Re: Querying Database to draw a Graph using PHPlot

1. To find errors on database calls, add error handling!
eg minimally ...
$conn = mysql_connect($dbhost,$username,$password) or exit( mysql_error() );
...
$r = mysql_query($query) or exit( mysql_error() );
2. The call to mysql_fetch_array(0 throws uses up a row.
3. Fetch calls need to be contingent on what they return eg ...
while( $r = mysql_fetch_row($r) )
$data[] = mysql_fetch_row($r);
