Key ways to use web app with PHP + MySQL

Almost 70% of websites are built on PHP and MySQL on the Internet. While creating a web application for PHP and MySQL sites, one needs to be well prepared in advance to accommodate higher traffic and scale their website. For this, scalability codes and effective handling of traffic are the first things to be looked into while developing a website in PHP.

Some of the key ways to use web apps with PHP and MySQL are listed below:

Take stock of the performance and scalability

Performance levels on websites are judges by the speed with which the data is served to its end users by a website. Scalability refers to the quality of your web pages which is capable of handling any amount of traffic thrown in its direction. To use your web apps well, you need to look at both these aspects on a PHP and MySQL site.

Tune up your PHP site

PHP is a scripting code and recompile the code on each request. To tune up your PHP web page, you can install an opcode cache. This will simplify your work since an opcode cache will circumvent this limitation by pulling the already compiled version, thereby saving time and effort.

The popular opcode caches available are ZendServer and WinCache for the Windows platform and APC cache for the open source. Installing these opcode caches will ease your PHP tuning and increase the performance of your web pages.

Remove dynamic content from your web pages

More often than not, web applications come with pages that are generated by PHP but do not undergo any change. For instance, an FAQ page or a press release statement can be cached to reduce the number of CPU cycles for this task. To achieve this, an easy way is to pre-generate HTML pages from your PHP and then allow the HTML pages to be served directly to the end users. Another way is to make use of template forming systems such as Smarty, which can automatically capture the content into a buffer or a database and then served as a cached copy to the end user. Alternatively, you can write the code yourself.

Look into the load balancing aspect

Load balancing in PHP is a concept that uses a central point for the arrival of all requests and then distributing these request in a balanced way to various web servers. This is an important aspect to be kept in mind while creating web applications that require multiple servers. The load balancing comes in three different operational categories. These are software balancers, hardware balancers and cloud based solutions. All these have the ability to cache the data and load balance the data by random selection or through perception from health meters. There are many applications available to help you in load balancing of data on the PHP platform.

Use Master-Slave Replication of MySQL

Once the Web server set up is adequately scaled, the next thing to expect in most Web applications is the huge database present on MySQL. This creates a traffic jam of data and it is better to be prepared for such a scenario. This bottle neck can be prevented by using a built-in solution on MySQL known as master-slave replication. You can then set up one more MySQL server that obeys all the orders from the master server and simplifies the handling of large amounts of data. All changes should be made on the master server for the changes to be accepted.

These are some of the ways to make use of web applications in a proper way on the PHP and MySQL platforms. There are many more such tips and tricks as every application requires a different treatment in PHP and MySQL. Following these simple rules will definitely ease your working and allow a smooth work flow of your innovative Web apps on the PHP web pages.
