Is there an equivilent of c#\'s #region in PHP?
As everybody has said before, the #region in .Net is actually a Visual Studio feature, not a C# one, but the fact that the C# grammar supports the syntax, allows its usage by any IDE that wants to implement it. Since in PHP, the '#' character is also used for comments, the same can be done by the IDEs. In fact, JetBrains' PhpStorm does it: https://blog.jetbrains.com/phpstorm/2012/03/new-in-4-0-custom-code-folding-regions/
