Modifier truncate

Modifier truncates a variable to a character length.

{$long_string|truncate:$length:$etc:$by_words:$middle}

• $length, required. Parameter determines how many characters to truncate to.
• $etc, by default .... This is a text string that replaces the truncated text.
• $by_word, by default FALSE. This determines whether or not to truncate at a word boundary with TRUE, or at the exact character with FALSE.
• $middle, by default FALSE. This determines whether the truncation happens at the end of the string with FALSE, or in the middle of the string with TRUE.

{var $str = "very very long string"}

{$str|truncate:10:" read more..."} output: very very read more...
{$str|truncate:5:" ... ":true:true} output: very ... string

Modifier do not use mbstring when works with UTF8.
