Smarty:wordwrap
wordwrap
限制一行字符的长度（自动换行），默认是80个字符长度。 可选的第二个参数，可自定义换行字符，默认换行字符是 "\n"。 默认情况下，是根据单词来换行的，也就是按英文语法的自动换行。 如果你希望按照字符来换行（边界的单词将拆开），那么可以设置 可选的第三个参数为TRUE，效果与PHP函数wordwrap()一样。
| 参数顺序 | 类型 | 必选参数 | 默认值 | 说明 |
|---|---|---|---|---|
| 1 | integer | No | 80 | 限定一行的长度。 |
| 2 | string | No | \n | 换行符号 |
| 3 | boolean | No | FALSE | 设置按单词换行(FALSE)，或者按字符换行(TRUE)。 |
