New line to paragraph function

Question

I have this interesting function that I\'m using to create new lines into paragraphs. I\'m using it instead of the nl2br() function, as it outputs better formatted

Answer 1

Here is another approach that doesn't use regular expressions. Note, this function will remove any single line-breaks.

function nl2p($string)
{
    $paragraphs = '';

    foreach (explode("\n", $string) as $line) {
        if (trim($line)) {
            $paragraphs .= '<p>' . $line . '</p>';
        }
    }

    return $paragraphs;
}

If you only need to do this once in your app and don't want to create a function, it can easily be done inline:

<?php foreach (explode("\n", $string) as $line): ?>
    <?php if (trim($line)): ?>
        <p><?=$line?></p>
    <?php endif ?>
<?php endforeach ?>
