Need explanation of the given question For Programming language: PHP Question 3 :

Type System: does the language support built-in data types? If so, what are they and what are their meanings (e.g. int, decimal, double, float each have separate ranges and meanings)? list which of the data types discussed therein are supported by your language and give example code-snippets. Also discuss common operations/usage of each data type (e.g. slicing on list, returning multiple values as tuples from functions, arithmetic operations on numeric types e.g. int/float/....). Is it a strongly/weakly typed language? Is it a dynamically typed language? Is it type-safe? If the language doesnt have any explicit type system (e.g. Python), does it have an implicit type system? Justify your answers. Also discuss some common types used in that language but are not supported as built-in types (e.g. String class in Java). Explain your answers using code-snippets.
