<?php
    // gettype(mixed $value): string

    // 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"
?>
