+ AnswerA

+ ExplanationThe script will output 1 (Answer A). This is because only integer numbers and strings can be used as keys of an array—floating-point numbers are converted to integers. In this case, both 0.1 and 0.2 are converted to the integer number 0, and $array will only contain the element
0 =>'b'.
