Convert stdClass object to array in PHP

Convert stdClass object to array in PHP
The easiest way is to JSON-encode your object and then decode it back to an array:
$array = json_decode(json_encode($object), True);
Or if you prefer, you can traverse the object manually, too:
foreach ($object as $value)
    $array[] = $value->post_id;

Open and Close a ul after every 3rd li in php

<!DOCTYPE html>
<html lang=”en”>
<head>

</head>
<body>
<div class=”container”>
  <h2>Basic List Group</h2>
<?php
$products = array(1,2,3,4,5,6,7,8,9,10);
?>
<?php foreach ($products as $key => $prod) { ?>
<?php if( ($key+1)==1 || (($key+1)%3)==1 ) { ?>
<ul class=”list-group”>
<?php } ?>
<li class=”list-group-item”>First item</li>
<?php if( (($key+1)%3)==0 ){ ?>
</ul>
