The principle is that you can pass an array when submitting a web form. For example:

<input type="text" name="firstname">
<input type="text" name="lastname">
<input type="text" name="email">
<input type="text" name="address">
<input type="text" name="tree[tree1][fruit]">
<input type="text" name="tree[tree1][height]">
<input type="text" name="tree[tree2][fruit]">
<input type="text" name="tree[tree2][height]">
<input type="text" name="tree[tree3][fruit]">
<input type="text" name="tree[tree3][height]">

Copy after login

Then what is passed is:

$_POST[] = array(
  &#39;firstname&#39;=>&#39;value&#39;,
  &#39;lastname&#39;=>&#39;value&#39;,
  &#39;email&#39;=>&#39;value&#39;,
  &#39;address&#39;=>&#39;value&#39;,
  &#39;tree&#39; => array(
    &#39;tree1&#39;=>array(
      &#39;fruit&#39;=>&#39;value&#39;,
      &#39;height&#39;=>&#39;value&#39;
    ),
    &#39;tree2&#39;=>array(
      &#39;fruit&#39;=>&#39;value&#39;,
      &#39;height&#39;=>&#39;value&#39;
    ),
    &#39;tree3&#39;=>array(
      &#39;fruit&#39;=>&#39;value&#39;,
      &#39;height&#39;=>&#39;value&#39;
