truncate
truncate(string $text, int $length=100, array $options)
Cuts a string to the $length and adds a suffix with ‘ending’ if the text is longer than $length. If ‘exact’ is passed as false, the truncation will occur after the next word ending. If ‘html’ is passed as true, html tags will be respected and will not be cut off.
Text->truncate方法有3个参数:
$text：需要截取的字符串
$length：需要截取的长度，默认是截取100个字符
$options：数组参数。ending表示在截取后的字符串结尾加上ending字符串；exact如果是false的话则不会截断word；html如果是true的话则不会截断html tag
下面的代码演示了如何使用tuncate方法：

echo $this->Text->truncate(
'The killer crept forward and tripped on the rug.',
22,
array(
'ending' => '...',
'exact' => false
)
);
echo $this->Text->truncate( 'The killer crept forward and tripped on the rug.', 22, array( 'ending' => '...', 'exact' => false ));
