You can create graphs and charts in PHP using GDChart extension. GDChart comes with the extension. This ext/gdchart extension, in turn, requires you to have GD support compiled into your PHP build. On UNIX systems, this is accomplished by downloading and installing the GD libraries from http://www.boutell.com/gd
After downloading you can install using pecl command
~$ pecl install gdchart
Also you can manually download the source code archive from http://pecl.php.net/package/GDChart and compile it as shown below
~$ cd gdchart-1.2
~$ phpsize
~$ ./configure
~$ make
~$ make install
