如何在php脚本文件中加载/包含/调用/使用/引用html静态网页文件

有好几种方法和函数供大家使用:

include()
include_once()
require()
require_once()
file_get_contents()

例如/例子:
// Create a DOM object from a string
$html = str_get_html('<html><body>Hello!</body></html>');

// Create a DOM object from a URL
$html = file_get_html('http://www.google.com/');

// Create a DOM object from a HTML file
$html = file_get_html('test.htm');
<?php
if(some condition)
{
    //Dont allow access
}
else
{
    include ("your_file.html");
}
?>

OR

<?php
if(some condition)
{
    //Dont allow access
}
else
{
    readfile("your_file.html");
}
?>

readfile is faster and less memory intensive than file_get_contents

if(some condition)
{
    //Dont allow access
}
else
{
    echo file_get_contents("your_file.html");
}

OR

if(some condition)
{
    //Dont allow access
}
else
{
    require_once("your_file.html");
}
