Does the order of columns in a select statement affect query speed?

Question

For example, I have a database like this:

id | fname | lname | sex | age | tel | cell | address

If I do select cell, fname, address, sex instead of doing select fname, sex, cell, address, will that affect the speed of query, in big tables?

I did a quick check in phpmyadmin and it appeared to be taking same time, but I wanted to double check.

Thanks.

That won't make any difference.

However, omitting columns from the SELECT clause will make it run faster since it'll send less data over the network.
