数组转换,该如何处理

数组转换
有一数组：

PHP code

$input = array("13546465"=>1,"3123123"=>1,"221112"=0);

PHP code

$output = [msg,{"tel":"13546465"，"status":"1"},{"tel":"3123123"，"status":"1"},{"tel":"221112"，"status":"0"}]

PHP code

$input = array("13546465"=>1,"3123123"=>1,"221112"=>0);$r[] = 'msg';foreach($input as $k=>$v)  $r[] = array('tel' => "$k", 'status' => "$v");$output = json_encode($r);echo $output;
