The example in this article describes how to simply implement a text counter in PHP. Share it with everyone for your reference, the details are as follows:
<?php
if (file_exists('count_file.txt'))
{
$fil = fopen('count_file.txt', r);
$dat = fread($fil, filesize('count_file.txt'));
echo $dat+1;
fclose($fil);
$fil = fopen('count_file.txt', w);
fwrite($fil, $dat+1);
}
else
{
$fil = fopen('count_file.txt', w);
fwrite($fil, 1);
echo '1';
fclose($fil);
}
?>
