推荐答案
这来自对PHP7中整数(尤其是八进制)的处理方式所做的更改(与PHP5相对).
This comes from the changes made to how integers, specifically octals, are handled in PHP7 (as oppsoed to PHP5).
来自文档(来自PHP7迁移)
From the documentation (from PHP7 migration)
以前，包含无效数字的八进制文字被无声地截断(0128被视为012).现在，无效的八进制文字将导致解析错误.
Previously, octal literals that contained invalid numbers were silently truncated (0128 was taken as 012). Now, an invalid octal literal will cause a parse error.
摘自整数文档
将它们用作字符串或实际整数
Either use them as strings, or actual integers
$a = array(1, 8, 9, 12); // Integers
$a = array("00001", "00008", "00009", "00012"); // Strings
