PHP fetch strings from different function

Question

I have a function like this:

function colorscheme( $color, $url ) {
    return array( $color, $url );
}

How can I fetch them and display them like this (this is an example, it doesn't work):

function fetch_colorscheme() {
    foreach() {
         echo "<ul><li>$color</li><li>$url</li></ul>";
    }
}

Thank you!!

Your first function just returns a one-dimensional array, so just call the function and save the return value in a variable. Then you can access the array elements. — Rizier123

Honestly, your colorscheme() function is the most redundant thing I've ever seen. — BadHorsie

^Adding to what @Rizier123 said, here's a quick example, foreach(colorscheme('yourColor', 'yourURL') as $key => $value){ echo $key . ' => ' . $value . '<br />'; } — Rajdeep Paul

Try this:

$scheme = colorscheme('color', 'url');

echo '<ul>';
foreach ($scheme as $value) {
    echo '<li>' . $value . '</li>';
}
echo '</ul>';

Edit:

For multiple color schemes, you can do this:

$schemes = array(
    colorscheme('color 1', 'url 1'),
    colorscheme('color 2', 'url 2')
);
function fetch_colorscheme($schemes) {
    echo '<ul>';
    foreach ($schemes as $scheme) {
        foreach ($scheme as $value) {
            echo '<li>' . $value . '</li>';
        }
    }
    echo '</ul>';
}

I'm sorry, I'm not able to test this at the moment.

Try using sprintf or vsprintf when building markup text, eg: sprintf("<ul><li>%s</li><li>%s</li></ul>", $color, $url). It's more tidy IMHO.

That does it, but if someone adds multiple colorschemes, how would that work out?

And is it possible with just all function like in my example? thank you for your effort btw
