Question

Take a look:

for ($i=1; $i<=$nr_of_pics; $i++) {
        ${'image_src' . $i} = $image_id.'_'.$i;
        $img_array = imageSize(${'image_src' . $i}, $i, $category);


    }

and here is the imageSize function (simplified):

$myarr = array();
    $myarr['thumb_image_' . $nr . '_width'] = $thumb_width;
    $myarr['thumb_image_' . $nr . '_height'] = $thumb_height;
    $myarr['image_' . $nr . '_width'] = $width;
    $myarr['image_' . $nr . '_height'] = $height;
    return $myarr;

The function gets called and OWERWRITES the value of the $img_array inside the foor-loop, but I need it to ‘increment’ and add values after another in every loop.
So basically, it replaces its value every time it loops.
What should I do here?

Thanks

Answer 1

You’re overwriting $img_array each time through the loop. Try changing

$img_array = imageSize(${'image_src' . $i}, $i, $category);

to

$img_array[] = imageSize(${'image_src' . $i}, $i, $category);

This will add an element to $img_array instead of replacing its value.
