1. Install the PEAR framework

sudo get install php-pear


2. Restart apache

sudo /etc/init.d/apace2 restart


3. Install a PEAR package (optional)

sudo pear install Net_Ping-2.4.5


You can install any PEAR package using this command but in this example we'll install the Net_Ping package

4. Here's a sample PHP code to use the Net_Ping package (optional)

require_once "Net/Ping.php";
$ping = Net_Ping::factory();
 
$host = 'ubuntututorials.net';
$count = 3;
 
if (PEAR::isError($ping))
{
    echo $ping->getMessage();
}
else
{
    $ping->setArgs(array('count' => $count));
    $res = $ping->ping($host);
    foreach ($res->_raw_data as $line)
    {
        echo $line . "\n";
    }
}


This code will ping the host ubuntututorials.net three times and echo the results

1. Download ionCube loaders

sudo wget http://downloads.ioncube.com/loader_downloads/ioncube_loaders_lin_x86.tar.gz


2. Extract

sudo tar zxvf ioncube_loaders_lin_x86.tar.gz


3. Move to a permanent location

sudo mv ioncube /usr/local/


4. Add reference to your php.ini file (sudo pico /etc/php5/apache2/php.ini)

zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.2.so


There are a few versions of the loader in the tar archive. Use the one that matches your PHP version.

5. Restart apache

sudo /etc/init.d/apache2 restart


1. Download a copy of Zend Optimizer / Guard from the location below and put it into /tmp

http://www.zend.com/en/products/guard/downloads


2. Extract

cd /tmp
sudo tar zxvf ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz


Replace with your actual filename

3. Create a directory to contain Zend optimizer

sudo mkdir /usr/local/lib/Zend


3. Move the Zend optimizer lib to a permanent location

sudo mv ZendOptimizer-3.3.9-linux-glibc23-i386/data/5_2_x_comp/ZendOptimizer.so /usr/local/lib/Zend/


Your ZendOptimizer directory name may be different since it includes version numbers and platform. I'm using the 5_2_x_comp directory because I have PHP 5.2 installed.

4. Add reference to your php.ini file (sudo pico /etc/php5/apache2/php.ini)

zend_extension = /usr/local/lib/Zend/ZendOptimizer.so
zend_optimizer.optimization_level = 15


5. Restart apache

sudo /etc/init.d/apache2 restart
