Turning an array into a string

There are a couple of ways of turning arrays into strings in PHP.

The key is to pass the delimiter that you want to use to implode from the array to the string.

You can use join or you can use implode.

For most instances implode is all you will need.

Just do it like this:
$mystring = implode(",",$myarray);

that will then create a string of the members of $myarray separated by a comma.
