Answer 1

Maybe I'm not getting the question but is this the expected result?

function title_resize($text, $max_length = 15, $fulltext = false)
{
    if ($fulltext)
    {
        return $text;
    }
    else 
    {
        return substr($text, 0, $max_length) . '...';   
    }
}

$str = "this item is for sale";

var_dump(title_resize($str, 10));

Answer 2

function title_resize($title, $length){
    return substr($title, 0, $length) . '...';
}

Answer 3

Try this.... It will show only dots when text greater than specified length.

<?php
function title_resize($text, $length = ''){
    $length = (empty($length)) ? 15 :    $length;
    $New_title  =   substr($text, 0, $length);
    if(strlen($text) > $length)
    {
        $New_title  .= "...";
    }
    return $New_title;
}
echo title_resize("this will only show fifteen characters");
?>

Thanks friends I did something like this one : it works but I am afraid if I loose something in original cod ?

 function title_resize($text, $max_length = 15, $fulltext = false)
{
    global $db;
    (string) $display_output = null;
     $text = $db->add_special_chars($text);
     if ($fulltext)
    {
    $output = $text;        
    }
    else 
    {
        $output = (strlen($text) > $max_length) ? substr($text, 0, $max_length) . '... '  : $text;

    }
    return $output;
}
