1. Brief overview
PHP was developed in 1994 by Rasmus Lerdorf. PHP stands for Hypertext Preprocessor. It is an open-source scripting language for back-end development; it received global identification. In W3techsurvey, 79% of all websites use PHP. The most popular websites are Facebook, Wikipedia, and WordPress.
2. Performance & Speed
You can combine PHP with HTML only. The greatest advantage of PHP is the availability of CMSs like WordPress or Drupal. These solutions facilitate and even make web development cheaper. You can also extend PHP with any LAMP stack technology and such server solutions as MySQL or PostgreSQL.
PHP is a back-end development language only. PHP belongs to the LAMP stack, which stands for Linux, Apache, MySQL, and PHP/Perl/Python. To develop a web application with this technology stack, a software engineer needs to know four different syntax systems and HTML and CSS. Switching between languages is neither easy nor efficient, which complicates the learning loop badly.
PHP uses dollar signs “$” to denote variables, whereas JS has no such sign. All variables are local by default unless declared global with global. A local variable will not be available in subfunctions unless you pass it in an argument. In PHP, addition is done with “+,” and concatenation is done with. “. PHP is case-sensitive only in variables. PHP allows both numeric and associative arrays. In PHP, arrays and objects are completely different things with different syntax. In PHP, items in objects are referenced with an arrow “->.”
In JS, variables are global by default unless declared local with var. A local variable is available for everything within this function or its subfunctions. In JS, both addition and concatenation are done with “+.” JS is case-sensitive in variables and functions. There are no associative arrays (key-value pairs) in JS; you should use JSON strings instead. In JS, arrays and objects are very similar and often interchangeable. An object item can be referenced as an array item as well. In JS, items in objects are referenced with a full stop “.”.
6. Apps it is best suited for
Although PHP is a general-purpose programming language, it is primarily used for developing dynamic web pages. Considering the availability of PHP-based content management systems such as Moodle and WordPress, PHP is the best solution for blogs, learning management systems, and e-commerce websites.
