The PECL uploadprogress modules allows a user to see a upload progress bar.
This is a great UI that makes uploading in action and hence good user experience.

To intall uploadprogress module:

1. install php development, pecl, pear, and development tools if you not yet have them installed:

yum -y install php-devel php-pecl php-pear
yum -y groupinstall "Development Tools"

2. install the upload progress:

pecl install uploadprogress

This is what you should get:

[root@xxx]# pecl install uploadprogress

----------------------------------------------------------------------
Libraries have been installed in:
/var/tmp/pear-build-root/uploadprogress-1.0.1/modules</p>

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
