PHP is a great language for building web applications. It is essentially a server-side scripting language that is also used for general-purpose programming. PHP 7 is the latest version, providing major backward-compatibility breaks and focusing on high performance and speed. This fast-paced introduction to PHP 7 will improve your productivity and coding skills. The concepts covered will allow you, as a PHP programmer, to improve the performance standards of your applications. We will introduce you to the new features in PHP 7 and then will run through the concepts of object-oriented programming (OOP) in PHP 7. Next, we will shed some light on how to improve your PHP 7 applications' performance and database performance. Through this book, you will be able to improve the performance of your programs using the various benchmarking tools discussed. At the end, the book discusses some best practices in PHP programming to help you improve the quality of your code.

Memcached key-value cache store


According to the Memcached official website, it's a free, open source, high performance, and distributed memory object caching system. Memcached is an in-memory key-value store that can store datasets from a database or API calls.

Similarly to Redis, Memcached also helps a lot in speeding up a website. It stores the data (strings or objects) in the memory. This allows us to reduce the communication with outside resources, such as databases and or APIs.

Note

We are assuming that Memcached is installed on the server. Also, the PHP extension for PHP 7 is also assumed to be installed.

Now, let's play a little with Memcachd in PHP. Take a look at the following code:

//Instantiate Memcached Object
$memCached = new Memcached();

//Add server
$memCached->addServer('127.0.0.1', 11211);

//Lets get some data
$data = $memCached->get('packt_title');

//Check if data is available
if($data)
{
  echo $data;
}
else
{
  /*No data is found. Fetch your data from any where and...
