int变量有前导零？ [英] int variable with leading zero?

为什么以下结果是34？
它似乎与八进制数没有任何关系。

Why is it that following results in 34? It doesn't seem to have anything to do with octal numbers.

intval(042);

推荐答案

但前导0表示多种语言的八进制，就像这里的情况一样。

but a leading 0 does indicate octal in many languages, as is the case here.
