How to check PHP configuration
In order to see the PHP configuration that is used in SquirrelMail, you should create a file with PHP extension (for example: test.php) and add the following text:
<code>
<?php phpinfo(); ?>
</code>
The file must be stored in same directory that stores other SquirrelMail scripts.
After creating the file, open it in a browser. For example: http://example.org/squirrelmail/test.php
The [phpinfo() function] displays the used PHP configuration. Settings listed in the local column are the settings applied to SquirrelMail scripts.
Note that because the information provided by this function can be (security) sensitive, it is recommended that you either disable (you can do so by simply commenting it out (by adding two forward slashes in front of the function call "//")) or remove this file after you are done testing.
WARNING! Make sure that you don't have an active SquirrelMail session when you test your PHP settings, because the output from phpinfo() will include your login information. If that's the case, don't post your test results online.
