                      <p>
 
91
      To install PHP5 you
 
92
      can enter the following command in the terminal prompt:
 
93
 
 
94
</p>
 
95
                      <pre class="screen">
 
96
<span class="command"><strong>sudo apt-get install php5 libapache2-mod-php5</strong></span>
 
97
</pre>
 
98
                      <p>
 
99
</p>
 
100
                      <p>You can run PHP5 scripts from command line. To run PHP5 scripts 
 
101
      from command line you should install
 
102
      <span class="application"><strong>php5-cli</strong></span> package. To install
 
103
      <span class="application"><strong>php5-cli</strong></span> you can enter the following
 
104
      command in the terminal prompt:

109
                      <p>
 
110
</p>
 
111
                      <p>
 
112
      You can also execute PHP5 scripts without installing PHP5 Apache
 
113
      module. To accomplish this, you should install
 
114
      <span class="application"><strong>php5-cgi</strong></span> package. You can run the
 
115
      following command in a terminal prompt to install
 
116
      <span class="application"><strong>php5-cgi</strong></span> package:
 
117
</p>
 
118
                      <pre class="screen">
 
119
<span class="command"><strong>sudo apt-get install php5-cgi</strong></span>

</pre>
 
121
                      <p>
 
122
      </p>
 
123
                      <p>To use <span class="application"><strong>MySQL</strong></span> with PHP5 you should install
 
124
      <span class="application"><strong>php5-mysql</strong></span> package. To install
 
125
      <span class="application"><strong>php5-mysql</strong></span> you can enter the following
 
126
      command in the terminal prompt:
 
127
</p>
 
128
                      <pre class="screen">
 
129
<span class="command"><strong>sudo apt-get install php5-mysql</strong></span>

</pre>
 
131
                      <p>
 
132
</p>
 
133
                      <p>Similarly, to use <span class="application"><strong>PostgreSQL</strong></span> with PHP5 you should install
 
134
      <span class="application"><strong>php5-pgsql</strong></span> package. To install
 
135
      <span class="application"><strong>php5-pgsql</strong></span> you can enter the following
 
136
      command in the terminal prompt:

156
          Once you install PHP5, you can run PHP5 scripts from your web
 
157
          browser. If you have installed
 
158
          <span class="application"><strong>php5-cli</strong></span> package, you can run PHP5
 
159
          scripts from your command prompt.
 
160
          </p>
 
161
                <p>
 
162
          By default, the Apache 2 Web server is configured to run PHP5
 
163
          scripts. In other words, the PHP5 module is enabled in Apache2
 
164
          Web server automatically when you install the module. Please
 
165
          verify if the files
 
166
          <code class="filename">/etc/apache2/mods-enabled/php5.conf</code> and
 
167
          <code class="filename">/etc/apache2/mods-enabled/php5.load</code>
 
168
          exist. If they do not exists, you can enable the module using
 
169
          <span class="command"><strong>a2enmod</strong></span> command.
 
170
          </p>
 
171
                <p>Once you install PHP5 related packages and enabled PHP5
 
172
          Apache 2 module, you should restart Apache2 Web server to run
 
173
          PHP5 scripts. You can run the following command at a terminal
 
174
          prompt to restart your web server:
 
175
</p>
 
176
                <pre class="screen"><span class="command"><strong>sudo /etc/init.d/apache2 restart</strong></span> </pre>

188
                <p>To verify your installation, you can run following PHP5
 
189
          phpinfo script:
 
190
          </p>
 
191
                <pre class="programlisting">

196
                <p>
 
197
          You can save the content in a file
 
198
          <code class="filename">phpinfo.php</code> and place it
 
199
          under <span class="command"><strong>DocumentRoot</strong></span> directory of Apache2 Web
 
200
          server. When point your browser to
 
201
          <code class="filename">http://hostname/phpinfo.php</code>, it would
