Friendly file size for a file using php code

Hi friends, In this post i would like to explain about get the friendly file size using simple php code.

PHP Code

following code is very simple to get the friendly file size format using php code.

function frndlyfilesize($filesize){

if(is_numeric($filesize)){
$decr = 1024;
$step = 0;
$prefix = array('Byte','KB','MB','GB','TB','PB');

while(($fileName / $decr) > 0.9){
$filesize = $filesize / $decr;
$step++;
}
return round($filesize,2).' '.$prefix[$step];
} else {

return 'Nothing';
}
}

 

To call that function :

$ filesize = filesize("test.jpg");
$newSize = frndlyfilesize($filesize);

 

Expected output like the format :

 

5 MBĀ  or 5 KB or 5 GB ……

    I think it should be
    while(($filesize / $decr) > 0.9)

    and NOT
    while(($fileName / $decr) > 0.9)
