title: Make array from $_POST values
body: <p>Let's start telling that I'm passing an x amount of variables via post from a form.<br/>
  Let's name them <code>menu_category_1</code>, <code>menu_category_2</code>, ..., <code>menu_category_x</code>, plus, maybe, menu_category_new (I'm using an if empty to check this last one variable).</p>
  
  <p>To make things easier I'm also sending the parameter <code>$key</code> (amount of variables starting from 0).<br/>
  Now I need to set them into a new variable <code>$menu_category</code> (array), which is going to be imploded and then update my database. </p>
  
  <p>How do I set up that new <code>$menu_category</code> variable to be an array containing all my variables named in the beginning? <br/>
  I was thinking of using a for loop but I can't come up with something useful.
  Thanks!!!</p>

  <p>I ended up going the Quentin way, just adding [] to the keys. I chose this just because it worked right away. However I'm going to dig deeper on janenz00's sugestion, which I personally think is the way to go.
  Thanks to all of you who took the time to go through this!!!!</p>
