mb_strimwidth — Get truncated string with specified width

### Description

mb_strimwidth(
string `$string`,
int `$start`,
int `$width`,
string `$trim_marker` = "",
?string `$encoding` = `null`
): string

Truncates string `string` to specified `width`, where halfwidth characters count as `1`, and fullwidth characters count as `2`. See » http://www.unicode.org/reports/tr11/ for details regarding East Asian character widths.

### Parameters

`string`

  The string being decoded.

`start`

  The start position offset. Number of characters from the beginning of string (first character is 0), or if start is negative, number of characters from the end of the string.

`width`

  The width of the desired trim. If negative width is specified, count from the end of the string.

  > Note:

  > Passing negative width is deprecated as of PHP 8.3.0.

`trim_marker`

  A string that is added to the end of string when string is truncated.

`encoding`

  The `encoding` parameter is the character encoding. If it is omitted or `null`, the internal character encoding value will be used.

### Return Values

The truncated string. If `trim_marker` is set, `trim_marker` replaces the last chars to match the `width`.
