here is some sample code to retrieve the size of an image and then save the image to disk, from a web server.

$imgDir = "/home/httpd/upload/new.gif"; // save new gif here
$imgPath = '/foo/bar.gif'; // remote location
$imgHost = "www.foo.com";
$fp = fsockopen($imgHost, 80, &$errno, &$errstr, 30);
if(!$fp) {
echo "ERROR: $errno: $errstr";
} else {
fputs($fp,"HEAD $imgPath HTTP/1.0\nHost: $imgHost\n\n");
while(!feof($fp)) {
$response .= fgets($fp,128);
}
fclose($fp);
}
$imgSz = ereg_replace("(.*)(Content-Length: )([0-9]*)(.*)","\\3",$response);
$file = fopen($imgPath,"br"); // open external gif in binary mode and RO
$contents = fread( $file, $imgSz );
fclose($file);
$file2 = fopen($imgDir,"wb"); // open new local file in bin/write mode
fwrite($file2,$contents,$imgSz);
fclose($file2);

here's a nifty thing to have the filesize rounded to 2 decimals, AND display size in bytes/kilo/meg/gig depending on filesize..
(dunno if this could be cut down, but it's at least a start)
--- cut ---
<pre>
$file_size = filesize(<FILENAME>);
if ($file_size >= 1073741824) {
$file_size = round($file_size / 1073741824 * 100) / 100 . "g";
} elseif ($file_size >= 1048576) {
$file_size = round($file_size / 1048576 * 100) / 100 . "m";
} elseif ($file_size >= 1024) {
$file_size = round($file_size / 1024 * 100) / 100 . "k";
} else {
$file_size = $file_size . "b";
}
</pre>
--- end cut ---

have fun with this..

jesse.

the max_file_size problem you're having can be resolved by making sure that a) your max_file_size var in your form upload is set correctly and b) PHP is configured for upload_max_filesize to be at least that large. The default PHP config is 2MB. By adding or changing a line in the php3.ini, or your apache.conf directives you should be able to fix your problem.

hi, can you email replies please. :)
Can filesize(); check the files size of a file ON A REMOTE SERVER?

Cheers

As far as I can see, you cannot view the filesize of objects on remote servers. If anyone knows any differently, please post, I'd love to know how.

Why does <PRE>$thesize = filesize($url);</PRE> not work on http:// urls? - And wouldn't it be a cool feature to have in PHP4???

About finding the file size of a remote file, I highly doubt that you could access this kind of information on a remote machine. This would be a huge security issue. If you really want to find the size of a file on a remote web server, you could write a socket script to connect to the desired HTTP server and by sending:



HEAD /filefolder/file.jpg HTTP/1.1&lt;CRLF&gt;

Host: www.yourhostname.com&lt;CRLF&gt;&lt;CRLF&gt;



Then the webserver should send you the header of that file which contains the header field "Content-Length: ". It's value is the size of the file requested. Note that you need the "Host: " header field if you specify HTTP version 1.1 (HTTP/1.1) or the server will respond with an error. Also, the command HEAD is not supported by all servers. You can use GET instead, but the server will send the header with the file content which will take longer to process.



Check the HTTP RFC for more info on the protocol. If the file is not on a web server, then your on your own. ;)

Is there a way, through PHP to add up the size of all the files without:
1. using echo `du -sk` and
2. looping through an array of files and calling the filesize() function over and over.

About the filesize checking on a remote server:



I don't know how to do it and if it's possible (I doubt it)... But how does my browser it when downloading a file? When I download a file it always says something like "1,58Mb of 2,79Mb completed"? Anyone?

I think it is a heading, sometimes it does not write the size, maybe because the server does not send the size.

Method of checking if a file is empty.



$file="$LLQE_$date.txt";


$header = fopen("$file","a+");


if (filesize($file)==0) {


echo "The file is empty";

}
I had some trouble with it at first.

I try to display the download file in KB but its display like 24,450 MB.

This might help for filesize on a remote server.. from faqts.com

<pre>
Loop using fread and check for eof with a predefined buffersize (example using 1000 bytes buffer)

$fp = fopen ($picture_name, "r");
while (!feof($fp))
{
$contents .= fread($fp, 1000);
}
fclose($fp);

print "filseize: " . strlen($contents) . "
";

$fp2 = fopen ("c:/temp/test.gif","w");
fwrite($fp2,$contents,strlen($contents));
fclose($fp2);
</pre>
