A person who designs the logic for and writes the lines of codes of a computer program. Programming is the heart and soul of developing computer applications, and programmers are the most misunderstood people in the business.

They are constantly being criticized for taking longer to write a program than they initially estimated. A programmer or software developer is someone who programs computers, that is, one who writes computer software.

The term computer programmer can refer to a specialist in one area of computer programming or to a generalist who writes code for many kinds of software. One who practices or professes a formal approach to programming may also be known as a programmer analyst, software engineer, computer scientist, or software analyst.

A programmer's primary computer language (Java, C++, etc.) is often prefixed to the above titles, and those who work in a web environment often prefix their titles with web.

Programmers work in many settings, including corporate information technology departments, big software companies, and small service firms. Many professional programmers also work for consulting companies at client' sites as contractors. Licensing is not typically required to work as a programmer, although professional certifications are commonly held by programmers. Programming is widely considered a profession (although some authorities disagree on the grounds that only careers with legal licensing requirements count as a profession).

Those proficient in computer programming skills may become famous, though this regard is normally limited to software engineering circles. Many of the most notable programmers are often labeled hackers.

Programmers often have or project an image of individualist geekdom, resistance to "suits" (referring to both business suits literally and figuratively to the "Establishment"), controls, and unionization.

It is very difficult for people who have not spent any time programming to understand why programmers are often the world's worst estimators. Programming is very creative, and after a program is put into production, programmers derive a sense of completion that is very satisfying.

Thus, the more programs programmers write, the more confidence they have. As a result, they take on what seems like an eternal optimism that the job can be done easily. As their confidence builds with experience, it often seems their estimates are even more absurd. It takes numerous hard knocks to wise up and then double, triple or even quadruple one's initial estimate in order to put reality into it.

Php programmer: PHP (Hypertext processor) is a programming language used by web developers to create dynamic web content which actively interact with databases.

Web programmer: A web programmer is responsible for programming the functionality of a web site. So while a requirements analyst is tasked with determining what a web site should do, the web programmer figures out how it is going to do it and then writes the necessary programming code.
