execute PHP -> return output to string

[Christopher-Robin]

Hi

I've got a problem and I hope someone can help me:

I want a PHP script to call another PHP script, execute it and return its
OUTPUT (not its content) into a STRING in the first script.

Don't really understand can't you use function() ?

to clarify...


ob_start(); // start trapping output
include "foo.php"; // produce output
$output = ob_getcontents( ); // get contents of trapped output
ob_end_clean(); // discard trapped output and stop trapping

cool thing is you can nest these too :)
you can do other things using a call-back. pretty funky stuff really :)

See "output buffering", check the spelling of those functions. I'm too
lazy to look it up...

Exactly this is what I did so far before I realized, that the output buffer
is limited in size to 'output_bufferi ng' in the php configuration, which is
set to 4096 bytes by default, but 4K is just not enough for me. I need it do
be unlimited. This could be done with 'output_bufferi ng = On', which limits
the buffer to the RAM size for the script offered in 'memory_limit' (8M by
default).


PS: It must be done this way to make sure everything in the buffer before is
reinsert afterwards.

$old=ob_get_con tents(); ob_clean(); ob_start(); // you may leave ob_start();
include ...;
$out=ob_get_con tents(); ob_clean();
echo $old;
