I am using Apache web server and PHP 5 server-side scripting language to produce dynamic web pages for our corporate website. How do I install install php gd support under Apache/PHP5 for dynamically manipulating images?
PHP is used mainly in server-side application software along with various addons.
PHP includes a large number of free and open source libraries with the core build. PHP is a fundamentally Internet-aware system with modules built in for accessing FTP servers, many database servers, embedded SQL libraries such as embedded MySQL and SQLite, LDAP servers, and others. Many functions familiar to C programmers such as those in the stdio family are available in the standard PHP build.
The GD Graphics Library for dynamically manipulating images. You will need to compile PHP with the GD library of image functions for this to work.
However Ubuntu (and Debian) Linux comes with the package called php5-gd. Just type the following command to install this module:
# apt-get install php5-gd
$ sudo apt-get install php5-gd
Sample outputs (from my Debian server)

Finally, restart the Apache 2 web serer, enter:
# /etc/init.d/apache2 restart
You can test your php application.
How do I verify that php5-gd support loaded or not?
Type the following command:
$ php5 -m | grep -i gd
$ php5 -i | grep -i --color gd
$ php -i | grep -i --color gd
Additional .ini files parsed => /etc/php5/cli/conf.d/gd.ini, gd GD Support => enabled GD Version => 2.0 gd.jpeg_ignore_warning => 0 => 0 XAUTHORITY => /var/run/gdm3/auth-for-vivek-ruJHl1/database _SERVER["XAUTHORITY"] => /var/run/gdm3/auth-for-vivek-ruJHl1/database
You can also use the following php code. Create a file called test.php and put in your web server directory i.e. Apache DocumentRoot (such as /var/www):
<?php phpinfo(); ?>
