How to fix PHP installation chartdirector in Windows environment

PHP installation Chartdirector under Windows environment
Need to use PHP to draw a candlestick chart, Baidu said after the chartdirector can be used, after downloading
Local access: http://localhost/k/ChartDirector/lib/FinanceChart.php
Error occurred
Error Loading chartdirector for PHP Extension

And then know that to be configured, my PHP Version 5.5.1,
How do I configure it?
Do you want to put Phpchartdir550.dll in the folder containing php.ini?
Then add Extension=c:/xampp/htdocs/k/chartdirector/lib/phpchartdir550.dll to the php.ini?


I hope the great God to help me answer, thank you ...

Yes
He also needs Chartdir.dll support, note the placement
In fact, his help document is very clear (but all in English)

I don't think this thing works well, it is estimated that he has poor support for Chinese.
