Why does the gettype() say it's a double but var_dump() says float?

Answer 2

Directly from PHP.net (gettype()):

Possibles values for the returned string are:

... "double" (for historical reasons "double" is returned in case of a float, and not simply "float") ...

//Main primary code for this Example begins below

//run these examples below in your test PHP file and see the results in your JS console window

//e.g.#1
$code1 = "1212";
console_sn(gettype(floatval($code1)));

//e.g.#2
$code2 = "1212sn";
console_sn(gettype(floatval($code2)));

//e.g.#3
$code3 = "1212";
console_sn(gettype((trim($code3))*1));

//e.g.#4
$code4 = "1212sn";
console_sn(gettype((trim($code4))*1));
