When comparing PHP vs ASP.NET MVC, the Slant community recommends PHP for most people. In the question“What is the best programming language to learn first?” PHP is ranked 32nd while ASP.NET MVC is ranked 48th. The most important reason people chose PHP is:
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%.

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).
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.)
Since 7.x was released, PHP has become a pretty fast language.
The framework has many build-in tools, and many packages have been written targeting the framework.
Pro Cross platform
.Net Core can work on any platform.
Pro Extensive documentation
There are a lot of resources available to get help.
Pro Widely used
It's pretty easy to find a job with it and there's plenty of documentation and tutorials around.
Asp.NET Core on Linux is fast accordingly to TechEmpower benchmarks.
Pro Asp.NET core provides balance between magic/agility and craftsmanship
You can get ordinary details quickly but with complete freedom to make your craft, knowing everything that is happening underneath the cloths. The highly modular system makes it possible to scale small applications to large ones with ease.
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 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.
