DEDE How to call other field values ​​in the runphp=yes tag?

DEDE Dreamweaver CMS template uses the method of calling other field values ​​​​in the runphp=yes tag

Recommended learning: Dreamweaver cms

dedecms calls other field values ​​​​in the tag of runphp=yes dedecms has a powerful TAG customization function, but if you are in the case of runphp=yes, you cannot use tags such as [field]

Because it cannot be parsed (it is regarded as PHP code, how can it be parsed?)

What should I do?

I checked Google and found no solution. So I thought for a long time and came up with a temporary solution, which is to use global variables to solve this problem. .

{dede:php}$GLOBALS['xxoo']=$arc->Fields['fieldname']{/dede:php} 
{dede:field.xxxx runphp="yes"}@me="test".@me."-test".$GLOBALS['xxoo'];{/dede:field.xxxx}

That is, first open a PHP tag and replace the value you want to assign to the global variable. Then assign the field value to him in another run.
