get the size of the output of a php file?

[colfaxrev]

Is there a way of getting the final size in bytes of the output of a php file?

i have a separate php file that is doing the following...

[code]
print "filesize[" . filesize('roro3.flv') . "]";
[/code]

which outputs...
filesize[18492343]

so that works fine...

I want to get the FINAL size in bytes for the output of a php file... i tried this (which i was sure wouldn't work)

[code]
print "filesize[" . filesize('tracking.php?action=show') . "]";
[/code]

You can see that file for youself here...
http://triotalentagency.com/newsite/tracking.php?action=show

but that code prints out this...

filesize[]

i also tried to use readfile() but that didn't seem to work....
is there anyway to do this?

thanks!

if you are trying to find the size of the output of a page that will always be a constant size you can probably do this:

[code]
$site = file_get_contents('http://www.mywebsite.com/tracking.php?action=show');
print "filesize[" . strlen($site) . "]";
[/code]

I believe that "filesize" only works for local files, so "filesize('http://www.mywebsite.com/tracking.php?action=show')" wouldn't work. Since 'http://www.mywebsite.com/tracking.php?action=show' is clearly not local.

Also, if what you were attempting to do was to retrieve the file locally, the script would be looking for a file named 'tracking.php?action=show', not a file named 'tracking.php'.

(Also retreiving a php file locally gets the code of the file, not the output. ie: filesize("helloworld.php") would get the length of "<?php echo 'Hello World'; ?>" rather than the length of "Hello World")

::test1.php::
[code]<?php

for($i=0; $i<250; $i++) echo 'x';

?>[/code]

::test2.php::
[code]<?php
 
  ob_start();
  include('test1.php');
  echo strlen(ob_get_clean());  // --> 250
 
?>[/code]
