How to Create a Comma-separated List from an Array in PHP

How do I create a comma-separated list from an array in PHP?

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.

Comma separated list from array

so, revising my answer to actually address your question, you could do it with nested foreach loops like this:

<?php

$a1 = array(
    'name' => array( 0 => 'Some message to display1'),
    'test' => array( 0 => 'Some message to display2'),
    'kudos' => array( 0 => 'Some message to display3'),
    );

$final = "";
foreach($a1 as $innerarray){
    foreach($innerarray as $message){
        $final .= $message.", ";
    }
}

echo substr($final,0,-2);
?>

php, how to convert an array containing stdClass Object into comma separated list

Except for the comma separated list, what you have should work in theory, but the code doesn't at all match your array. You state $object not $array and the property is id not nid.

However, just extract the id column and implode. If you have PHP 7:

$list = implode(', ', array_column($output, 'id'));

For older versions:

$list = implode(', ', array_map(function($v) { return $v->id; }, $output));

PHP build an array from a comma separated list
