CFormatter provides a set of commonly used data formatting methods.

The formatting methods provided by CFormatter are all named in the form of formatXyz. The behavior of some of them may be configured via the properties of CFormatter. For example, by configuring dateFormat, one may control how formatDate formats the value into a date string.

For convenience, CFormatter also implements the mechanism of calling formatting methods with their shortcuts (called types). In particular, if a formatting method is named formatXyz, then its shortcut method is xyz (case-insensitive). For example, calling $formatter->date($value) is equivalent to calling $formatter->formatDate($value).

Currently, the following types are recognizable:

raw: the attribute value will not be changed at all.
text: the attribute value will be HTML-encoded when rendering.
ntext: the formatNtext method will be called to format the attribute value as a HTML-encoded plain text with newlines converted as the HTML <br /> tags.
html: the attribute value will be purified and then returned.
date: the formatDate method will be called to format the attribute value as a date.
time: the formatTime method will be called to format the attribute value as a time.
datetime: the formatDatetime method will be called to format the attribute value as a date with time.
boolean: the formatBoolean method will be called to format the attribute value as a boolean display.
number: the formatNumber method will be called to format the attribute value as a number display.
email: the formatEmail method will be called to format the attribute value as a mailto link.
image: the formatImage method will be called to format the attribute value as an image tag where the attribute value is the image URL.
url: the formatUrl method will be called to format the attribute value as a hyperlink where the attribute value is the URL.

By default, CApplication registers CFormatter as an application component whose ID is 'format'. Therefore, one may call Yii::app()->format->boolean(1).
