PHP is a short abbreviation of “PHP: Hypertext Pre-processor”. It is one of the Best backend Programming language widely-used, free, and open-source scripting language. PHP scripts are executed on the server directly.
According to a survey of w3techs, the PHP system has been developed into a lone schematic plan that operates and executes almost 80% of websites with server-side programming.
The renowned sites that are being driven through PHP consist of all types of WordPress sites, Facebook, and Wikipedia. Stats reveal that WordPress runs almost 35% of the web. Facebook also use PHP to carry out a various number of languages (with all limitations & warnings) along with its JIT-compiled version of PHP called HHVM.
Various hosting companies also admire the PHP system; a lot of them provide their clients with PHPMyAdmin for managing databases of MySQL.
History of Back-end Programming language
Lerdorf(Danish-Canadian programmer) was born in Greenland and grew up in Denmark & Canada. A well-known name in writing PHP languages, he worked at Yahoo! (a big PHP user) and Etsy. He executes and drives PHP for his own use. In a 2017 talk, he said that “In 1993 programming the web sucked”.
It was Computer Generated Imaginary written in C language, and he said that “you had to change the C code and recompile even for a slight change”.
According to him, Perl (a family of two high-level dynamic programming languages)was “slightly better”, but “you still had to write Perl code to spit out HTML. I didn’t like that at all. I wanted a simple templating language that was built into the web server.”
People wanted to do everything in the stupid little templating language I had written, all their business logic
The pioneering thought of the Danish-Canadian programmer was that the developers still used to write most of their web applications in C language but “just use PHP as the templating language.”
Lerdorf said, however, nobody tried to write C on their own, and people “wanted to do everything in the stupid little templating language I had written, all their business logic.”
Lerdorf opened a sort of battle with untimely web developers just when PHP developed, with the developers that were asking for more & more features. At the same time, he tried to direct them towards other languages for what they wanted to write and execute.
“This is how we got PHP,” a templating language with business logic features pushed into it.”
The web’s Operating Machine
According to Lerdorf (The Founder of PHP), this is the access of PHP, which drives almost 2 billion sites on 10 million physical machines. Thereby improving competence in PHP 7, it had a considerable impact on global energy consumption. Consequently, it has other positive results as well. Moving the world trend from PHP 5.0 to PHP 7, it would save almost 15B kW hours per year and 7.5B kg less carbon dioxide production. He said that forgetting possibly that any unexploited cycles would soon be taken up by machine learning and AI algorithms.
PHP is the operating machine of the web, but it’s not trendy. This Backend Programming Language is uncomplicated, simple to use. But its progressive and lenient nature makes it reachable to developers of any level of skill; so that there is an abundance of spaghetti code out there. It also results in quick hacks that developed into more significant projects. In particular, the new PHP code was flat to SQL injection bugs as developers used to fill input from web forms directly into SQL statements. The world should be thankful for a feature called register_global that was on, by default and that will “insert your scripts with all sorts of variables,” according to its own credentials.
There were no formal plans for PHP from the beginning, and it is still considered as a continual work. It is not a language that has been complied, and object orientation was secured, rather than being designed from the beginning as in Java or C or Ruby. Outdated PHP versions are all over the internet on the basis that as long as it works, nobody touches it. It has become the language that everyone executes and uses, but nobody talks about it.
In a talk of 2002, Lerdorf said that “PHP is not very exciting and there is not much to it”.
PHP ( Backend Programming Language ) has hardly ever got a mention in the analysis by regularly coming fourth as the most popular language in the Redmonk rankings.
According to that, reasons for PHP’s reputation and prolonged existence are its durable qualities. Even though it is a community project with thousands of contributors, some of credit and contribution goes to Lerdorf himself, who continued to maneuver PHP with wisdom and facts. It lacks corporate belongings and has always been free and open-source for all. Lerdorf announced his first broadcast that “The tools are in the public domain distributed under the GNU Public License. Yes, that means they are free!”
A PHP script can be placed anywhere in the file.
- A PHP script starts with <?php and ends with ?>
- The default file extension for PHP files is “.php”.
- A PHP file usually contains HTML tags and some PHP scripting code.
- In PHP, keywords (if, else, etc.) are not case sensitive.
- PHP statements always terminate with a semicolon (;).
In the following example, all three echo statements are equal and legal:
There are many references and user contributions present on the documentation site; everyone finds and admires something remarkable and useful things there. The key point is that PHP is consistent and lightweight, which means it has robust performance in real-world use even if it has not been in the top machine languages.
