merge two arrays have a common key

Question

I have two Json arrays :

$arrayA = array("avg" => '1',"shape" => 'hey');

$arrayB = array("avg" => '2',"shape" => 'trapezoid');

I want to combine them using javascript or PHP as :

arrayAB = {"avg":['1', '2'], "shape":[hey', 'trapezoid']};

It's a really bad idea. You better have nested arrays for similar keys — zerkms, Aug 21 '12 at 04:12
What do you already have tried? Post your code, explain your difficulties, tell what is the context of the problem that you are trying to solve. — davidbuzatto, Aug 21 '12 at 04:12

$arrayA = array("avg" => "234","shape" => "hey");
$arrayB = array("avg" => "5678","shape" => "trapezoid");
$array3 = array();

foreach ($arrayA as $key => $value) {
    $array3[$key] = array($arrayA[$key], $arrayB[$key]);
}

Thanks Flyingude and thanks guys for the quick replies!! I tried This and it worked perfect the way I want it, merge two arrays, group by the keys and display the value : $arrayA = array("avg" => "234","shape" => "hey"); $arrayB = array("avg" => "5678","shape" => "trapezoid"); $arrayAB = array(); foreach ($arrayA as $key => $value) { $arrayAB[$key] = "[".$arrayA[$key].",".$arrayB[$key]."]"; } print_r($arrayAB); ?> Thanks again!! – mongotop Aug 21 '12 at 04:40
