Only last item added to array

I have the following PHP code. It iterates through an array which contains two items in item["type] and two items in item["count(*)"]

However, when I add the items to the arrays, only the last ones are added. What am I doing wrong?

$behTypes = array();
$behValues = array();
foreach($behaviours as $item){
    $behTypes = $item["type"];
    $behValues = intval($item["count(*)"]);
}
echo($behTypes);
echo($behValues);

To add an element to an array in PHP, use the [] syntax on the array. This syntax behaves identically with array_push(). To quote the documentation...

array_push() treats array as a stack, and pushes the passed variables onto the end of array. The length of array increases by the number of variables pushed. Has the same effect as:

<?php
$array[] = $var;
?>

Here is the fix applied to your code...

$behTypes = array();
$behValues = array();
foreach($behaviours as $item){
    $behTypes[] = $item["type"];
    $behValues[] = intval($item["count(*)"]);
}
echo($behTypes);
echo($behValues);

you need to push items into array.

$behTypes = array();
$behValues = array();
foreach($behaviours as $item){
    array_push($behTypes, $item["type"]);
    array_push($behValues, intval($item["count(*)"]));
//OR
    //$behTypes[] = $item["type"];
  //  $behValues[] = intval($item["count(*)"]);
}
print_r($behTypes);
print_r($behValues);

    $behTypes[] = $item["type"];
    $behValues[] = intval($item["count(*)"]);
}
echo($behTypes);
