Best way to output PHP array into csv file

I am currently working on a simple task yet a bit tricky. My task is to read all the images from the directory and write them into CSV file. So, when I read the directory I get the array list of images filename data will look like below:

array (

I wanted this data to be exported into csv file which looks like below:

So, I am going through the foreach loop as $image which gives me each element and each loop I am checking the string has ‘-’ character or not. If it has no ‘-’ character than I assign $currentId = $image but if it has ‘-’ then I assign $additionalImage .= ‘, ‘.$image.’.jpg’. But the problem is I only want to insert one row if it has additional images ‘13763.jpg, 13763-1.jpg, 13763-2.jpg’. Below is my code what I have done so far.

$currentId = '';
$additionalImages = '';
$addId = '';

foreach ($images as $image) {
    if (strpos($image, '-') == FALSE) {
        $currentId = $image;
        $additionalImages = $image.'.jpg';

    if (strpos($image, '-') != FALSE) {
        $addId = substr($image, 0, strpos($image, '-'));
        $additionalImages .= ', '.$image.'.jpg';

    // insert into csv file


Take a look at the fputcsv() function in PHP.

Sorry @SamA74 but this is not the issue I currently have. The issue is I could not able to generate single row from the array which I mentioned already.

I don’t understand the problem. It would be easier to follow if the spreadsheet you showed actually corresponded to the data in your array.
