Question

I’ve found a few tutorials on adding substr() to variables but not to functions. The output in html so far is:

<div class="symbol"><?php the_title();?></h3> 

Inside the_title() when I hover over it the following function in Eclipse it displays:

function = the_title($before = '', $after = '', $echo = true){
    $title = get_the_title();

    if (strlen($title) == 0 )
        return
    $title = $before . $title . $after

    if ($echo)
        echo $title;

    else
        ...

I’m just unsure whether I need to add to the function in the backend pages or I can code it in the front end.

You can use the function get_the_title() in wordpress to get the current title returned as a string:

$title = get_the_title();
$title_substr = substr($title, -1);

You don’t have to store the title in a variable, you can just go straight to:

$substr = substr(get_the_title(), -1);
