Zend Framework Truncate View Helper

This simple view helper for the Zend Framework will truncate a string to the desired length and automatically add customizable postfixes if the string was truncated.

Usage Example

This view helper is based on “normal” PHP

<?php echo $this->truncate($text, $length, array('ending'=>'..', 'exact'=>false)) ?>

After truncated string will look like this

<p>This is my long string which needs to be truncated..</p>

Due to the fact that this helper works on the string directly, you may need to strip html tags first if your string is HTML, otherwise you will end up with a lot of broken tags!

<?php
class My_View_Helper_Text_Truncate extends Zend_View_Helper_Abstract
{
    public function truncate($text, $length = 100, $options = array())
    {
        $default = array(
            'ending' => '...', 'exact' => false
        );
        $options = array_merge($default, $options);
        extract($options);

        if (mb_strlen($text) <= $length) {
            return $text;
        } else {
            $truncate = mb_substr($text, 0, $length - mb_strlen($ending));
        }

        if (!$exact) {
            $spacepos = mb_strrpos($truncate, ' ');
            if (isset($spacepos)) {
                $truncate = mb_substr($truncate, 0, $spacepos);
            }
        }
        $truncate .= $ending;
        return $truncate;
    }
}
