Using PHP Cache to Develop a Faster Website
Customer engagement, conversion and website performance is highly important for your site and for that you have to have a faster website so that the customers are not left waiting. Since the human attention span is infamously shorter than the memory span of a goldfish, it is important to offer them what they are looking for within that moment. If you have a dynamic website which is built on PHP web development, and you have a growing website and audience base, then there might be a problem with the website’s performance. Without any proper caching mechanism, the site will become slow and in case your site gets more traffic, the webserver won’t be able to handle.
Now the question is what should you do to have a faster website? There are various methods to have a faster website and each comes with its own advantages and disadvantages. Here in this blog, we will discuss about PHP cache and how it can be used to develop a faster website.
Why do You Need a PHP Cache for Your Website?
Caching a dynamic website page is crucial. With PHP web application development, many times the cache is overlooked and in a website, even a nanosecond performance improvement can bring a lot of changes. If your site depends on the traffic of the search engines, then the cache should be the foremost priority and even Google considers the pages that have a high speed which is a crucial aspect.
Without caching the dynamic site won’t be able to handle a lot of visitors as all the database queries and PHP script executions will use the CPU power and the RAM memory. Since the resources are limited, the web server and the site will become very slow with more traffic or will become unavailable.
By caching, the contents of a web page are stored temporarily in locations that are closer to the users in the same way our memory works. It therefore speeds the content downloads and helps to deliver a faster and more satisfying experience to the users. Caching is one of the most popular website performance optimization techniques.
Types of PHP Cache that a PHP Development Company Uses?
There are different types of cache used and all have them have various functions. The list includes server side cache types that are used with PHP scripts. Some other cache types include browser cache, database cache, proxy cache and etc.
Full Page Caching:
Page caching is the most important type of PHP cache and as the name suggests, the whole PHP web page will be cached in this case. The cached page version is actually stored for some time on the server and when the particular page is searched, it is delivered without delay.
If you have a new project in hand, then you should consider using a modern PHP development framework like the Symphony, Yii, CodeIgniter or Zend. All the frameworks offer their own PHP cache plugin and if you choose any one framework, then you don’t have to write all the codes as the libraries are already bundled. You don’t have to choose all the libraries yourself and most of the PHP cache components are able to cache whole PHP pages.
While caching the entire page, it happens on the entire file system, but with the object cache, things are different and it is mostly used to store the strings, database result sets, array objects. These objects are stored in the RAM and sometimes in the database.
