codeigniter ellipsis in php read more text

To add an ellipsis to a "Read More" text in CodeIgniter using PHP, you can follow these steps:

1. First, create a helper file in your CodeIgniter application. This file will contain a function that will add the ellipsis to the text.

2. Open your CodeIgniter application's "helpers" directory and create a new PHP file. You can name it something like "text_helper.php".

3. In the newly created file, define the function that will add the ellipsis. For example, you can name the function "add_ellipsis". The function should accept two parameters: the text string and the maximum number of characters you want to display.

4. Inside the function, check if the length of the text is greater than the maximum number of characters. If it is, use the PHP substr function to truncate the text to the desired length.

5. After truncating the text, append an ellipsis to the end using the concatenation operator ..

6. Finally, return the modified text from the function.

Here's an example implementation of the "add_ellipsis" function:

function add_ellipsis($text, $max_chars) {
    if (strlen($text) > $max_chars) {
        $text = substr($text, 0, $max_chars) . '...';
    }
    return $text;
}

To use this function in your CodeIgniter application, you need to load the helper file. You can do this in your controller or in the autoload configuration.

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

Once the helper is loaded, you can call the "add_ellipsis" function wherever you want to add the ellipsis to the text.

For example, if you have a variable called $content containing the text you want to add the ellipsis to, you can use the function like this:

$truncated_text = add_ellipsis($content, 100); // Replace 100 with the desired maximum number of characters

This will assign the truncated text with the ellipsis to the variable $truncated_text.
