<p>When you try to use preview pane in Windows Explorer to view .php files you might get the following message:</p>
<p><strong>No preview available</strong></p>
<p>This issue occurs when you don&#8217;t have installed any <span style="color: #003366;">.php</span> handler like <span style="color: #003366;">Adobe Dreamweaver</span> for instance.</p>
<p>To resolve this, we&#8217;ll need to do changes to Windows Registry.</p>
<p><!--more--></p>
<p>Hit <span style="color: #003366;">Win ORB</span> (Start Menu) | Type: <span style="color: #003366;">regedit</span> | Navigate to: <span style="color: #003366;">HKEY_CLASSES_ROOT\.php</span></p>
<p><b><img src="http://wincert.net/wp-content/uploads/2011/05/file_preview_explorer1.PNG" alt="" /><br />
</b></p>
<p>Select the .php folder and in the right pane check if you have the following key:</p>
<p><strong>PerceivedType REG_SZ text</strong></p>
<p>If this key isn&#8217;t available, right click on the .php folder and click<span style="color: #003366;"> &#8216;New String Value&#8217;</span></p>
<p>Type: <span style="color: #003366;">PerceivedType</span> | Double click on the newly created key and modify it&#8217;s value to &#8216;<span style="color: #003366;">text</span>&#8216;</p>
<p>Close the Registry Editor and see if you can preview .php files in Explorer now.</p>
<p>On my PC this is working by default, but on some PC&#8217;s, this action is required in order to get the preview working for .php files.</p>
<p>With these changes preview pane in Windows Explorer should work properly.</p>
