PHP is a general-purpose language but it is mainly used for Web development. It is very popular for small- or medium-level website development compared to other languages. It is also used by some giant firms like Facebook, YouTube and Yahoo! Nowadays, there are a lot of frameworks built on PHP which compete with Python and Perl.
This article contains a list of Top PHP DIY Projects published on electronicsforu.com. These projects can also be used for final-year projects. The list is as follow:

Operational Amplifier Gain And DC Offset Program

Create a Smart software tool using php .This software program does the work for you automatically by taking the required parameters from you, such as reference voltage, required output and input voltage swings. It then outputs a recommended design. You need to choose at least one component value by referring to the datasheet of the op-amp to calculate the rest automatically. Then, you need to find the nearest component values to incorporate in the design.

Wireless Video Surveillance Robot using Raspberry Pi

PHP based GUI controlled robot which can be used for video surveillance & monitoring which can be controlled through a GUI interface. The control mechanism is provided with a video transmission facility. The video transmission is practically achieved through high-speed image transmission. Initially, the robot will be equipped with a camera which will capture the scenes and transfer the images to the server on which the user will be controlling and watching the live feed.

QR Code-Based UI for Vending Machine, ATM and LIFT

PHP based UI to control ATM, vending machines or lifts, contactless systems have become an essential requirement in the market these days. Therefore, we will be making a solution that displays UI on the phone and can be thus used as an input to any device such as ATMs, vending machines, lifts or objects that require contactless interaction.

Operational Amplifier Gain And DC Offset Program

Presented here is a program to find the gain and DC offset values of an operational amplifier (or op-amp). While doing practical electronics experiments, especially in analogue electronics, we come across a very versatile component, that is, the op-amp. It is a low-cost single-chip solution to clumsy and difficult-to-troubleshoot multiple-transistors based designs.

WordPress Web Server Setup on Raspberry Pi

WordPress is a PHP and MySQL based open source blogging platform and content management system. It is a popular blogging system and includes features like threaded comments, galleries, revision histories, trash, custom post types, thousands of themes, widgets and plug-ins. This article describes the setting up of a WordPress web server setup on Raspberry Pi.
