title: PHP file_exists stopped working this morning?
body: <p>Just wondered, I have the following code:</p>
  
  <pre><code>            &lt;a href="&lt;?=$row-&gt;aw_deep_link?&gt;"&gt;
                  &lt;?php if (file_exists($_SERVER['DOCUMENT_ROOT'] . 'images/products/' . $row-&gt;strId . '.jpg')):?&gt;
  
                  &lt;img alt="&lt;?=$row-&gt;my_brand . ' ' . $row-&gt;line . ' ' . $row-&gt;my_product . ' - ' . $row-&gt;size.$row-&gt;unit?&gt;" height="170" itemprop="image" src="&lt;?=base_url() . 'images/products/' . $row-&gt;strId?&gt;.jpg" width="170"&gt;
                  &lt;?php else:?&gt;
  
                  &lt;img alt="&lt;?=$row-&gt;my_brand . ' ' . $row-&gt;line . ' ' . $row-&gt;my_product . ' - ' . $row-&gt;size.$row-&gt;unit?&gt;" height="170" itemprop="image" src="&lt;?=$row-&gt;aw_image_url?&gt;" width="170"&gt;
                  &lt;?php endif;?&gt;
  
              &lt;/a&gt;
  </code></pre>
  
  <p>Up until last night, this was performing perfectly; this morning - it's stopped, out of the blue and automatically defaults to the </p>
  
  <blockquote>
    <p>else</p>
  </blockquote>
  
  <p>clause.</p>
  
  <p>Has something changed with PHP?</p>
