Question

Say I am taking the following information from a textarea:

Coding is cool

Programming is coding

Green screens

I can print it out with bl2br, however what I want it to look like when it’s printed out is this:

<div class="coding">Coding is cool</div><div class="green"><?php //php query doing the same, but for another textbox ?></div><div class="one-more-class"></div>
<div class="coding">Programming is coding</div><?php //php query doing the same, but for another textbox ?></div><div class="one-more-class"></div>
<div class="coding">Green screens</div><?php //php query doing the same, but for another textbox ?></div><div class="one-more-class"></div>

The input has to be from textarea, not from separate textboxes. I’m not going into even more complex jQuery implementation. And speaking of which, no Javascript for this one – I believe it can be done with PHP.

First of all get the array of entries:

$ar = explode("\n", $_POST['textarea']);

then do whatever you want

echo implode("\n", arrray_map(function($str){
    //query
    return '<div class="coding">'.$str.'</div><div class="green">'.$queryres.'</div><div class="one-more-class"></div>';
}, $ar));

Need 5.3 for anonymous functions, you may use not anonimous ones instead.
