PHP & MySQL
For over 20 years PHP & MySQL have been powering increasingly complex websites. They allow sites to be built and maintained without any proprietary licencing.
This has allowed anyone regardless of age, background or experience to begin web-programming without the heavy costs of other systems. Because of this huge influx, the internet and websites are now nearing the stage of replacing desktop applications entirely.
We all here have extensive experience working directly with both PHP & MySQL wherever suitable to solve problems and build solutions.
