Try implode(', ', $array) function.

You can use implode.

$string = implode( ',', $array );

Likewise, you can then return the string to an array with explode.

$array = explode( ',', $string );

Say hello to the implode function in PHP:

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

---

You can use the implode function :

$your_array = array('a', 'b', 'c', 'd');
$string = implode(',', $your_array);
echo $string;

Will get you this output :

a,b,c,d

Note that ',' have been added between the array's elements, and not at the beginning nor the end of the string.
