title: Trying to find and get rid of this \u0000 from my json
body: <p>This is my <code>$var</code> from <code>json_encode</code>:</p>
  
  <pre><code>{
  "key1":"\u0000data1",
  "key2":"\u0000data2",
  "key3":"\u0000data3",
  "key4":"\u0000data4
  }
  </code></pre>
  
  <p>I would like to do this:</p>
  
  <pre><code>echo json_encode(str_replace ("\\u0000", "",  $var));
  </code></pre>
  
  <p>in order to get rid of the preceding <code>\u0000</code> that's showing up, the line above doesn't work to strip it. </p>
