However, PHP has come into vogue since PHP 5. x with several speed and framework improvements. Python and related languages are good for prototyping, and plotting is easy, and once you've got things working can write the numerical kernels in compiled languages for speed; but it again suffers from the lack of real arrays (Numpy is good, but not . Pros Excellent for general purpose programming Many books and references available on well-tried and tested coding algorithms - no need to re-invent the wheel. PHP is the language of choice for massive projects, especially WordPress itself. Increased security. Function Blocks were originally developed to create a system that you could set up many of the common, repeatable tasks, such as counters, timers, PID Loops, etc. In the technology field, programmers are in high demand with different technical skills like programming, cloud technologies, etc. Lack of user-defined data structures. Now we are on to our third PLC Programming Language. PASCAL is a programming language named after the 17th century mathematician Blaise Pascal.
