Steam API decode URL json - php

Question

I am trying to make a "echo" prices for different objects I have got in an array that contains weapons:
I have read lots about how to get prices through through Steammarket through Steamapi:
(none of these sources did fit my requirements)
Sources:
Get steam item prices
How get a response of multiple price items on the market
Get the price of an item on Steam Community Market with PHP and Regex
I found finally a code snippet that works flawless
FILE marketprices.php
<?php
$items = array("Exalted Manifold Paradox","Kinetic Gem","Mercurial's Call");
foreach($items as $item)
{
$json = json_decode(file_get_contents("http://steamcommunity.com/market/priceoverview/?appid=570&market_hash_name=".rawurlencode($item)), true);
if($json["success"] == true OR !empty($json))
{
echo $item."'s lowest price is ".$json["lowest_price"]."";
}
elseif($json["success"] == false OR empty($json))
{
echo "Could not get data for ".$item;
}
}
output>
Exalted Manifold Paradox's lowest price is $28.49Kinetic Gem's lowest price is $50.00Mercurial's Call's lowest price is $0.16

When I am trying to implent this snippet to my code I get error in my result:
I have created an array that contains different weapons:
<?
foreach($S_W as $item) // Steam weapon
{
echo $item;
}
?>
output>
AWP | Worm God (Factory New)
FAMAS | Cyanospatter (Field-Tested)
G3SG1 | Green Apple (Factory New)
G3SG1 | Polar Camo (Field-Tested)
Glock-18 | Death Rattle (Field-Tested)
M249 | Gator Mesh (Field-Tested)
MAC-10 | Heat (Field-Tested)
This is good so far..
I get error in the result
Here is my code below:
foreach($S_W as $item)
{
$json = json_decode(file_get_contents("http://steamcommunity.com/market/priceoverview/?appid=570&market_hash_name=".rawurlencode($item)), true);
if($json["success"] == true OR !empty($json))
{
echo $item."'s lowest price is ".$json["lowest_price"]."";
}
elseif($json["success"] == false OR empty($json))
{
echo "Could not get data for ".$item;
}
}
I receive following result:
I see a part of the error..
in the call in the end of the URL the code adds:</br>
Could someone help me with a solution?
Thank you in advance
Best regards

Priceoverview 'API' endpoint is rate-limited by Steam, and was even further rate-limited by Valve very recently. You are getting 429 HTTP Status code, which stands for 'Too many requests', you are sending requests to their site way too often.
