gettype( mixed$value ): string

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

Parameters

value

The variable being type checked.

Return Values

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"

Changelog

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