Is there a follow() function or a $playerx,y,z variable?

i need it to work like this :

Player says "follow"
the targeted NPC follows the player

The player gives an npc an item and the npc makes a soldier where the player is standing

if ($item0 == "903") { say("A Guard has been placed where you are standing!") spawn(180005,0,7,$playerx,$playery,$playerz) }

Nevermind the follow command is follow("$name")

Now what about the playerx,y,z variables? any 1 know those ?
