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  
    )  
);

//上面的代码将输出The killer crept… 

注意:如果是截取中文字符串的话exact最好置为true,否则汉语字符将无法被截断.
