Invalid argument supplied for foreach()
Fix for
Warning: Invalid argument supplied for foreach() in /var/www/html/pages/seo-meta-tag-search.page.php on line 204
As this is just a warning, i may not have noticed it originally, but as i have all warnings and errors shown now, it is appearing, probably trying to loop through something that is not declared or blank.

Fixed: This was due to looping through an array that was not set.
PHP - Original Code
foreach($kw_latest_json_array as $kw_item) {
$kw_item_title = $kw_item['title'];
$kw_page_url = $kw_item['page_url'];
$kw_page_url_enc = urlencode($kw_page_url);
$kw_group .= "<a href='?import_url=$kw_page_url_enc' class='list-group-item list-group-item-action' title='$kw_item_title'>$kw_item_title</a>";
}
PHP - Check that the array isset
check if its an array, you could probably use isset here as well
if(is_array($kw_latest_json_array)) {
foreach($kw_latest_json_array as $kw_item) {
$kw_item_title = $kw_item['title'];
$kw_page_url = $kw_item['page_url'];
$kw_page_url_enc = urlencode($kw_page_url);
$kw_group .= "<a href='?import_url=$kw_page_url_enc' class='list-group-item list-group-item-action' title='$kw_item_title'>$kw_item_title</a>";
}

"Olivia, my eldest daughter, caught measles when she was seven years old. As the illness took its usual course I can remember reading to her often in bed and not feeling particularly alarmed about it. Then one morning, when she was well on the road to recovery, I was sitting on her bed showing her how to fashion little animals out of coloured pipe-cleaners, and when it came to her turn to make one herself, I noticed that her fingers and her mind were not working together and she couldn’t do anything. 'Are you feeling all right?' I asked her. 'I feel all sleepy,' she said. In an hour, she was unconscious. In twelve hours she was dead. The measles had turned into a terrible thing called measles encephalitis and there was nothing the doctors could do to save her. That was...in 1962, but even now, if a child with measles happens to develop the same deadly reaction from measles as Olivia did, there would still be nothing the doctors could do to help her. On the other hand, there is today something that parents can do to make sure that this sort of tragedy does not happen to a child of theirs. They can insist that their child is immunised against measles. ...I dedicated two of my books to Olivia, the first was ‘James and the Giant Peach’. That was when she was still alive. The second was ‘The BFG’, dedicated to her memory after she had died from measles. You will see her name at the beginning of each of these books. And I know how happy she would be if only she could know that her death had helped to save a good deal of illness and death among other children."
I just checked google books for BFG, and the dedication is there.
