File size function

File size function


<?php 
function file_size($file) 
{ 
//store the actual size of the file 
$size = filesize($file); 
if($size >= 1073741824) 
{ 
$size = round($size / 1073741824) . " gigabytes "; 
} 
elseif($size >= 1048756) 
{ 
$size = round($size / 1048576) . " megabytes "; 
} 
elseif($size >= 1024) 
{ 
$size = round($size / 1024) . " kilobytes "; 
} 
else 
{ 
$size = $size . " bytes "; 
} 
return $size; 
} 
?> 

Now lets test this function out with the following . 

<?php 
echo "index page is " . file_size("index.htm"); 
echo "<br>"; 
echo "this page is " . file_size("filesize.php"); 
?>
