I have a database, all the data is numbers. I want to make a query that
will extract the data and then make it available in an array, so the
array is populated 'real-time'. I could just enter the number into an
array manually, but I want to automate the job. I don't know what to
start looking for, the 3 books I have either don't talk about this or I
just am missing it.
Could someone point me in the right direction?
This class makes it possible to return an array in two ways very easy.
Just try this
$db = new Ms_db;
$db-connect(true); // open a persistant connection
$vars1 = $db-query(SELECT * FROM table);
$vars2 = $db-query(SELECT * FROM table,off);
$vars1 is now build this way
$vars1[row][column] contains the required value...
$vars2[column][row] contains the required value...
Maybe this helps:
