Test driven development - a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case. - https://en.wikipedia.org/wiki/Test-driven_development

Markdown Fenced code blocks - "A code fence is a sequence of at least three consecutive backtick characters (`) or tildes (~). (Tildes and backticks cannot be mixed.) A fenced code block begins with a code fence, preceded by up to three spaces of indentation. The line with the opening code fence may optionally contain some text following the code fence; this is trimmed of leading and trailing spaces or tabs and called the info string. ... Although this spec doesn’t mandate any particular treatment of the info string, the first word is typically used to specify the language of the code block."

```ruby
def foo(x)
 return 3
end
```

Writing to a Database with PHP

The following PHP method is implemented within a database access class:

function create_with_id($id, $name) {
  $born = time();
  $id = mysqli_real_escape_string($this->db, $id);
  $name = mysqli_real_escape_string($this->db, $name);
  $sql = "INSERT INTO object
      (object_id, display_name_text, born, died)
    VALUES
      ($id, '$name', $born, 0);
  ";
  db_run_sql($this->db, $sql);
}

Note db_run_sql is a helper function defined elsewhere, not a built in function, and the property db is a previously initialized mysqli object.
