PHP is a scripting language that most programmers used when creating and designing websites. It is an interpreted language wherein program processing is already in progress and codes are read, interpreted, and processed instantly. As a beginner on this subject, you need to learn the basics and one of the first things that you need to do is to fully understand the most common words used when discussing about this subject matter.
Scripting language is among the most commonly used words. This is the system that most programming languages are created when reading and processing programming codes. Similar to PHP, it uses basic tags during the programming process, having start tags and end tags in every code. These tags serve to notify the interpreter about the presence of certain programming codes that are inserted within the tags.
The next important word that you need to learn its definition is the PHP Interpreter. This is the processing engine that is usually built-in and a fragment of the whole programming language that reads, interprets, and processes the codes written by the programmer. This processing engine runs quietly behind the scenes, reading codes, processing the recently written instructions, and then finally executing the command. Scripting tags are used to direct the interpreter to where to start and when to stop reading codes and processing them.
Take note that the written codes are the program itself. Hence, you need to be perfect as possible when writing codes in order for the program to run smoothly without any flaw. One false move in your writing of codes, such as omission to place end tags, and your program may no longer be able to run. Hence, you need to be extra careful with writing codes and try to review them always to ensure that everything goes on smoothly and perfectly.
Bear in mind the program, or your written codes, may have hundreds and thousands of line. Regardless of the numerous numbers of lines, you need to ensure the placement of vital start tags so that the interpreter can read your codes. Similarly important, every start tags must always have an end tags and any open tags may result to several issues and errors on your programming.
Take note of all these things when it comes to PHP. These are among the most important things that you need to always remember to ensure success in your programming.
