Question

My hosting provider has moved my PHP site over to a new server and believe the PHP version is current 7.x, however my site is v 5.6. I have no idea how to fix this.

I am receiving this error:

A PHP Error was encountered

Severity: Warning

Message: Illegal string offset 'posts'

Filename: controllers/Blog.php

Line Number: 13

Here is the code 'posts'

function __construct()
{
    parent::__construct();

    $this->data = '';
    $this->load->model('blog_model');
    $this->data['posts'] =  this->blog_model->get_all_blogs_and_posts('3');
}

If anyone has any suggestions would greatly appreciate the guidance...

What I have tried:

Not sure where to start, tried data['posts']= [];
but didn't work....

Quote:
The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array.

You have declared $this->data = ''; which is a string, not an array.
