Unfortunately I cannot get > it to work on my machine. [snip] So I figured it out... I was using the wrong command to compile libtidy. (I am not a *nix geek so I had no idea I was messing it up.) To get it working, I followed the instructions I found here: http://www.php.net/manual/en/ref.tidy.php#64281 My setup is slightly different from the person who wrote the directions in that I am running OS X 10.6.2 and PHP 5.2.12. However, the only difference between the instructions I followed and what I actually had to do is that the line to comment out for me was line 525 instead of 508. (The actual line is: typedef unsigned long ulong;) Thank you everyone for your help! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thank you, this looks like exactly what I need. Unfortunately I cannot get it
to work on my machine. I recompiled PHP with --with-tidy=/usr/local and this
is the version and modules in use:

When I run this test code
=
blahhello";
$config = array('indent' => true,
'wrap' => '0');
// Tidy
$tidy = new tidy();
var_dump($tidy);
$tidy->parseString($html, $config, 'utf8');
var_dump($tidy);
$tidy->cleanRepair();
var_dump($tidy);
echo tidy_get_output($tidy);
var_dump($tidy);
?>
=
I get this output:
=
object(tidy)#1 (2) {
["errorBuffer"]=>
NULL
["value"]=>
NULL
}
object(tidy)#1 (2) {
["errorBuffer"]=>
NULL
["value"]=>
NULL
}
object(tidy)#1 (2) {
["errorBuffer"]=>
NULL
["value"]=>
NULL
}
object(tidy)#1 (2) {
["errorBuffer"]=>
NULL
["value"]=>
NULL
}
I have no clue what I'm doing wrong...

what does it matter that it runs slowly, run it once and be done with it?
alternatively use the php tidy extension and avoid the file system and shelling
out altogether.
actually I'd imagine shelling out from a webserver process is the bottle neck
and not saving/reading
from the file system.
lastly I don't suppose you've heard of /dev/shm ?
and, er, no, I don't have experience with php://memory but you might try
searching for
other people's code:
