, array $pieces
)$pieces

Note:
implode() can, for historical reasons, accept its parameters in either order. For consistency with explode(), however, it may be less confusing to use the documented order of arguments.
glue
Defaults to an empty string.
pieces
The array of strings to implode.
Returns a string containing a string representation of all the array elements in the same order, with the glue string between each element.

Example #1 implode() 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) ""
?>
