Install PHPize on Debain-Ubuntu

Just install a bunch of package-

apt-get install autoconf automake libtool m4
apt-get install php5-dev
apt-get install libcurl3 php5-dev libcurl4-gnutls-dev libmagic-dev
apt-get install php-http make
pecl install pecl_http

And adding "extension=http.so" to php.ini (Normally located at /etc/php5/apache2/php.ini)

Then restart Apache (sudo service apache2 restart).

If in doubt, check your apache logs:
sudo su —
cd /var/log/apache2
tail -25 error.log
