  echo $counterVal;

This is click counter... Counter.txt only number...

How to add a date?

Counter / Date

1. 2021-02-28 19:50:47

2. 2021-02-23 17:57:11

etc

Append the current datetime each time instead of the count. The number of records will give you the count.

$counter_name = 'counter.txt';
file_put_contents($counter_name, date('Y-m-d H:i:s')."\n", FILE_APPEND);

$k = 0;
foreach (file($counter_name, FILE_IGNORE_NEW_LINES)  as $dt) {
    ++$k;
    echo "$k : $dt<br>";
}

If you're going to be prepending data to the file then you're also going to need to deal with file locks. In case two different PHP requests try to update the counter.

Obligatory "but you really shouldn't be using a file for this" comment here.

Thanks

Code:
 

<?php
  $counter_name = 'counter.txt';
file_put_contents($counter_name, date('Y-m-d H:i:s')."\n", FILE_APPEND);

$k = 0;
foreach (file($counter_name, FILE_IGNORE_NEW_LINES)  as $dt) {
    ++$k;
    echo "$k : $dt<br>";
}  

  if (!file_exists($counter_name)) {
    $f = fopen($counter_name, "w");
    fwrite($f,"0");
    fclose($f);
  }

  $f = fopen($counter_name,"r");
  $counterVal = fread($f, filesize($counter_name));
  fclose($f);

  $counterVal++;

  $f = fopen($counter_name, "w");
  fwrite($f, $counterVal);
  fclose($f);

  echo $counterVal;
?>

Date work but counter no:

2021-03-02 14:56:08
2021-03-02 14:57:41
2021-03-02 14:57:42
2021-03-02 14:57:42
2021-03-02 14:57:45

Counter must have first 1) < counter

Time not correctly...

5) 2021-03-02 14:56:08 - new must be above like 14:57:45
4)2021-03-02 14:57:41
3) 2021-03-02 14:57:42
2) 2021-03-02 14:57:42
1) 2021-03-02 14:57:45

correctly is

5) 2021-03-02 14:57:45

4) 2021-03-02 14:57:42

3) 2021-03-02 14:57:42

2)2021-03-02 14:57:41

1) 2021-03-02 14:56:08

Very thanks

If you want latest first, reverse the array

$counter_name = 'counter.txt';
file_put_contents($counter_name, date('Y-m-d H:i:s')."\n", FILE_APPEND);     // creates file if it doesn't exist
                                                                             // appends if it does exist

$k = 0;
$clicks = file($counter_name, FILE_IGNORE_NEW_LINES|FILE_SKIP_EMPTY_LINES);
$clicks = array_reverse($clicks);
foreach ($clicks as $dt) {
    ++$k;
    echo "$k : $dt<br>";
}

giving

1 : 2021-03-02 13:27:25
2 : 2021-03-02 13:26:23
3 : 2021-03-02 13:24:19
4 : 2021-03-01 18:28:04
5 : 2021-03-01 18:25:28
6 : 2021-03-01 18:25:23
7 : 2021-03-01 18:25:17
