Cara menggunakan introspection in php geeksforgeeks

The introspection functions are rarely used when building a stylesheet. However, they are valuable if something does not work properly - to figure out what's going on: like debugging functions.

The following table lists all introspection functions in Sass:

FunctionDescription & Examplecall(function, arguments...)Calls a function with arguments, and returns the result.content-exists()Checks whether the current mixin was passed a @content block.feature-exists(feature)Checks whether feature is supported by the current Sass implementation.

Example:
feature-exists("at-error");
Result: true

Example:
function-exists("nonsense")
Result: false

Example:
variable-exists(a)
Result: true

Example:
mixin-exists("important-text")
Result: true

Example:
type-of(15px)
Result: number
type-of(#ff0000)
Result: color

Example:
unit(15px)
Result: px

Example:
unitless(15px)
Result: false
unitless(15)
Result: true

Example:
variable-exists(b)
Result: true

The term PHP is an acronym for PHP: Hypertext Preprocessor. PHP is a server-side scripting language designed specifically for web development. It is open-source which means it is free to download and use. It is very simple to learn and use. The files have the extension “.php”. 

Rasmus Lerdorf inspired the first version of PHP and participated in the later versions. It is an interpreted language and it does not require a compiler.
