[PHP] Gzipped output
Hello,
is it possible to make something like "gzipped echo"?.
My idea was:
$gzOut = gzopen('php://output','w');
but it fails with an error: Warning: gzopen(php://output) [href='function.gzopen'>function.gzopen]: could not make seekable -
php://output
That script generates a large text file to download, so I thought I can
gzip it somehow to make the downloads faster. The buffered way (to load
all the output to some $buffer and then echo gzencode($buffer,6);)
consumes too much memory.
Can anyone help me with this?
Best regards
Jakub Cermak

Re: [PHP] Gzipped output
Yes, I thought about this, but this has a big disadvantage - the client
must wait for the file to be fully processed and compressed and then he
can start downloading. I'd like to let the client start downloading the
compressed parts while the further parts are still being processed and
compressed - it's similar to streaming concept. I hope you can see what
I mean.

You could write it to a local file, then do:
header("Content-Type: application/x-gzip");
Header("Content-Disposition: attached; filename=\"\"")
passthru("gzip -c ");

Re: [PHP] Gzipped output
That would do the trick if it was allowed at the server but it isn't :( And it's not my server and I can't change its settings.

Maybe apaches mod_deflate is what you're after? That will do in-flight compression. /Per Jessen, Zürich
[PHP] PHP 4.2.2 & vpopmail
I have little problem with vpopmail functions from PHP 4.2.2. When I use
vpopmail_auth_user ( "blah", "foo.bar.pl", "secret string" ); I get no
correct return value ( echo vpopmail_auth_user ( "blah", "foo.bar.pl",
"secret string" ); - give me no result ). This values are 100% good. I
have Apache with suEXEC (VirtualHost -> User vpopmail, Group vchkpw).
Here's details:
My Apache:
./configure \
--enable-suexec \
--suexec-caller=www-data \
--suexec-docroot=/usr/local/apache \
--server-uid=www-data \
--server-gid=www-data \
--enable-module=log_referer \
--enable-module=usertrack \
--disable-module=imap \
--activate-module=src/modules/php4/libphp4.a \
--prefix=/usr/local/apache
cd src
# ADD line "AddModule modules/php4/libphp4.a" in Configure
./Configure
make
cd ..
make install
My PHP:
./configure \
--enable-tokenizer \
--enable-track-vars \
--enable-ftp \
--enable-safe-mode \
--with-vpopmail="/home/vpopmail" \
--with-apache=${SRC_APACHE_DIR} \
--prefix=/usr/local
make;make install
infophp(); produce:
vpopmail version 5.2.1
vpopmail uid/gid php uid/gid/euid/egid 89/89 33/33/33/33
vpopmail dir /home/vpopmail
vpopmail vadddomain /home/vpopmail/bin/vadddomain
vpopmail vdeldomain /home/vpopmail/bin/vdeldomain
vpopmail vaddaliasdomain /home/vpopmail/bin/vaddaliasdomain
vpopmail valias support Enabled
UIDs and GIDs :
# cat /etc/group | grep 'vchkpw'
vchkpw:x:89:
# cat /etc/passwd | grep 'vpopmail'
vpopmail:x:89:89::/home/vpopmail:/bin/bash
# cat /etc/passwd | grep 'www-data'
www-data:x:33:33:www-data:/var/www:/non
Is this problem of my configuration or broken code of php extensions ?

I solve that problem. Apache was not runed as vpopmail.vchkpw. Suexec is
useless until you turn php as cgi. The better way (than suexec) is run
separate apache server as vpopmail.vchkpw user on other port. Now
vpopmail functions are ok.
