Nubmber starting from 0 are interpreted as octal constats.

Since 8 and 9 are not a valid digits in octal, 08 and 09 are invalid numbers and both interpreted as just 0. “08” is string and even in case of arithmetical operations, will be interpreted as normal decimal integer:

"echo '08'+'08'; // 16

Hence using strings should be safe for your case.
