serialize question

I’m doing some serializing in my model and the table fields are setup as “text” types, yet the output looks sort of strange -

Category ID — - “2”

  • “6”
  • “8”
  • “”
  • “” State ID — - “3”
  • “6”
  • “7”
  • “9”
  • “10” Term ID — - “3”
  • “8”
  • “2”
  • “7”
  • “” Looks weird or no ? Is all I need maybe is some regex to strip the hyphens and do some nice formatting ? I’m also going to be passing these values into a query so would clean up be necessary then as well ?

TIA Stuart
