Yes you can do this by using implode
$string = implode(', ', $tags);
And just so you know, there is an alias of implode, called join
$string = join(', ', $tags);
I tend to use join more than implode as it has a better name (a more self-explanatory name :D )

Community warning: If that string comes from a csv file, use of
str_getcsv()instead is strictly advised, as suggested in this answer
Try explode:
$myString = "9,admin@example.com,8";
$myArray = explode(',', $myString);
print_r($myArray);
Output :
Array
(
[0] => 9
[1] => admin@example.com
[2] => 8
)

$string = '9,admin@google.com,8';
$array = explode(',', $string);
For more complicated situations, you may need to use preg_split.

You want to use implode for this.
ie:
$commaList = implode(', ', $fruit);
There is a way to append commas without having a trailing one. You'd want to do this if you have to do some other manipulation at the same time. For example, maybe you want to quote each fruit and then separate them all by commas:
$prefix = $fruitList = '';
foreach ($fruits as $fruit)
{
$fruitList .= $prefix . '"' . $fruit . '"';
$prefix = ', ';
}
Also, if you just do it the "normal" way of appending a comma after each item (like it sounds you were doing before), and you need to trim the last one off, just do $list = rtrim($list, ', '). I see a lot of people unnecessarily mucking around with substr in this situation.

This is how I've been doing it:
$arr = array(1,2,3,4,5,6,7,8,9);
$string = rtrim(implode(',', $arr), ',');
echo $string;
Output:
1,2,3,4,5,6,7,8,9
Live Demo: http://ideone.com/EWK1XR
EDIT: Per @joseantgv's comment, you should be able to remove rtrim() from the above example. I.e:
$string = implode(',', $arr);

I would turn it into CSV form, like so:
$string_version = implode(',', $original_array)
You can turn it back by doing:
$destination_array = explode(',', $string_version)

I would turn it into a json object, with the added benefit of keeping the keys if you are using an associative array:
$stringRepresentation= json_encode($arr);

$values = {"data": "key=abc, val=123, key=abc, val=456,...")
How may i parse this to get an array or array map of all keys and vals?
Have tried till here:
$values = array_map(function ($value){
list($key, $value) = explode("=", $value);
return [ 'value' => $value ];
}, explode(',' , $data));I exploded twice, but its nowhere close.. pls help!

You have two explodes and an array map. Since it isn't working, I suggest you take it one step at a time. Start with the explode on comma... Do just that explode and print the result. is it what you expect? If not, fix it then continue. Then move on to the array map... Print each value. Is it getting what you think? Then the list()... Print key and value. Is it splitting like you think? Basically, debug it step by step, print intermediate results to make sure each step is doing what you'd expect.

Looking at your input example, you have an alternating key=/val= string between each comma. So when you explode on comma, each value of the resulting array will alternate between a key= and val= string. The basic logic then, is to check which item you have and process keys and values separated and combine them after. I think a foreach will be easier to understand than array_map. The problem however, is that key=abc appears twice, so it's impossible to have a simple (one level) associative map. For example, this will be invalid, because of duplicated keys: $map = [ 'abc' => '123', 'abc' => '456', ]; So you need to first decide how you want the end array to look like. Post it here what you expect and I will come up with an example solution. This is a sample I wrote showing the problem: https://3v4l.org/NZo7e#v8.1.9

This should work for you:
(Here I just get the column which you want with array_column() and simply implode it with implode())
echo implode(",", array_column($myAssociativeA, "type"));

Another option is to use array_walk() to return the key you want:
array_walk($myAssociativeA, function(&$value, $key, $return) {
$value = $value[$return];
}, 'type');
echo implode(', ', $myAssociativeA); // cat, dog
Useful for older PHP versions - @Rizier123's answer using array_column() is great for PHP 5.5.0+
