i + 1;
}
}
