PHPLD Meta_Keywords Display on Page

[Mannan]

Hello PHP Freaks,

 

I need an immediate help to display META_KEYWORDS as separate link on page but while i'm doing it my all keywords will be single link like:

 

nike shoes, armani jeans, gucci shoes 

 

<a href="{$smarty.const.DOC_ROOT}/{$link.CATEGORY_URL|escape|trim}" title="{$link.META_KEYWORDS|escape|trim}">{$link.META_KEYWORDS|escape|trim}</a>

 

can any body tell me that how I will link my three keywords separately???

 

also I tried

 

print_r(explode(',', $link.META_KEYWORDS));

 

but its gives me errors please help me out I'll be very thank full!
