Question

I have a problem converting variables into array.
I am running foreach loop to get values from my multidimensional array $images. $images array contains image name eg: “Item Blue.png” or “Item Light Oak.png” and id of each image.

foreach ($images['images'] as $image) {
    $image_name = explode(" ", substr_replace($image->filename ,"",-4));
    if(!empty($image_name[2])) {
        $colour = ucfirst($image_name[1] . " " . $image_name[2]);
    }
    else {
        $colour = ucfirst($image_name[1]);
    }
}

$colour variable is giving me Color name and $image->id can give me image id.

I would like to build $colors array with above variables that it would look like this:

$colors = array(
    'Blue' => 1620,
    'Green' => 1467,
);

Kind of like this:

$colors = array(
    '$colour' => $image->id,
);

I have no idea how to do this and I will appreciate any help to give me at least some directions.

Thanks

This should be pretty straightforward … Two things to do:

First initialize the colors array outside of your foreach:

 $colors=array();   //<-- add this
 foreach ($images['images'] as $image) {
     $image_name = explode(" ", substr_replace($image->filename ,"",-4));
     ...

then just add one line after the if/else, still inside your foreach loop that will insert a new item into the $colors array.

    ...
    else {
        $colour = ucfirst($image_name[1]);
    }
    $colors[$colour]=$image->id;  //<-- add this
}

This will create a colors array with contents like what you’re looking for. I’m assuming that there is an ‘id’ key in the $image iterator. Did you need to create one?

All that said, you’re not checking for these problems:

1. color names with spaces, like ‘light oak’
2. item names with spaces like ‘large item light oak.png’
3. duplicate colors with different IDs

Hope that helps
