adding array in PHP

Question

First, im new in PHP so please bear with me.

I just want to add an array with the foreach loop but I can't.

if($size > 0)
    {
        $resultArray = array();

        foreach($result as $hospital)
        {
            if($hospital)
            {

                $temp = array('result' => 'true', 
                'total' => $size,
                'id' => $hospital['id'], 
                'name' => $hospital['name'], 
                'address' => $hospital['address'], 
                'telp' => $hospital['telp']);

                $resultArray = array_merge_recursive($resultArray, $temp);
                //$resultArray = array_splice($resultArray, $i, 0, $temp);
            }
        }

        $this->response($resultArray, 200);
    }

I tried to create a $temp array and merge it to the final result, and finally print that final result ($resultArray) to the response.

The array is successfully merged, but not in the way i want. This is the JSON result :

{"result":["true","true"],"total":[2,2],"id":["1","2"],"name":["test","keyword"],"address":["alamat test","alamat keyword"],"telp":["123456","789"]}

What i want is something like this :

-0 :{
result: "true"
total: 2
id: "1"
name: "test"
address: "alamat test"
telp: "123456"
}

-1 :{
result: "true"
total: 2
id: "2"
name: "test2"
address: "alamat tes 2t"
telp: "789"
}

So the response should be an array with 2 items, and each items has some items.

Please kindly help me, Thanks for your help.

It looks to me like you're trying to append an array, to an array, which can be done quite easily:

$resultArray = array();//outside the loop
//loop
$resultArray[] = array(
    'result' => 'true', 
    'total' => $size,
    'id' => $hospital['id'], 
    'name' => $hospital['name'], 
    'address' => $hospital['address'], 
    'telp' => $hospital['telp']
);

Job done. You could also use the array_push function, but that's a function. Functions equal overhead, and should, therefore be avoided (if it doesn't affect code readability). You use array_merge and array_merge_recursive if you want to combine arrays:

$foo = array(
    array('bar' => 'zar')
);
$bar = array(
    array('car' => 'far')
);
var_dump(
    array_merge(
        $foo,
        $bar
    )
);

The effect of array_merge here is comparable to:

foreach ($bar as $subArray)
    $foo[] = $subArray;

Yesss, this is what i mean, sorry for not using "append" word in the question. I cant accept now, need 4 more minutes
Your answer is the best. And thanks for detailed explanation, very helpful for me

Im not totally sure how you want your final array to be, but this will put it like $resultArray[0] = array( //temparray ) etc..:

if($size > 0){
    $resultArray = array();
    $i=0;
    foreach($result as $hospital){
        if($hospital){
            $temp = array('result' => 'true', 
            'total' => $size,
            'id' => $hospital['id'], 
            'name' => $hospital['name'], 
            'address' => $hospital['address'], 
            'telp' => $hospital['telp']);
            $resultArray[$i][$temp];
            $i++;
        }
    }
    $this->response($resultArray, 200);
}

Yes, your solution is working. Thanks a lot. Its too bad i only can accept 1 question and 1 upvote.

Replace this -

$resultArray = array_merge_recursive($resultArray, $temp);

With this -

$resultArray[] = $temp;
