you need this

PHP Code:

Float:GetDistanceBetweenPoints(Float:x1,Float:y1,Float:z1,Float:x2,Float:y2,Float:z2)
{
    return floatsqroot(floatpower(floatabs(floatsub(x2,x1)),2)+floatpower(floatabs(floatsub(y2,y1)),2)+floatpower(floatabs(floatsub(z2,z1)),2));
} 


or you can simply use

PHP Code:

GetPlayerDistanceFromPoint 


like this

PHP Code:

distance = floatround(GetPlayerDistanceFromPoint(playerid, x[0],y[0],z[0]));
