Is there an equivilent of c#\'s #region in PHP?
Although this is an old thread, but if one is still interested one can set a shortcut to code folding in NetBeans. This answer extends @krtek 's answer. To achieve this follow the steps:
Go to Tools> Options> Editor> Code templates
Click New, enter "cf" as the abbreviation, then enter the following code as the expanded text:
//
${selection line}${cursor}
//
Now, if you select multiple lines of text in the editor, you will get the "light bulb" icon in the margin. Click it, and you'll get the option "Surround with Code folding". Select it, enter a description and you're done.
