用php创建向上计数的html文件？

Question

I would like to know if I could create a new php file everytime someone clicks a button. The button looks like this:

<button onClick="generate.php"> Generate </button>

PHP:

What do I do here?

I would like the page generated to be a number that goes up for every button click. So, 50 pages have been generated, so the next click makes a file named "51.html", and so on.

I know that for the log, you have to do something like this:

<?php
$file = fopen('countlog.txt', 'r');
$dat = fread($fil, filesize('./class/countlog.txt')); 
$write = fwrite($file, $data+1);
echo $data;
fclose($file);
?>

Try This

<?php 

define('START_FILENAME', __DIR__ . "/starting_point");

if (file_exists(START_FILENAME))
{
    # There is that File - read its content
    $start = (int) file_get_contents(START_FILENAME);
}
else
{
    # No File Found - Create new File
    $start =  0;
    @file_put_contents(START_FILENAME, "$start");
}

# When Form Submitted
if (isset($_POST) and isset($_POST['Click']) and $_POST['Click'] == "Generate")
{
    $file_name = "{$start}.html";
    @file_put_contents($file_name, "Hello World!");
    # Update Counter too
    $start = $start + 1;
    @file_put_contents(START_FILENAME, "$start", 0);
    echo "Generated Filename - $file_name";
}


?>
<form action="demo.php" method="post" accept-charset="utf-8">
    <input type="submit" name="Click" value="Generate">
</form>
