@_ is the automagically created array containing all calling parameters (the array that you use when you access $_[x]). And if there's more than one array to pass around, refs are definitely the way to go, unless you have some other way to discern one array from the other.

implode - Join array elements with a string
SYNOPSIS
string implode (string $glue, array $pieces)
DESCRIPTION
string implode (array $pieces)
Join array elements with a $glue string.
Note
implode(3) can, for historical reasons, accept its parameters in either order. For consistency with explode(3), however, it may be
less confusing to use the documented order of arguments.
PARAMETERS
o $glue
- Defaults to an empty string.
o $pieces
- The array of strings to implode.
RETURN VALUES
Returns a string containing a string representation of all the array elements in the same order, with the glue string between each ele-
ment.
EXAMPLES
Example #1
implode(3) example
<?php
$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);
echo $comma_separated; // lastname,email,phone
// Empty string when using an empty array:
var_dump(implode('hello', array())); // string(0) ""
?>
NOTES
Note
This function is binary-safe.

explode(3), preg_split(3), http_build_query(3).
