Question

See like here is a Table named play .

Name , Key , count
ball , 02322, 002
bad , 00121, 008
bin ,91123, 001

like you can see the count evry time when any key runs i have to count it in there so in that case i have to read the current value and then add and update it to the table . is ther any easier ways ?

Answer 1

You can use an UPDATE query for that. It’s usually something like:

 db("UPDATE `play` SET count=(count+1) WHERE key=?", $key);

The SET clause allows to use an expression to be assigned to the column.
