Steam API decode URL json

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

Are the snippets of code above from `MarketPrices.php` and do they show the offending lines? — Professor Abronsius, Feb 16 '16 at 10:06
@DanielElmnas: The decoded value of `</br>` is ``. That means the value has a single line break. Try the PHP's `strip_tags()` first. — CAPS LOCK, Feb 16 '16 at 10:56
Could you explain more in detail I am a newbie to PHP. Could you provide me with a snippet? Thank you in advance — XsiSecOfficial, Feb 16 '16 at 12:02
@DanielElmnas: also, you have a `&` in the URL that you should replace. And delete the answer you posted as it is not an answer. You should update your question instead. — CAPS LOCK, Feb 16 '16 at 12:34
So the following result of the URL, should look like the example below: http://steamcommunity.com/market/priceoverview/?appid=570/market_hash_name=AWP%20|%20Worm%20God%20(Factory%20New) If I paste that in the browser I still get null thank you in advance — XsiSecOfficial, Feb 16 '16 at 12:37
@DanielElmnas: change `570/market_hash_name` to `570&market_hash_name`. It gets you some json. I am not familiar with how steam API works, though. — CAPS LOCK, Feb 16 '16 at 12:44

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.

How do other people solve to create an array from the pricelist? Thank you in advance – XsiSecOfficial Feb 22 '16 at 07:36
@DanielElmnas one way would be to send requests under x amount per minute, I believe it may have been something like 20 requests/minute. – ncla Feb 22 '16 at 13:06
If I should send x requests per min how should you make it then? Could you help me with an example if it is not to hard. by using the method I am using. Is this the easiest way to make this? Thank you in advance – XsiSecOfficial Feb 22 '16 at 13:28
Just noticed that you are sending incorrect appID for the CS:GO items, 570 is for Dota 2, 730 is for CS:GO. – ncla Mar 07 '16 at 18:10
