wordwrap — Wraps a string to a given number of characters

### Description

wordwrap(
string `$string`,
int `$width` = 75,
string `$break` = "\n",
bool `$cut_long_words` = `false`
): string

Wraps a string to a given number of characters using a string break character. Strings wrap after a space (U+0020) character unless `cut_long_words` is set to `true`.

### Parameters

`string`

  The input string.

`width`

  The number of characters at which the string will be wrapped.

`break`

  The line is broken using the optional `break` parameter. It must not be an empty string.

`cut_long_words`

  If the `cut_long_words` is set to `true`, the string is always wrapped at or before the specified `width`. So if you have a word that is larger than the given width, it is broken apart. (See second example). When `false` the function does not split the word even if the `width` is smaller than the word width.

### Return Values

Returns the given string wrapped at the specified length.

### Errors/Exceptions

If `break` is an empty string, a ValueError is thrown.

### Changelog

Version | Description
--- | ---
8.0.0 | If `break` is empty string, a ValueError is thrown; previously in this case it emitted an `E_WARNING` and returned `false`.
