Is chlorophenylmethane the correct IUPAC name rather than chloromethylbenzene?
The preferred IUPAC name is, indeed, (chloromethyl)benzene, built from substitutive prefix chloromethyl. The parentheses around "chloromethyl" are required because it is a compound substituent (a simple substituent attached to another simple substituent, specifically, methyl and chloro in this case). The Blue Book [1, p. 66] has plenty of examples similar to yours:
Note that common names for this molecule also include: benzyl chloride and α-chlorotoluene.

The remark about the use of parentheses is correct. However, the actual question was whether the preferred name is chloro(phenyl)methane or (chloromethyl)benzene.More
@Loong You are right. I was (and still am) too lazy to look up the relevant rules so just decided to edit in a brief line about the parentheses; I leave it to you if you want to expand further or write another answer.More
