PHP5 - Scripting Language installation on ubuntu


Installation

The PHP5 is available in Ubuntu Linux. Unlike python and perl, which are installed in the base system, PHP must be added.

  • To install PHP5 you can enter the following command in the terminal prompt:

    sudo apt-get install php5 libapache2-mod-php5
    

     

    You can run PHP5 scripts from command line. To run PHP5 scripts from command line you should install php5-cli package. To install php5-cli you can enter the following command in the terminal prompt:

    sudo apt-get install php5-cli
    

     

    You can also execute PHP5 scripts without installing PHP5 Apache module. To accomplish this, you should install php5-cgipackage. You can run the following command in a terminal prompt to install php5-cgi package:

    sudo apt-get install php5-cgi
    

     

    To use MySQL with PHP5 you should install php5-mysql package. To install php5-mysql you can enter the following command in the terminal prompt:

    sudo apt-get install php5-mysql
    

     

    Similarly, to use PostgreSQL with PHP5 you should install php5-pgsql package. To install php5-pgsql you can enter the following command in the terminal prompt:

    sudo apt-get install php5-pgsql
    

     

Configuration

Once you install PHP5, you can run PHP5 scripts from your web browser. If you have installed php5-cli package, you can run PHP5 scripts from your command prompt.

By default, the Apache 2 Web server is configured to run PHP5 scripts. In other words, the PHP5 module is enabled in Apache2 Web server automatically when you install the module. Please verify if the files /etc/apache2/mods-enabled/php5.conf and/etc/apache2/mods-enabled/php5.load exist. If they do not exists, you can enable the module using a2enmod command.

Once you install PHP5 related packages and enabled PHP5 Apache 2 module, you should restart Apache2 Web server to run PHP5 scripts. You can run the following command at a terminal prompt to restart your web server:

sudo service apache2 restart 

 

Testing

To verify your installation, you can run following PHP5 phpinfo script:


You can save the content in a file phpinfo.php and place it under DocumentRoot directory of Apache2 Web server. When point your browser to http://hostname/phpinfo.php, it would display values of various PHP5 configuration parameters.
