Adding a new array to a multidimensional array item

Question

I need to add some details to an array without overwriting the old data.

At the moment I have something like this if I print_r($data)

 Array
 (
   [one] => Hello
   [two] => Hello World
 )

I then have a function that adds some data to the array

 foreach ($rubric as $rs){
      if($rs['position']==1){$data['one']=$rs;}
  if($rs['position']==2){$data['two']=$rs;}
 }

This gives me the following if I print_r($data)

Array
(
   [one] => Array
      (
         [id] => 1
      )
   [two] => Array
      (
         [id] => 2
      )
)

Does anyone have any ideas

What I would like to do is....

 foreach ($rubric as $rs){
      if($rs['position']==1){$data['one']['details']=$rs;}
  if($rs['position']==2){$data['two']['details']=$rs;}
 }

With the aim of adding a new subarray called "details" within each array item...

Does that make sense? If I try to run that code however I get the following error

A PHP Error was encountered Severity: Notice Message: Array to string conversion

Could someone tell me what I'm doing wrong?

I find this question to be unclear. I don't see a clear minimal reproducible example. — mickmackusa

See, array_push array_unshift.

Array push puts an element at the end. Array unshift adds a number to the beginning of the array.

You can also use the structure

$myArray['nameOfNewElement']=$newElement;

This adds $newElement to the array $myArray;

Thats what I'm trying to do... that would be prefect but when I try to do that I get "A PHP Error was encountered Severity: Notice Message: Array to string conversion" Any ideas?

The previous syntax I put in was a little more advanced, so I changed it. What's in there now should work.

You can use array_merge.

According to your question, here is the solution :

// sample array
$rubric = array(0=> array("position"=>1),1 => array("position"=>2));
$data = array("one" => "Hello","two" => "hello world");
foreach ($rubric as $rs){
      if($rs['position']==1){
           $d= array_merge($data,$rs);
      }
      if($rs['position']==2){
          $d= array_merge($data,$rs);
      }
 }
print_r($d);

Here is the working DEMO : http://codepad.org/rgKiv542

Hope, it'll help you.

When you write $data['one'] = $rs;, you are assigning $rs to overwrite the value "Hello".

Perhaps what you were trying to do is

$data['three'] = $rs['id'];
