如何在mongoDB中存储零前导数字

Question

I want to store numbers like 09876 in mongoDb

I'm using php driver and so far I was casting my numbers to (int) , but I just noticed the numbers which starts with Zero , not saving in mongo properly and the zero drops !

So my numbers in mongo are like : NumberLong(9876) but it must be : NumberLong(09876)

So I know I can cast my numbers to String and save them exactly as they are , but is there a way beside this ?

I mean , I dont want to store numbers as Strings in mongo db

something like casting to char ???

Answer 1

Numbers are stored as values and any leading zeroes will ALWAYS be dropped in numeric fields. You have 2 options:

1. Store it as text.
2. Format it before displaying to add the zeroes.
