<?php

function TotalBytes($definefilename)
{
$isfile = is_file($definefilename); //define the file name
if ($isfile == 1) //if the file is true
{
$handle = fopen($definefilename, "r"); //open the file check the information
$contents = fread($handle, filesize($definefilename)); //define the filesize
$expode = explode("\n", $contents); //explode the "\n char"
$count = count($expode, COUNT_RECURSIVE); //count how much total
while ($i <= $count) //count total values
{
$totalcount = $totalcount + $expode[$i] . "\n"; //count total values; :D
$i++;
}
return $totalcount; //return total aye it works
}
else
{
return "Not Found";
}
}
echo TotalBytes('data.txt');
?>
