- <p>Formats text so that it is semantically and typographically correct HTML.
- Takes a string as input and returns it with the following formatting:</p>
- <blockquote>
- <div><ul class="simple">
- <li>Surrounds paragraphs within <p></p> (looks for double line breaks to identify paragraphs).</li>
- <li>Single line breaks are converted to <br />, except those that appear within <pre> tags.</li>
- <li>Block level elements, like <div> tags, are not wrapped within paragraphs, but their contained text is if it contains paragraphs.</li>
- <li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li>
- <li>Apostrophes are converted to curly apostrophe entities.</li>
- <li>Double dashes (either like – this or like–this) are converted to em—dashes.</li>
- <li>Three consecutive periods either preceding or following a word are converted to ellipsis (…).</li>
- <li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li>
- </ul>
- </div></blockquote>
- <p>Usage example:</p>
- <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$string</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-></span><span class="na">typography</span><span class="o">-></span><span class="na">auto_typography</span><span class="p">(</span><span class="nv">$string</span><span class="p">);</span>
- </pre></div>
- </div>
- <p>There is one optional parameter that determines whether the parser should reduce more than two consecutive line breaks down to two.
- Pass boolean TRUE to enable reducing line breaks:</p>
- <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$string</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-></span><span class="na">typography</span><span class="o">-></span><span class="na">auto_typography</span><span class="p">(</span><span class="nv">$string</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>

- <p>This method is similar to <code class="docutils literal"><span class="pre">auto_typography()</span></code> above, except that it only does character conversion:</p>

- <li>Apostrophes are converted to curly apostrophe entities.</li>

- <p>Converts newlines to <br /> tags unless they appear within <pre> tags.
- This method is identical to the native PHP <code class="xref php php-func docutils literal"><span class="pre">nl2br()</span></code> function, except that it ignores <pre> tags.</p>
