title: how to remove curly braces in php
body: <p>I am having one variable 
  $uuid={"uuid": "<strong>28fb72ed-0e97-4e78-9404-b676289b33ee</strong>"};</p>
  
  <p>which i am getting after execution </p>
  
  <p>i need to extract 28fb72ed-0e97-4e78-9404-b676289b33ee just the number </p>
  
  <p>how do you do it in php any ideas</p>
  
  <p>i am including some code here 
  i am using crcodoc viewer and i have generated the uuid using crocodoc api 
  now to check the status i need the uuid seperatly ... it is passing the whole variable 
  i have to split and get the uuid alone</p>
  
  <pre><code>    $ch = curl_init(); 
                  @curl_setopt($ch, CURLOPT_HEADER, 0);
                  @curl_setopt($ch, CURLOPT_HTTPHEADER,  array('Accept: application/json', 'X-HTTP-Method-Override: POST'));
                  @curl_setopt($ch, CURLOPT_POST, 1);
                  @curl_setopt($ch, CURLOPT_POSTFIELDS,$param);
                  @curl_setopt($ch, CURLOPT_URL, $frameUrl);   
                  @curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
                  @curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
                  curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
                  curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
                  $uuids = curl_exec($ch);
   echo $uuids;
   echo "\n\nchecking status of : ", $uuids;
  $status =getStatus($uuids,$api_url,$myToken);
  </code></pre>
  
  <p>probably regex or explode () or implode () function should be used here </p>
