O Guia Definitivo do Yii 1.1

The CDateFormatter class mainly provides two methods to format a UNIX timestamp.
• format: this method formats the given UNIX timestamp into a string according to a
customized pattern (e.g. $dateFormatter->format('yyyy-MM-dd',$timestamp)).
• formatDateTime: this method formats the given UNIX timestamp into a string
according to a pattern predefined in the target locale data (e.g. short format of date,
long format of time).
Number Formatting
Like data and time, numbers may also be formatted differently in different countries or
regions. Number formatting includes decimal formatting, currency formatting and
percentage formatting. Yii providesCNumberFormatter for these tasks.
To get the number formatter associated with the target locale of the whole application, we
can access the numberFormatter property of the application.
The following methods are provided by CNumberFormatter to format an integer or double
value.
• format: this method formats the given number into a string according to a customized
pattern (e.g.$numberFormatter->format('#,##0.00',$number)).
• formatDecimal: this method formats the given number using the decimal pattern
predefined in the target locale data.
• formatCurrency: this method formats the given number and currency code using the
currency pattern predefined in the target locale data.
• formatPercentage: this method formats the given number using the percentage
pattern predefined in the target locale data.
Sintaxe Alternativa de Templates
Yii allows developers to use their own favorite template syntax (e.g. Prado, Smarty) to
write controller or widget views. This is achieved by writing and installing a viewRenderer
application component. The view renderer intercepts the invocations of
CBaseController::renderFile, compiles the view file with customized template syntax, and
renders the compiling results.
Info: It is recommended to use customized template syntax only when writing views
that are less likely to be reused. Otherwise, people who are reusing the views would be
forced to use the same customized template syntax in their applications.
In the following, we introduce how to use CPradoViewRenderer, a view renderer that
allows developers to use the template syntax similar to that in Prado framework. For
people who want to develop their own view renderers, CPradoViewRenderer is a good
reference.
Using CPradoViewRenderer
To use CPradoViewRenderer, we just need to configure the application as follows:
