Answer 1

You can use array_map;

$temp = array_map(function($i){return $i['name'];}, $myarray); 

$output = implode(',', $temp);

Answer 2

You can do it in many ways. One way to do it with array_column() and implode()

<?php
$myarray = array(array('name' => 17),array('name' => 18),array('name' => 19));
$one_d = array_column($myarray, 'name');
echo implode(',',$one_d);
?>

A simple foreach could also do the trick.

$var = '';
foreach ($myarray as $value) {
    $var .= $value['name'].',';
}
$var = substr($var, 0, -1);
echo $var; // 17,18,19
