Truncate string to given maximum length without breaking words
This method can truncate between words, sentences, punctuation or blocks (like paragraphs). See the type option for details on how it should truncate. By default it truncates between
words. Description of types:
- word: truncate to closest word.
- punctuation: truncate to closest punctuation within sentence.
- sentence: truncate to closest sentence.
- block: truncate to closest block of text (like a paragraph or headline).
Note that if your specified type is something other than “word”, and it cannot be matched within the maxLength, then it will attempt a different type. For instance, if you specify
“sentence” as the type, and it cannot match a sentence, it will try to match to “punctuation”
instead. If it cannot match that, then it will attempt “word”.
HTML will be stripped from returned string. If you want to keep some tags use the keepTags or keepFormatTags
options to specify what tags are allowed to remain. The keepFormatTags option that, when true, will make it
retain all HTML inline text formatting tags.
Example
// Truncate string to closest word within 150 characters
$s = $sanitizer->truncate($str, 150);
// Truncate string to closest sentence within 300 characters
$s = $sanitizer->truncate($str, 300, 'sentence');
// Truncate with options
$s = $sanitizer->truncate($str, [
'type' => 'punctuation',
'maxLength' => 300,
'visible' => true,
'more' => '…'
