Source code samples

Insert the sample source code between the three apostrophes:

```
function helloWorld() {
  alert('Hello, World!');
}
```

result:

function helloWorld() {
  alert('Hello, World!');
}

Or indent the whole sample by 4 spaces from the left:

    function helloWorld() {
      alert('Hello, World!');
    }

the result is the same:

function helloWorld() {
  alert('Hello, World!');
}

Syntax highlighting

After the opening triplet of apostrophes, you can write the programming language in which the sample is written.

Javascript sample with syntax highlighting:

```javascript
function helloWorld() {
  alert('Hello, World!');
}
```

function helloWorld() {
  alert('Hello, World!');
}

PHP block with syntax highlighting:

```php
$article = Article::FindById(1);
echo $article->getTitle();
var_dump($article->toArray());
```

$article = Article::FindById(1);
echo $article->getTitle();
var_dump($article->toArray());

The library GeSHi - Generic Syntax Highlighter is used for syntax highlighting. GeSHi contains rules for highlighting a large number of languages. Worth mentioning:

• php
• javascript
• html
• sql
• xml
• python
• ruby
