从字符串开始处截取某长度的字符，默认是80个，你也可以指定第二个参数作为追加在截取字符串后面的文本串。该追加字串被计算在截取长度中。默认情况下,smarty会截取到一个词的末尾。如果你想要精确的截取多少个字符,把第三个参数改为"true" 。
| 参数位置 | 参数类型 | 是否必需 | 默认 | 描述 |
|---|
| 1 |

80 |

| 2 |

截取后追加在截取词后面的字符串 |
| 3 |
boolean |
No |
false |
是截取到词的边界（false）还是精确到字符（true） |
| 4 |
boolean |
No |
false |
设置为FALSE将截取至字符串末尾，设置为TRUE则截取到中间。注意如果设了TRUE，则忽略字符边界。 |
