Create a loop over the parent array or use array_map. @ankitsuthar – Oladipo Jun 16 '17 at 07:12

Directly from the docs:

$comma_separated = implode(",", $array);

I used implode with a little modification. Since I needed a comma-separated list with single quotes as well, I used the following on my array: $innie = implode("', '", $arrayDistricts); [Note the single quotes inside the double quotes.] Then I used this in my query: IN ('$innie') [Note the single quotes around the variable.] – KiloVoltaire Aug 09 '15 at 03:27
Thanks Kilo thats exactly what i was looking for. I am using it in a bulk update – Sweet Chilly Philly Feb 08 '19 at 02:22

Make your array a variable and use implode.

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

echo $comma_separated; // lastname,email,phone

You're looking for implode()

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