title: how does codeigniter sanitize inputs?
body: <p>I'm building a Codeigniter application and I'm trying my hardest to prevent SQL injections. I'm using the Active Record method to construct all my queries.  I know Active Record automatically sanitizes the input, but I'm wondering exactly to what extent? Does it simply escape all the quotes, or does it do more?  What about preventing obfuscated SQL injections, or other more advanced kinds?</p>
  
  <p>Basically, I'm looking for an in-depth explanation of how CI sanitizes data. Anyone know?</p>
