I have a download section in my index.php that I'd like to add a download counter to but have no idea how to accomplish this. The existing code works perfectly but I'd like to know how many times the file is downloaded. Would prefer not to use a database.

CODE

<!--  DOWNLOAD -->
<div id="download" class="stylized">
    <div "myform">
    <div class="container">
        <div class="row">
            <div class="download">
                <br /><br>
                <h1><center>FoxClone Download Page</center></h1>
                   <?php
                    $files = glob('download/*.iso');
                    $file = $files[count($files) -1];
                    $info = pathinfo($file);
                    $filename =  basename($file);
                    $filename = ltrim($filename,'/');
                    $md5file = md5_file($file);
                   ?>

                     <div class="container">
                        <div class="divL">                      
                            <h3>Get the "<?php echo "{$filename}";?>" file (approx. 600MB)</h3>
                        <center>  <a href="<?php echo "/{$file}";?>"><img src="images/button_get-the-app.png" alt=""></a> </center><br />
                            <h3 style="margin-bottom: 0.5rem;">The MD5sum for "<?php echo "{$filename}";?>" is "<?php echo "{$md5file}";?>  


Thanks in advance,
Larry
