    $dataPoints = array(array('x' => 4321, 'y' => 2364),
                array('x' => 3452, 'y' => 4566),
                array('x' => 1245, 'y' => 3452),
                array('x' => 700, 'y' => 900), 
                array('x' => 900, 'y' => 700));

 $dataPoints = array();    
 $brands = array("COCACOLA","DellChannel","ebayfans","google","microsoft","nikeplus","amazon");

This is because you're re-assigning $dataPoints as a new array on each loop.

Change it to:

$dataPoints[] = array("x"=>$resp['friends_count'],"y"=>$resp ['statuses_count']);

This will append a new array to the end of $dataPoints

Every iteration you're overwriting $dataPoints variable, but you should add new elements to array...

$dataPoints[] = array("x"=>$resp['friends_count'],"y"=>$resp ['statuses_count']);

Hi, use array_merge($array1,$array2) make it simple use two array one for use in iteration and another for storing the final result. checkout the code.

$dataPoints = array();
$dataPoint = array();

$brands = array("COCACOLA","DellChannel","ebayfans","google","microsoft","nikeplus","amazon"); foreach($brands as $value){ $resp = GetTwitter($value); $dataPoint = array("x"=>$resp['friends_count'],"y"=>$resp ['statuses_count']); $dataPoints = array_merge($dataPoints,$dataPoint); }
