I am trying to generate a random 10 digit number and insert this into mysql on page load, so each time the page refreshes or loads there should be a different 10 digit number being inserted into the database, however at the moment it just keeps inserting the same 10 digit number again and again.
Can someone please show me where I am going wrong? Thanks.
