I am fetching all details of product from database, and successfully get in view, but in between there is product details is too long so i want to split that text. I have also create a function of limit_text in main controller that is:

function limit_text($text, $length) // Limit Text
{
    if(strlen($text) > $length) {
        $stringCut = substr($text, 0, $length);
        $text = substr($stringCut, 0, strrpos($stringCut, ' '));
    }
    return $text;
}

but problem is that i unable to call this function from view....please help me..

    Instead of creating function in your controller, i suggest you create it in helper so that you can access it easily from view file. Create helper, say mysome_helper.php:

    <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
    
    function limit_text($text, $length) // Limit Text
    {
        if(strlen($text) > $length) {
            $stringCut = substr($text, 0, $length);
            $text = substr($stringCut, 0, strrpos($stringCut, ' '));
        }
        return $text;
    }
    

    and load it in your controller:

    $this->load->helper('mysome');
    

    and then you can access in view, like:

    <?php echo limit_text("some long tezxt", 120); ?>
