How to convert array to a string using methods other than JSON?

Question

What is a function in PHP used to convert array to string, other than using JSON?

I know there is a function that directly does like JSON. I just don\'t remember.

Use the implode() function:

$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);
echo $comma_separated; // lastname,email,phone
