Padding data for sometimes missing object index












0















I have an array where I'm looping on an object



foreach ($product->info->details as $details) {



    $skuItem = $details->dtl1;

    $skuItem = $details->dtl2;

    $skuItem = $details->dtl3;



}


The object it loops on is structured this way



"details": {

  "1": {

    "dtl1": "123",

    "dtl2": "TEst",

    "dtl3": "123"

  },

  "2": {

    "dtl1": "12",

    "dtl2": "Test",

    "dtl3": "153"

  }

},


The thing is, it can only have up to 2 of those sets but sometimes it has only one.



Is there a way to accomodate in my foreach loop so that if there is only one then I can basically 'dummy up' a second set with all zeroes? I'm mapping this to a file and need to make sure I'm at least always mapping all 6 values



So if the object looks like 



"details": {

  "1": {

    "dtl1": "123",

    "dtl2": "TEst",

    "dtl3": "123"

  }


I would want to create my array like 



0 => "123",

1 => "TEst",

2 => "123"

3 => "0",

4 => "0",

5 => "0"

After the foreach, you can pad your array with zero:



foreach ($product->info->details as $details) {

    $skuItem = $details->dtl1;

    $skuItem = $details->dtl2;

    $skuItem = $details->dtl3;

}


Array now contains:



0 => "123"

1 => "TEst"

2 => "123"


Now run:



$skuItem = array_pad($skuItem, 6, 0);


This will add zeros to the end of the array until you get 6 items in it, so the array now contains:



0 => '123'

1 => 'TEst'

2 => '123'

3 => 0

4 => 0

5 => 0


If you want string zero instead, then just pass that as the 3rd arg:



$skuItem = array_pad($skuItem, 6, '0');


Yields:



0 => '123'

1 => 'TEst'

2 => '123'

3 => '0'

4 => '0'

5 => '0'

    Right. If your original object only had one item and you created an array with 3 values, then the pad would expand that to 6. If your original object had two items and you created an array with 6 values, then the pad would do nothing.

  • Ok so I think that makes sense but I found an issue. When I run it, it doesn't fill because I've already put things in the array before this so there's always 6 items basically. Is there a way to check in the loop so that if there's only one then add another set?

You can create a template of what you want and replace with what you create in the loop:



$skuItem = array_replace(array_fill(0, 6, 0), $skuItem);


array_pad is probably better for this trivial example, but consider if you have a variety of values:



$temp = array('x', 'y', 'z', 'x', 'y', 'z');

$skuItem = array_replace($temp, $skuItem);


Or:



$temp = array('x', 'y', 'z');

if(count($skuItem) != 6) {

    $skuItem = array_merge($skuItem, $temp);

}

    – Whisou138
    Jan 18 at 19:21











  • Before the loop just check count($product->info->details). But since you show 3 in each object then if there are 3 in result array then there was 1 if there are 6 then there are 2, etc...

    – AbraCadaver
    Jan 18 at 19:24













  • Can you kind of show how I would use the count to dictate whether or not to add zeroes though?

    – Whisou138
    Jan 18 at 19:30











  • You'll need to be more specific. My first code replaces six 0s with what you generate in the loop. If loop generates three values then they replace the first three 0s, if loop generates six values then all 0s are replaced by what you generated in the loop. You will always have 6 in result.

  • Can you kind of show how I would use the count to dictate whether or not to add zeroes though?

  • You'll need to be more specific. My first code replaces six 0s with what you generate in the loop. If loop generates three values then they replace the first three 0s, if loop generates six values then all 0s are replaced by what you generated in the loop. You will always have 6 in result.

You can create a template of what you want and replace with what you create in the loop:



$skuItem = array_replace(array_fill(0, 6, 0), $skuItem);


array_pad is probably better for this trivial example, but consider if you have a variety of values:



$temp = array('x', 'y', 'z', 'x', 'y', 'z');

$skuItem = array_replace($temp, $skuItem);


Or:



$temp = array('x', 'y', 'z');

if(count($skuItem) != 6) {

    $skuItem = array_merge($skuItem, $temp);

}
