returning json from the lastfm api - php

Question

So I am trying to create a jquery/ajax autocomplete form that uses the last.fm api to autocomplete the title of a song to whatever the user is typing, the problem im having is that I can not seem to get the last fm data to return in the proper json format. this is the format that my jquery plugin (link to autocomplete) would like returned:
{
"suggestions": [
{ "value": "United Arab Emirates", "data": "AE" },
{ "value": "United Kingdom", "data": "UK" },
{ "value": "United States", "data": "US" }
]
}
and here is essentially what im doing in my php script the returns the json to the autocomplete plugin:
$titleName = "what's my age";
$limit = 1;
$results = Track::search($titleName, $limit);
print_array($results);
echo "<ul>";
while ($title = $results->current()) {
echo $limit;
echo "<li><div>";
echo "Artist: " . $title->getArtist() . "<br>";
echo "Album: " . $title->getAlbum() . "<br>";
echo "Duration: " . $title->getDuration() . "<br>";
echo "getWiki: " . $title->getWiki() . "<br>";
echo "name: " . $title->getName() . "<br>";
echo "</div></li>";
$jsonArray['suggestions'] = array('Name'.$limit => $title->getName(), 'Artist'.$limit => $title->getArtist());
$limit++;
$title = $results->next();
}
echo "</ul>";
print_array($jsonArray);
echo json_encode($jsonArray);
the echo and print statments are just for testing, but this is what the json_encode is returning:
{"suggestions":{"Name2":"Blink vs. Jay-Z - what's my age again","Artist2":"Dj Tech1"}}
and this is what is being returned (via the echo testing):
1
Artist: Blink 1-82
Album:
Duration: 0
getWiki:
name: What's My Age Again?
2
Artist: Dj Tech1
Album:
Duration: 0
getWiki:
name: Blink vs. Jay-Z - what's my age again
so i know the code is working properly so is the sdk autocomplete etc. i also understand that am deleting the array in the while loop each time it loops through and i have not worked a fix out for that yet, but that issue aside, the json is not returning in the requested format and i can not seem to find the proper way to construct the array in order to get it in the proper format, any ideas?

Answer 1

$suggestionsArr['suggestions'] = [];
foreach (range(1,3) as $key => $value) {
array_push($suggestionsArr['suggestions'], ['name' => 'Song1', 'artist' => 'Artist1']);
}
echo json_encode($suggestionsArr);
