PHP Version?

It looks like this might require a more recent version of PHP. Is that correct?

I get this error when trying to activate:

Parse error: syntax error, unexpected ‘[‘ in /var/www/html/dev/clippermagazine/wp-content/plugins/tinywym-editor/tinywym-editor.php on line 92

The line is:

$disabled = isset( $settings[ 'disable' ] ) ? $settings[ 'disable' ] : [];
