?Arrays in vBulletin options and use these in templates? It's Possible

[Jhonnyf]

I'm create a Option Page for mi plugin and use a free field to write the ID of user separating with ","

But In templates I can't use this like a array in a condition to use the "in_array function" or explode to create the array... maybe exist another form to do that or necessarily I should be use a plugin to create the array and use in the templates

Thank You
