Can't Return When Looping - php

Question

Why I can't return while looping in function? Why I just got 1 result like without looping? Here is my code:
function search($get){
$i=0;
//print_r($get);
foreach($get->itemlist as $song){
$i++;
$ch = curl_init('');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIE, 'wmid=14997771; user_type=2; country=id; session_key=96870dd03ab9280c905566cad439c904;');
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36');
$json = curl_exec($ch);
$json = str_replace('MusicInfoCallback(', '', $json);
$json = str_replace(')', '', $json);
$json = json_decode($json);
$songurl = $json->mp3Url;
//print_r($json);
return array($i => array("song" => $json->msong,
"singer" => $json->msinger,
"url" => $song->songid));
}
}
print_r(search("key"));
any alternative?

Untested Code:
function search($get){
foreach($get->itemlist as $song){
$ch = curl_init('');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIE, 'wmid=14997771; user_type=2; country=id; session_key=96870dd03ab9280c905566cad439c904;');
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36');
$json = curl_exec($ch);
$json = json_decode(substr($json,18,-1),true);
$results[]=['songurl'=>$json['mp3Url'],
'song'=>$json['msong'],
'singer'=>$json['msinger'],
'url'=>$song->songid
];
}
return $results;
}
I don't have any sample data to verify my code with. I am making an assumption that 'MusicInfoCallback( and ) are the start and end of the curl string. I recommend packing all data into an (automatically) indexed array.
$songurl was also "trapped" within the scope of the function.
