php fopen returns false but file is readable/writable
<p>have a file that is readable and writable but fopen is returning false...</p>

<pre><code>if(is_readable($file)) echo 'readable ';
if(is_writable($file)) echo 'writable ';
$fp = fopen($file, 'a+');
var_dump($fp);
</code></pre>

<p>result is</p>

<pre><code>readable writable bool(false)
</code></pre>

<p>Any ideas?</p>

<p>sure it must be a permission thing but tried 777 on the file with same results. </p>
