array_map skip column

[jarvis]

Hi All,

I hope I've used the right/correct term for this.

So I'm using: 

array_map(addQuotes, $line)

Which calls this function:

function addQuotes($line) {
	return "\"$line\"";
}

It works and adds quotes around everything I need. However, I need to exclude one column called SKU.

Is it possible to use the above but skip this column? I know using array_map means you need to return the same number of columns, so my thought was:

	function addQuotes($line) {
		
		if( $line['SKU']){
			return $line;
		} else {
			return "\"$line\"";
		}
		
	}

Therefore not applying the quote treatment.

Sadly, didn't work (not surprised as figured it was too obvious!

The data is an array:

Array
(
    [0] => Array
        (
            [0] => SKU
            [1] => Name
            [2] => Product Category
            [3] => ImageURL
            [4] => Manufacturer
            [5] => Model
            [6] => MPN
            [7] => EAN
            [8] => MemberID
        )

    [1] => Array
        (
            [SKU] => CIHYG21SX
            [Name] => Beko CIHYG21SX 60cm Gas Hob - Stainless Steel
            [Product Category] => Gas Hobs
            [ImageURL] => https://www.domain.com/uploads/2021/Beko-CIHYG21SX.png
            [Manufacturer] => Beko
            [Model] => CIHYG21SX
            [MPN] => CIHYG21SX
            [EAN] => 8690842386756
            [MemberID] => 456789
        )

    [2] => Array
        (
            [SKU] => T26DS49N0
            [Name] => Neff T26DS49N0 60cm Gas Hob - Stainless Steel
            [Product Category] => Gas Hobs
            [ImageURL] => https://www.domain.com/uploads/2018/Neff-T26DS49N0.jpg
            [Manufacturer] => Neff
            [Model] => T26DS49N0
            [MPN] => T26DS49N0
            [EAN] => 4242004203384
            [MemberID] => 456789
        )

)

I'm then using a loop to get the data and pass into my function (if that helps)

No doubt something I've overlooked but any help is much appreciated!

This can be ignored. I found an alternative solution

Apologies!

array_map doesn't pass the array key. You could call it with two arrays (the first of values and second of keys) but that would reindex the array.

array_walk with the value by-reference would work. As would a simple foreach loop.
