Hello all,
I am having trouble setting array data from within a MySQL results
query. I have modified data from the result and wish to enter it into
it's own array ($data). That then is used to generate a graph. The
following code basically gives me an empty array...
I am pulling out a timestamp and signal strength from a live data stream
to chart how strong a tower's signal is during the day. The data streams
once a minute from several sources. I compare each incoming signal with
the if statement and keep the highest signal strength. Each row is then
put into the new array.
CODE:
$data = array();
while ($row1 = mysql_fetch_row ($queryexe1)){
$datetime = $row1[2];
$sig1 = $row1[3];
$sig2 = $row1[6];
$sig3 = $row1[9];
list($date,$time) = explode(" ",$datetime);
if ($sig1 > "-150") { $aval = "$sig1"; }
if ($sig2 > "-150") { $bval = "$sig2"; } if ($bval > $aval)
{$aval = bval;}
if ($sig3 > "-150") { $bval = "$sig3"; } if ($bval > $aval)
{$aval = $bval;}
$data[] = array('$time' => '$time','$aval' => 'aval');
$aval = "-999";
}
$graph->SetDataValues($data);
END CODE:
