Question

The following function is part of code written into the core of a plugin I am reverse engineering. The problem with it is that I need to do an str_replace on it and I cannot because it is already set to echo.

The function is.

function similar_posts($args = '') {
    echo SimilarPosts::execute($args);
}

I call it in my pages using similar_posts(), but what I really need to do in my theme is call $related = similar_posts(), however that function is set to echo. How do I change that.

I tried this.

 function get_similar_posts($args = '') {
        SimilarPosts::execute($args);
    }

But that did not produce any results.

Answer 1

Use return instead of echo.

So that you have:

 return SimilarPosts::execute($args);

instead of:

 echo SimilarPosts::execute($args);
