To install this PECL extension on Ubuntu 12.10 run the following:
sudo apt-get install php-http make
sudo pecl install pecl_http
Then add the line "extension=http.so" to php.ini (Normally located at /etc/php5/apache2/php.ini) and restart Apache (sudo service apache2 restart).

For others who can't find pecl_http for PHP 5.3 on Windows...
You can download php_http.dll for PHP 5.3 from the official PHP for Windows site (windows.php.net) at http://downloads.php.net/pierre/

If you are on Arch linux you can install this via pear.
just install pear first with pacman, then once php-pear is installed you can # pecl install pecl_http

To install this extension on Gentoo Linux just run the package manager:
emerge -q pecl-http
and add the extension into php.ini
extension=http.so ( do not have the php_ prefix )

On Fedora, I had to do 'yum install curl-devel' to avoid missing curl.h error.

in Ubuntu 10.10 I had to create this file:
/etc/php5/conf.d/http.ini
and add this line:
extension=http.so

Just to add to the above.
I had to install the following in Ubuntu 7.10 .
(otherwise I get a message saying missing curl.h)
# apt-get install libcurl4-gnutls-dev
Hope this helps someone the trouble i went into, just to get the http_post_fields function working

The installation guideline is very insufficient. I've installed for Debian lenny/sid with the following step;
apt-get install php5-dev (to enable pecl command)
apt-get install libcurl3 (to get curl support)
apt-get install libmagic
and
pecl install pecl_http
pecl will download and compile but before that just follow the prompt. If the respective development library is not available in your system, the compilation will abort.
After pecl_http got install, copy /usr/lib/php5/20060613+lfs/http.so to /usr/lib/apache2/modules and restart apache
Hopefully this will help others from facing the same hassle for quite sometime.

Don't forget to copy ''http.so'' in the php/modules directory and add ''extension=http.so'' to php.ini.

The "Installation requirements on Windows" are confusing:
If you are a Windows user you need to have the php_curl.dll extension installed before being able to install the php_http.dll extension.
