Get part of a website

Question

Good what I intended to do is to get the part of a site with php and store in a variable $price.

Well the link is as follows: http://steamcommunity.com/market/priceoverview/? currency=1&appid=730&market_hash_name=M249%20|%20Contrast%20Spray%20(Field-Tested)

From this link I wanted to get the value of "median_price":"$0.03" and store in that such variable of $price.

How can I do it?

Thank you.

Answer 1

It is possible with the following code:

<?php

  $url = "http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name=M249%20|%20Contrast%20Spray%20(Field-Tested)";  
  $json = file_get_contents($url);  
  $decode = json_decode($json, TRUE);   

  $preco_medio = $decode['median_price'];
?>

That is, we access the URL with file_get_contents and decoded the JSON, which will become a array. Therefore, we assign the value of array corresponding to the average price at the variable you want :)

PS: Through print_r it is possible to view the array generated from JSON to get the correct value to use in the brackets

print_r ($decode);
