wordwrap

Parameter PositionTypeRequiredDefaultDescription
1integerNo80This determines how many columns to wrap to.
2stringNo\nThis is the string used to wrap words with.
3booleanNofalseThis determines whether or not to wrap at a word boundary (false), or at the exact character (true).

This wraps a string to a column width, default is 80. As an optional second parameter, you can specify a string of text to wrap the text to the next line (default is carriage return \n). By default, wordwrap will attempt to wrap at a word boundary. If you want to cut off at the exact character length, pass the optional third parameter of true.

此函式會根據欄位的寬度重新包裝字串，預設寬度是80。我們可以使用第二個參數， 指定將字串包裝到新的一行時所使用的字串（預設字串是 \n）。預設狀況下函式會根據單字作 包裝而不是字元，如果你希望在確定字元長度下作包裝的話，請使用第三個參數並將其設定為 true。
