PHP5 compatability

From http://de2.php.net/json_encode:
json_encode
(PHP 5 >= 5.2.0, PECL json:1.2.0-1.2.1)

In drasticCommon.class.php you use on line 56:
json_encode($GLOBALS['drasticsettings'])

this means the tool will only work from PHP version 5.2.0 and higher.
I would be happy to use this tool with 5.1 or even 4.4.4 which are still very common amongst large user communities (and even providers!)

As was stated correctly in the Prerequisites of DrasticTools.txt:
- Json installed (see http://www.json.org), Json is installed by default in the latest php release.

Sorry, I should have read this readme first...

By the way, by using your ported PHP4 version I cannot update and delete records (when using PHP 5.1).

yes, you are right JSON install is necessary.
json.org explains possibilities to add JSON support if you don't have a PHP version with it installed by default, but of course the most easiest way is to install a PHP version with JSON support.

PHP4 version: well, someone else added this port and it used to work for him. I am not familiar with the port itself, so cannot advise you on this one.

I have also run into this problem. There is a fairly simple solution, though. Download the JSON PEAR package ( http://pear.php.net/pepr/pepr-proposal-show.php?id=198 ) and install it. Then you'll need to add the following into the constructors for drasticMySQL.class.php and drasticCommon.class.php.

include_once 'Services/JSON.php';
$json = new Services_JSON();
$this->json = $json;

Then, change all instances of 'json_encode' to '$this->json->encode' and you should be good. Let me know if you have any problems with this, as I might have missed something.
