Insert element into an array in PHP - php

Question

foreach($key_doc_count as $item) {
mb_language('Japanese');
$product = $item["key"];
$product_url = 'https://search.rakuten.co.jp/search/mall/'.urlencode($product) . '/';
$source = file_get_contents($product_url);
$source = mb_convert_encoding($source, 'utf8', 'auto');
$rakuten_search_html = str_get_html($source);
$count=0;
foreach ($rakuten_search_html->find('img._verticallyaligned') as $item_image) {
if(strlen($item_image->alt > 2))
{
$ss['image_url'] = $item_image->src;
$ss['title'] = $item_image->alt;
$items_kk[] = $ss;
$count++;
if($count <5)
{
break;
}
}
}
$new_item["term"] = $item["key"];
$new_item["current_count"] = $item["doc_count"];
$new_item["results"] = $terms_kk;
$new_word_array[] = $new_item;
}
var_dump($new_word_array);
I am trying to insert the url and title of the product in an array names $ss and then assign that array to $new_term["result"] .
But its not working
The error was HTTP ERROR 500

The variables $items_kk and $new_word_array seems to have not been initialized outside of the foreach loop. Try to init them as an empty array just before the loop :
$new_word_array = [];
foreach($key_doc_count as $item) {
mb_language('Japanese');
$product = $item["key"];
$product_url = 'https://search.rakuten.co.jp/search/mall/'.urlencode($product) . '/';
$source = file_get_contents($product_url);
$source = mb_convert_encoding($source, 'utf8', 'auto');
$rakuten_search_html = str_get_html($source);
$count=0;
$items_kk = [];
foreach ($rakuten_search_html->find('img._verticallyaligned') as $item_image) {
if(strlen($item_image->alt > 2))
{
$ss['image_url'] = $item_image->src;
$ss['title'] = $item_image->alt;
$items_kk[] = $ss;
$count++;
if($count <5)
{
break;
}
}
}
$new_item["term"] = $item["key"];
$new_item["current_count"] = $item["doc_count"];
$new_item["results"] = $terms_kk;
$new_word_array[] = $new_item;
}
var_dump($new_word_array);
Also, you're setting $items_kk and assigning $terms_kk to the new array. It may be an error ?
