I’m trying to use word_wrap() function but the text is not wrapped.
I’ve used the example in the CI guide:

$string = "Here is a simple string of text that will help us demonstrate this function.";

echo word_wrap($string, 25);

// Would produce:

Here is a simple string
of text that will help
us demonstrate this
function

Can you explain that ??
Is it a potential candidate bug ??

Without testing it myself I am guessing you are trying to produce the text when viewing through a browser.

If you goto view the source of the page you will see it most likely is word wrapped - but browsers only render a new line with a <br /> or <br> tag. This function from memory is built more in use for something like an email message body.

So!!! We have no alternative of


wordwrap($text, 8, "\n", true);

I am very much hopeful, codeigniter will add this functionality very soon.

Sumon, you can absolutely use PHP in CodeIgniter. If you want to use PHP’s native wordwrap() function, go for it!

Yes that’s true and thanks for your kind feedback. but i shall be more happy if i get something like


word_limiter()

of CI. word_limiter() is an excellent function and if we get similar function for word_wrap that should be more pleasant. However, thanks.

No problem. Here you go. Add this to system/application/helpers/text_helper.php

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

function word_wrap($str, $width, $break = "\n", $cut = FALSE)
{
    return wordwrap($str, $width, $break, $cut);
}
