Count Total Indexes of Array in PHP

Question

I have an array with the following structure:

    Array
    (
        [DigitalAssets] => Array
    (
        [0] => Array
            (
                [PartNumber] => 0276S-4
                [Link] => https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0576s-4.jpg
                [AssetTypeCode] => P04
                [FileName] => 0576s-4.jpg
                [RecordModifiedDate] => 2020-05-13T18:59:10.28
            )

        [1] => Array
            (
                [PartNumber] => 0437S-4
                [Link] => https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0437s-4.jpg
                [AssetTypeCode] => P04
                [FileName] => 0437s-4.jpg
                [RecordModifiedDate] => 2020-05-13T18:59:11.687
            )

        [2] => Array
            (
                [PartNumber] => 0574S-4
                [Link] => https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0574s-4.jpg
                [AssetTypeCode] => P04
                [FileName] => 0574s-4.jpg
                [RecordModifiedDate] => 2020-05-13T18:59:12.593
            )

I want to count the total Indexes of array so that I will run loop accordingly. I used Count($array) and Count ($array,RECURSIVE) but it cannot return the correct total number of indexes.

Can only guide that how to do this?

Thanks

What exactly do you want to count? The number of nested elements, the number of elements in DigitalAssets? You also could use foreach() instead. — Nigel Ren

You have an array nested into an array here. Your outer level only has one entry, that under the key DigitalAssets. And the array under that key than in turn has multiple entries, which you can count with a simple count() … you just need to move to the correct level first. — C3roe

Yes I want to count the total index numbers in DigitalAssets Array. — Eshban Bahadur

What, the mere counting? That has already been answered. And if you just want to loop over all times, then you don’t necessarily need to count them first, you can also use a foreach loop, as Nigel already said. (All in all, this is stuff you should be learning from a beginner tutorial, rather than ask about here.) — C3roe

If You want to count DigitalAssets direct children You can do this count($array['DigitalAssets'])

Here are some tests how count should work.

Code is:

$test = array
        (
            'DigitalAssets' => array
            (
                0 => array(
                    'PartNumber' => '0276S-4',
                    'Link' => 'https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0576s-4.jpg',
                    'AssetTypeCode' => 'P04',
                    'FileName' => '0576s-4.jpg',
                    'RecordModifiedDate' => '2020-05-13T18:59:10.28'
                ),
                1 => array(
                    'PartNumber' => '0437S-4',
                    'Link' => 'https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0437s-4.jpg',
                    'AssetTypeCode' => 'P04',
                    'FileName' => '0437s-4.jpg',
                    'RecordModifiedDate' => '2020-05-13T18:59:11.687'
                ),
                2 => array
                (
                    'PartNumber' => '0574S-4',
                    'Link' => 'https://1ddf4b1b856a39e33863-d785dc0e3b62b5e0ef07f55db00b0659.ssl.cf2.rackcdn.com/Holley/0574s-4.jpg',
                    'AssetTypeCode' => 'P04',
                    'FileName' => '0574s-4.jpg',
                    'RecordModifiedDate' => '2020-05-13T18:59:12.593'
                )
            )
        );

        echo count($test['DigitalAssets'])." ".count($test['DigitalAssets'], 0)." ".count($test['DigitalAssets'], 1);
        exit();

Result in my case: 3 3 18

This means taht in my case mode in count is set to 0 by default so i will get only first level counted. If i set mode to 1 i will get all nested items counted as well. This should clear things up for You.

i think he is talking about foreach($array['DigitalAssets'] as $value) { $indexes += count($value); }

Eshban Bahadur Over a year ago

@Milan Rilex Ristic: When I echo $indexes it gives empty result. I just want to echo the count of total indexes in an array.

Milan Rilex Ristic Over a year ago

define it first like $indexes=array(); in parent scope

Eshban Bahadur Over a year ago

@Milan Rilex Ristic: with your code in first comment, I receive result 4025 because array has total 804 indexes. And each index has 5 values as I mentioned in my code. I need result 804 to be displayed instead of 4025

ThePueblo Over a year ago

Please try with seccond option set to 0 in count function use, from php manual:

If the optional mode parameter is set to COUNT_RECURSIVE (or 1), count() will recursively count the array. This is particularly useful for counting all the elements of a multidimensional array.
