*is there a way to convert the bytes to kb, mb or gb? Is there a way to add commas?
i have
$fs = filesize($file);
echo $fs;
what else would i add to make it output something like this
6,332 bytes or
6.3 kb or others?
function fileSizeInfo($fs)
{
$bytes = array('KB', 'KB', 'MB', 'GB', 'TB');
// values are always displayed in at least 1 kilobyte:
if ($fs <= 999) {
$fs = 1;
}
for ($i = 0; $fs > 999; $i++) {
$fs /= 1024;
}
return array(ceil($fs), $bytes[$i]);
}
<?php
$dir = opendir(".");
while (($file = readdir($dir))!== false)
if ($file!= "." && $file!= "..")
{
$fs = filesize($file);
function fileSizeInfo($fs) { $bytes = array('KB', 'KB', 'MB', 'GB', 'TB');
// values are always displayed in at least 1 kilobyte:
if ($fs <= 999) { $fs = 1; }
for ($i = 0; $fs > 999; $i++) { $fs /= 1024; }
return array(ceil($fs), $bytes[$i]); }
echo "$file $fs";
}
closedir($dir);
?>

when i run the script it just says
Array
<?php
function fileSizeInfo($fs) { $bytes = array('KB', 'KB', 'MB', 'GB', 'TB');
// values are always displayed in at least 1 kilobyte:
if ($fs <= 999) { $fs = 1; }
for ($i = 0; $fs > 999; $i++) { $fs /= 1024; }
return array(ceil($fs), $bytes[$i]); }$dir = opendir(".");
while (($file = readdir($dir))!== false)
if ($file!= "." && $file!= "..")
{
$fs = filesize($file);echo $file.' '.fileSizeInfo($fs);
}closedir($dir);
?>
dc
file001.mp3 array
file002.mp3 array
file003.mp3 array
print_r(fileSizeInfo($fs));
dc
<?php
function size_hum_read($size){
$i=0;
$iec = array("b", "kb", "mb", "gb", "tb", "pb", "eb", "zb", "yb");
while (($size/1024)>1) {
$size=$size/1024;
$i++;
}
return substr($size,0,strpos($size,'.')+4).$iec[$i];
}
$dir = opendir(".");
while (($file = readdir($dir))!== false)
if ($file!= "." && $file!= "..")
{
$fs = filesize($file);
//you can format this however you want
echo $file;
echo "<br>";
echo size_hum_read(filesize($file));
echo "<br>";
echo "<br>";
}
closedir($dir);
?>
Save this 1st file as index.php

next save this file as force-download.php

finally put both of these files index.php and force-download.php in the server folder you want to populate a list for.
i found this script system usefull for sharing files to clients, for example a hip hop beat producer can put all his draft beats here and the remote emcee's can easily access them for writing their lyrics.
If you still need help with functions, you should read up about them at php.net: Functions [us2.php.net].
Best of luck!
