Manual
floatval(
mixed$value ): float
Gets the float value of value.
Parameters

May be any scalar type. floatval should not be used on objects, as doing so will emit an E_NOTICE level error and return 1.
Return Values
The float value of the given variable. Empty arrays return 0, non-empty arrays return 1.
Strings will most likely return 0 although this depends on the leftmost characters of the string. The common rules of float casting apply.
