<?php
public function get_posts_for_category($user_id,$category_id,$page)
{
$cat_id = $this->ApiModel->get_category_id($category_id);
$total_row = $this->ApiModel->get_category_posts_count($cat_id->category);
$per_page = 2;
$total_pages = $total_row / $per_page;
$posts = $this->ApiModel->get_category_posts($cat_id->category,$per_page,$page);
$data = array();
foreach($posts as $post)
{
$fav = $this->ApiModel->get_favourite($user_id,$post->pid);
if($fav == 1)
{
$status = 'true';
}
else
{
$status = 'false';
}
$array = array('pid' => $post->pid, 'uid' => $post->uid, 'title' => $post->title, 'slug' => $post->slug, 'content' => $post->content, 'image' => $post->image, 'time_stamp' => $post->time_stamp, 'is_favorite' => $status);
$data[] = array('page' => $page, 'posts' => $array, 'total_posts' => count($posts), 'total_pages' => $total_pages);
}
echo strip_tags(json_encode($data));
}
?>

$return = array(
'page' => $page,
'total_posts' => $total_row,
'total_page' => $total_pages,
);
$data = [];
foreach($posts as $post)
{
$fav = $this->ApiModel->get_favourite($user_id, $post->pid);
if($fav == 1)
{
$status = 'true';
}
else
{
$status = 'false';
}
$array = array('pid' => $post->pid, 'uid' => $post->uid, 'title' => $post->title, 'slug' => $post->slug, 'content' => $post->content, 'image' => $post->image, 'time_stamp' => $post->time_stamp, 'is_favorite' => $status);
$data[] = $array;
}
$return['posts'] = $data;
$this->output->set_content_type('application/json');
$this->output->set_output(json_encode($return));
just replace this code with your foreach & echo statement.
You never should use strip_tags in conjunction with json_encode because you are already encoding the data it's receivers choice to do whatever he wants also in this process you might break the encoding.
Also you should use CI output library to send response you must not echo anything from your controller. see here https://ellislab.com/codeigniter/user-guide/libraries/output.html for more details

If you would like the numeric values to be output as such, (instead of strings) you may wish to try:
json_encode($return, JSON_NUMERIC_CHECK);
To format the outputted JSON nicely (indentation etc) use:
json_encode($return, JSON_PRETTY_PRINT);
You can use various combinations of the above as per json_encode's options.
As for the boolean values (instead of "true" and "false" returned as strings), you'll need to cast them as boolean types first:
$status = (bool) true;
