Scructure:

index.php
<?php
$file = 'index.csv';
$array = file_get_contents($file);
echo $ctime = filectime($file) . PHP_EOL;
echo $atime = fileatime($file) . PHP_EOL;
echo $mtime = filemtime($file);
returns
1561541778
1561541779
1561541778
if file doesn't change, return param don't change
if file open, return param don't change
if file edit, return param change
but I want to get time of last call file_get_contents() to this file.
