Hello, I am trying to process data in php from an sql query as follows:
I pull daily data for a fund, the data includes the date, ticker, volume, AUM (Assets under Management), Flows, Type of Fund, Fund Company ect
Once I have this data I am trying to calculate for example the Weekly data for each fund between the dates i provided for the query for each ticker
so my results look something like
Ticker1 Ticker2 Ticker3 Ticker4
week1 volume volume volume volume
week2 volume volume volume volume
week3 volume volume volume volume
week4 volume volume volume volume
week5 volume volume volume volume
I already can pull all of the weeks from the daily data and dump them into an array, but in php I need to create a multi-dimensional array to contain [ticker][date][volume] so that for each date and ticker I can calculate the volume.
Any thoughts or ideas? Any better ways to do this?
Also, any suggestions as how to loop through the daily data and for each week, for each ticker, get volume from the sql array.
I use while($info = mysql_fetch_array($data)) to loop through my results by row.
Please let me know if you need more info.
Is there maybe a way to calculate this data from SQL instead of trying to process it in PHP?
Thanks soo much!
