通过将php数组转换为json而无法获得所需的输出
问题描述：
I receive names and links of some files from an external website and convert it into a JSON string using the following code:
<?php
include('simple_html_dom.php');
$f = $_GET['f'];
$w = "www.something.com";
$dom = file_get_html($w);
$arr = array("file" => array());
foreach($dom->find('div[id=file_html] div[id=right_data]') as $top){
$n = $top->find('div', 0)->childNodes(0)->innertext;
$l = $top->find('div', 2)->childNodes(0)->childNodes(0)->childNodes(0)->href;
$jj[] = array('name' => $n, 'link' => $l);
}
array_push($arr['file'], $jj);
echo json_encode($arr);
?>
The output I expect is
{"songs":[{"name":"file1","link":"link1"},{"name":"file2","link":"link2"}]}
But the output i get is:
{"songs":[[{"name":"file1","link":"link1"},{"name":"file2","link":"link2"}]]}
Could someone kindly point out the error in my code? Thank you

Remove this one,
$arr = array("file" => array());
after iteration of foreach()
foreach($dom->find('div[id=file_html] div[id=right_data]') as $top){
// as it is....
}
$arr['file'] = $jj;
