Question

i’m trying to build an array from an Object in PHP. I only want certain properties from the object but I don;t know what they will be each time. The names of the properties I need are stored in an array. Here is how my code works currently:

// Hard-coded attributes 'colour' and 'size'

while ($objVariants->next())
{   
    $arrVariants[] = array
    (   
        'pid' => $objVariants->pid,
        'size' => $objVariants->size,
        'colour' => $objVariants->colour,
        'price' => $objVariants->price                                                      
    );        
}

Instead of hard coding the attributes (colour and size) I want to use variables, this is because it may not always be colour and size depending on what the user has set in the CMS. For example:

$arrVariantAttr = $this->getVariantAttr(); // Get the names of the custom variants and put them in an array e.g colour, size

while ($objVariants->next())
{   
    $arrVariants[] = array
    (   
        'pid' => $objVariants->pid,

        foreach($arrVariantAttr as $attr)
        {
            $attr['name'] => $objVariants-> . $attr['name']; // Get each variant out of the object and put into an array
        }

        'price' => $objVariants->price                                                      
    );        
}

The above code doesn’t work, but hopefully it illustrates what i’m trying to do. Any help would be appreciated, thank you!

Try something like this:

$arrVariants[] = Array(
  'pid' => $objVariants->pid,
  'price' => $objVariants->price
);

while( $objVariants->next() )
{
  foreach( $arrVariantAttr as $attr )
  {
    end($arrVariants)[$attr['name']] = $objVariants->$attr['name'];
  }
}
