+ ExplanationThis question tries to attract your attention to a problem that doesn’t bear on its answer. The $array array will contain only one element, since true evaluates to the integer 1. However, there is a typo in the var_dump() statement—$array is misspelled as $aray, using only one ‘r’. Therefore, the var_dump() statement will output NULL (and, possibly, a notice, depending on
your error settings). Answer E is correct.
