How do i find out the size of a external file using php

what i need is

when i enter the link of the external file the size is displayed please help

thanks

 

you could download it to your server first and then get the size, but not every hoster allows url file access.

 

like this, requires curl, if you put your mind to it you could probably do exactly the same thing with socket, but no one is paying me, just proof of concept

<?
$size = "";
$type = "";
function donkey_work($ch, $header)
{
   	global $size;
   	global $type;
   	if(ereg("Content-Length:", $header))
	{
		$temp = split(":", $header);
		$size = trim( $temp[1] );
	}
	if(ereg("Content-Type:", $header))
	{
		$temp = split(":", $header);
		$type = trim( $temp[1] );
	}
   	return strlen($header);
}

function krfsize($remote_file)
{
   global $data;
   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL, $remote_file);
   curl_setopt($ch, CURLOPT_HEADER, 1);
   curl_setopt($ch, CURLOPT_NOBODY, 1);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'donkey_work');
   curl_exec ($ch);
   curl_close ($ch);
   return $data;
}
function human_bytes( $type = "MB", $precision = "1" )
{
	global $size;
	switch($type)
	{
		case "GB": 
		return round(( $size / 1073741824 ), $precision); 
		break;
		
		case "MB":
		return round(( $size / 1048576 ), $precision);
		break;
	}
	
}
// Only include the file if it's saved seperately
// include("krfsize.php");
// Execute this to fill the data first
krfsize("http://www.jewlzk.com/test100.zip");
// Will echo the filesize is a human readable format, takes
// two parameters human_bytes( [string] MB or GB, [int] precision of rounding )
// both parameters are optional
echo human_bytes(  );
// echo human_bytes( "GB" ); # Gigabytes example, change precision for this one
// echo $size; # $size contains the filesize in bytes
// echo $type; # $type contains the filetype
?>

PHP:

I should aso mention that php5 ha a get_headers() function built in that will return the headers as an array, but not everyone has php5, or knows how to use an array, it's pretty simple code above and commented where it needs to be, prolly best to save as a file on it's own and include() it when you need it

Have fun .....
