How to put a variablevalue into an array

Anon

I posted this q earlier but it looks as though its wiped 🙁

I need to pass the values from a mysql query array into an array for JPGraph to do on the fly graphing for a model car results program.

Is this correct syntax?

$ydata[] = $dbquery['laps'];

ie:
to make up the usual jp coded array which looks like this:

$ydata = array(23.45,34.56,etc,etc)

Help?

Hi,

$dbquery['laps'] should be a single field named laps in your table and not your table name. thus, laps in your example contains a string object and not an array.

$someArray[] = $someVariableOrValue
is incorrect, when using the braces or brackets (or whatever you call it) "[ ]" there should be a some pointer or identifier inside those.

assuming that $dbquery will result to a row with multiple columns,
you probably need something like this:

$dbquery = mysql_query(... your query stmt ...);
$ydata = mysql_fetch_array($dbquery);
// or
$ydata = mysql_fetch_row($dbquery);

OK, I know this is being picky, but in PHP the above is actually correct. For example:
$someArray[] = 3;
Is the same as saying "append 3 to $arr.".

Spot on, this now works a treat.

Thanks a huge lot!

My JpGraphs now feature drivers lap times overlaid on each other just how I wanted it.

Thanks again.
