Hi, included files with php include_once inherit the compression stablished by
in the main file where the included files are being included?
Or the included files do not get compresed?
Thanks to anyone who knows about this.

It's not the files themselves which are being compressed, just the output. So as long as ob_start("ob_gzhandler"); is set, anything that outputs after it will be compressed.

Including anything inside all of the files included with include_once ?
I do not have to add
to files that are meant to be included on main files that already have
?

Exactly, in fact if you do call it again you'll get an error I believe.

I think PHP will just start another compressed output buffer. No errors.
But it means some stuff will be compressed twice, which is not good.

Not to sound like a jerk but your wrong.
Code: Select all
<?php
ob_start("ob_gzhandler");
ob_start("ob_gzhandler");
echo 'hello world';
ob_end_flush();
?>
will produce...
Warning: ob_start() [ref.outcontrol]: output handler 'ob_gzhandler' cannot be used twice in /var/www/test.php on line 3
hello world
