title: unserialize() php function not converting when I put folder address instead URL
body: <p>I am inserting post meta into database using wordpress, the field I want to insert is video url but sometimes I insert video folder address from my windows.
  the way they are inserted is like this:</p>
  <pre><code>s:162:&quot;a:1:
      {i:0;a:5:
          {s:4:&quot;type&quot;;
          s:1:&quot;2&quot;;s:4:&quot;lang&quot;;
          s:3:&quot;364&quot;;s:7:&quot;quality&quot;;
          s:3:&quot;365&quot;;
          s:4:&quot;link&quot;;
          s:41:&quot;https://www.youtube.com/embed/j49fPpRiNgc&quot;;
          s:4:&quot;date&quot;;
          s:4:&quot;2021&quot;;}}&quot;;
  s:306:
      &quot;a:2:{i:0;a:5:
          {s:4:&quot;type&quot;;
          s:1:&quot;2&quot;;
          s:4:&quot;lang&quot;;
          s:3:&quot;364&quot;;
          s:7:&quot;quality&quot;;
          s:3:&quot;366&quot;;
          s:4:&quot;link&quot;;
          s:27:&quot;D:\films\242\Pompeii.mkv&quot;;
          s:4:&quot;date&quot;;s:9:&quot;30/6/2021&quot;;}}&quot;;
  </code></pre>
  <p>The first one is video URL and the second one is video address. So when I want to show them first I need to convert to array using unserialize() function but for video address, its not working.</p>
  <pre><code>&lt;?php
      $trmovieslinks = unserialize(get_post_meta($post-&gt;ID, 'trmovieslink', true)); 
      var_dump($trmovieslinks);   
  ?&gt;
  </code></pre>
  <p>for video address it returns nothing.</p>
