PHP: How to extract() values from an associative array with hyphens/dashes in their keys?

Question

I'm referring to this question. Is it possible to extract() values from an associative array with hyphens/dashes in their keys by now?

It's about an older version of the WordPress Shortcode API. Example:

function bartag_func( $atts ) {
    extract( shortcode_atts( array(
        'foo-bar' => 'something'
    ), $atts ) );

    return "foo = ${foo-bar}";
}
add_shortcode( 'bartag', 'bartag_func' );

*`smacks forehead`* PHP still hasn't changed the rules on variable naming. If you need the values and you don't need them in variables you can use some other array parsing method. — Jay Blanchard, Jun 23 '16 at 19:20

It is still not possible. However, for the PHP.net engine, I have an RFC under discussion that would make it possible in PHP 8.

shortcode_atts returns an array so just use it.

function bartag_func( $atts ) {
    $params = shortcode_atts( array(
        'foo-bar' => 'something'
    ), $atts ) );

    return "foo = " . $params['foo-bar'];
}
add_shortcode( 'bartag', 'bartag_func' );

Good answer but it lacks a precise answer to the problem with exporting the field. – Julie Pelletier Jun 23 '16 at 19:24
