According to the [2015 Stack Overflow Developer Survey](http://stackoverflow.com/research/developer-survey-2015#tech) (26,086 people surveyed), PHP was the 5th most popular/used language at 29.7%.
Ranked in these QuestionsQuestion Ranking
Pro One of the most common languages
According to the 2015 Stack Overflow Developer Survey (26,086 people surveyed), PHP was the 5th most popular/used language at 29.7%.
Pro Lots of tutorials online
Pro Used by most common CMS platforms
Many clients are looking for an easy-to-update web site that's flexible and free. Drupal and Wordpress fill those needs very well.
Pro Most prominent language for web applications
Part of the de facto standard web application stack.
Pro Great third-party package manager
PHP standard library is somewhat subpar, but if you need plugins, language features, composer has them all( you can even puzzle together a custom framework from composer).
Since 7.x was released, PHP has become a pretty fast language.
Pro Lots of PHP frameworks available which help with development
PHP people love frameworks, and with frameworks such as Laravel, you can build a web app or API really fast (Facades, ORMs, scaffolding etc.)
Pro Great documentation
Pro ClojureScript for client-side scripting
Luminus allows using ClojureScript for client-side development. This allows sharing things like validation logic between the server and the client.
Pro Luminus is flexible
Luminus is built on a stack of composable libraries that can be easily swapped to make the application fit the needs of the user. The applications are generated using Leiningen templates and can be initialized with a specific set of features, such as database connections, needed for a specific application.
Pro Good documentation
Luminus provides step-by-step documentation on how to accomplish common tasks.
Pro Simple to setup and use
Luminus is small and flexible. It's geared towards interactive development using the REPL. You can see your changes as you're working without having to restart the application.
Con Poorly designed language
Despite its widespread use, PHP is generally looked upon poorly from a design point of view. The consistency of function names and function argument order, lazily and borderline non-functional implementation of object oriented programming, can only receive requests via POST methods, slow version adoption (the PHP you learn right now may not work on every webserver you'll work on), and a focus on "hacking things together" rather than "doing it right". These are all very common complaints when it comes to working with PHP. While not a bad language to learn, PHP is not at all a good language to learn first, as it will probably teach bad habits.
Con Immense catalog of insecure frameworks
The most serious security problems in websites on the web today are almost universally found in popular PHP frameworks, CMS platforms, libraries and code samples, almost all stemming from poor language design, bad tutorials and awful resources.
Con After python, probably one of the worst languages ever
Con Most tutorials are out of date
A lot of very bad tutorials are still widely circulated among beginners, and these tutorials teach very poor programming practices.
Con Most resources are poorly-written
Few resources exemplify the "correct" or secure use of features.
Con Poorly designed language, awful syntax & luckily on the decline
Nobody in their right mind is using PHP for new software, if you decide to learn it as your first language you'll be stuck working in teams with old developers who have had no interest in the computer programming field since they landed their first job while maintaining some 2000 era archaic website codebase.
Con Interpreter being too permissive
If you forget the dollar sign, the variable name will be converted to a string.
