Answer 3

Save yourself some lines of code:

var availableTags = <?php
function get_tag($value) {
    return $value['tag'];
}
echo json_encode(array_map("get_tag", $Tags));
?>

Answer 4

Try:

var availableTags = <?php
echo json_encode(array_map(create_function('$v','return $v[\'tag\'];'), $Tags));
?>;

Answer 5

<?php 
$arr = array(
0 => array("id" => 9826, "tag" => "php"),

1 => array("id" => 9680, "tag" => "perl")
);

$my_array;

foreach($arr as $key=>$val) {
   $my_array[] = $arr[$key]['tag'];
}

$availableTags = json_encode($my_array);
echo $availableTags;
?>
