Get the type of a variable

Description

gettype(mixed $value): string

Returns the type of the PHP variable value. For type checking, use is_* functions.

Possible values for the returned string are:

"boolean"
"integer"
"double" (for historical reasons "double" is returned in case of a float, and not simply "float")
"string"
"array"
"object"
"resource"
"resource (closed)" as of PHP 7.2.0
"NULL"
"unknown type"

Version	Description
7.2.0	Closed resources are now reported as `'resource (closed)'`. Previously the returned value for closed resources were `'unknown type'`.
