Inserting/updating an integer field with the number in single quotes

I am using php to insert/update mysql and the code I have automatically puts all parameters in quotes for an insert/update statement etc. I have read elsewhere that this is generally considered bad practice

One of the reasons was that if the integer that is in quotes is in a where clause then the optimiser cant use the index.
However I was wondering if an integer is in quotes in an insert or update statement, will mysql still create/update the indexes on that column properly?

Thanks a lot in advance
