创建一堆php / html文件的简短方法？ [关闭]

I am trying to create a website.The website will have so many gifs/pics and so I have to create php/html file just for showing a gif/pic.So I just have to create so many php/html file or there is any short way.

For ex. I create gif.html and gif1.html , gif10000.html,takes so many times.Thought maybe there is a short way ?

Pass an element to display in GET parameter, for example:

show_picture.php?file=gif10000.gif

and in PHP retrieve it by $_GET['file'] (make sure you sanitize the input first).

Here is full PHP:

<?php
$allowedImages = array(
    'gif10000.gif',
    'gif2.gif' //etc
);

$file = $_GET['file'];
if (in_array($file, $allowedImages)) { 
    echo '<img src="'.$file.'" />';
}
?>
