 <h1><a name="caching">&nbsp;</a>Active Record Caching</h1>
 <p>While not &quot;true&quot; caching, Active Record enables you to save (or &quot;cache&quot;) certain parts of your queries for reuse later. Normally, when an Active Record call is completed, all stored information is reset for the next call. With caching, you can prevent this reset, and reuse information easily.</p>
-<p>Cached calls are cumulative.  If you make 2 cached select() calls, and then 2 uncached select() calls, this will result in 4 select() calls. There are three Caching functions available:</p>

 <p>is_writable() returns TRUE on Windows servers when you really can't write to the file as the OS reports to PHP as FALSE only if the read-only attribute is marked. This function determines if a file is actually writable by attempting to write to it first. Generally only recommended on platforms where this information may be unreliable.</p>
