Inserting content within HEREDOC using Functions

Question

Been trying to go bout how to accomplish dividing content on view output.

I'm loading records from Mysql, inserting values into HEREDOC to then output to view.

I want to display only a certain amount of characters in a particular row within the HEREDOC, hide the rest from view on DOM.

I tried using a function like this within the HEREDOC to insert a "More" link after certain amount of characters.

I've tried a couple methods:

1

<<<EOT
<div id="$id_op">
    {substr_replace($contents, "More", 400)}
</div>

EOT;

2

<<<EOT
    <div id="$id_op">
        {${substr_replace($contents, "More", 400)}}
    </div>

EOT;

There might be other better methods to accomplish this. For now I want to load the record completely into dom but hide part of it until user have clicked a jQuery selector.

Any help / direction will be truly appreciated.

Answer 1

Compute any variable content before starting the HEREDOC, then insert the variables into the string as you go.

Answer 2

Functions does not execute in HEREDOC. This will work

$div = substr_replace($contents, "More", 400);
$data = <<<EOT
<div id="$id_op">
    $div
</div>
EOT;
