foreach array values into a single string

Question

Im using PHP to output the category information from an RSS feed:

foreach(item_category()) as $category) { 
    $source = $category->cat_name; 
    echo $source.'.png';
}

Where item_category is an array of category names. I then have a set of corresponding images I've like to display against each item.

At the moment my output looks like this:

category1.pngcategory2.pngcategory3.png

but I need:

category1category2category3.png

How can I construct the correct file name with the single occurence of the file extension at the end of the string?

Here's an alternative solution that doesn't use a local variable

echo implode('', array_map(function($c){
    return $c->cat_name;
}, item_category()) . '.png';

(Requires PHP >= 5.3)

foreach(item_category()) as $category) { 
    $source .= $category->cat_name; 
}

echo $source'.png';

this should output

cat1cat2cat3.png

The quick answer is to put this line

echo $source.'.png';

Outside your foreach loop.
