<p><span class="bold"><strong><span class="italic">Note: This section is only applicable to a Unix derivate
system which have the concepts of group and file
ownership.</span></strong></span></p>
<p>There are two additional settings that will allow the control of the group and
file permission settings</p>
<p>
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
<p><code class="code">DEFINE('CACHE_FILE_GROUP','www')</code></p>
</li><li class="listitem">
<p><code class="code">DEFINE('CACHE_FILE_MOD',0664)</code></p>
</li></ol></div><p>
</p>
<p>The <code class="code">CACHE_FILE_GROUP</code> specifies what group should be set on the cached
image file. If this is left empty then the group will be the same as the process
running PHP.</p>
<p>The <code class="code">CACHE_FILE_MOD</code> specifies the file permissions for the image file.
If this is left empty the default permissions used by PHP will be set on the
file.</p>
<p>When PHP is run from the command line (using the PHP CLI version) then the file
permission and group will normally be set to the one of the suer running PHP. Keep
in mind that normally ordinary users are not allowed to change the group to
'<code class="code">www</code>' (the default Apache2 group).</p>
