title: Insert a PHP variable inside Curl
body: <p>I have that Curl command works fine</p>
  
  <pre><code>$ch = curl_init('http://api.pushingbox.com/pushingbox?devid=vB9C6311111098CB&amp;sensor=DELTA&amp;temperature=23');
  curl_exec ($ch);
  
  curl_close ($ch);
  </code></pre>
  
  <p>But I need change de fix values DELTA and 23 to follow php variables</p>
  
  <p>$sensor
  $temperature</p>
  
  <p>My question is: How insert the variables $sensor and $temperature inside Curl command?</p>
