What are the best practices for customizing the display of additional smilies in a PHP forum?

When customizing the display of additional smilies in a PHP forum, it is important to first create a function that replaces the default smilies with your custom ones. This can be done by mapping the default smilies to your custom ones in an array. Then, you can use the str_replace function to replace the default smilies with your custom ones in the forum posts. 

function customize_smilies($content) {
    $smilies = array(
        ':)' => '<img src="custom_smile.png" alt=":)" />',
        ':(' => '<img src="custom_sad.png" alt=":(" />',
        ';)' => '<img src="custom_wink.png" alt=";)" />'
    );

    $content = str_replace(array_keys($smilies), array_values($smilies), $content);

    return $content;
}

// Example usage
$post_content = "Hello world! :) This is a test post.";
echo customize_smilies($post_content);
