How do I input multiple values that are comma-separated into a table?

Question

Disclaimer: I am completely new to PHP and MySQL/SQL.

I have multiple implode()functions for my arrays. I want to be able to have the arrays input into the table separated with commas to avoid confusion.

  $company_state = implode($_POST['companystate']);

The output looks like this in the table and when echo:

Company state: ILMEMDNVOHOK

But I want it to look like this within the table:

Company state: IL, ME, MD, NV, OH, OK

Is there any way I can get it to do this?

Here is the code for the form:

<label for="companystate[ ]">Company state:</label><br />

Thanks in advance. And also could you explain to me what each function does? I'm still learning and most of PHP/SQL is still gibberish to me.

Answer 1

Try this:

$company_state = implode(",", $_POST['companystate']);

Answer 2

You just need to pass in some glue for your implode:

implode(', ', $_POST['companystate']);
