Trim headline to nearest word

Question

Say for example I have the following code:

My very long title
Another long title

If I wanted to

Answer 1

This is easy using a PHP function. Look at this example:

function trim_text($input, $length) {

    // If the text is already shorter than the max length, then just return unedited text.
    if (strlen($input) <= $length) {
        return $input;
    }

    // Find the last space (between words we're assuming) after the max length.
    $last_space = strrpos(substr($input, 0, $length), ' ');
    // Trim
    $trimmed_text = substr($input, 0, $last_space);
    // Add ellipsis.
    $trimmed_text .= '...';

    return $trimmed_text;
}

You can then pass in text with a function like:

trim_text('My super long title', 10);

(I haven't tested this, but it should work perfectly.)
