亲们，帮忙处理一下数据格式

Question

一段字符串 $str = "[{"phone":"01081733730","name":"物业"},{"phone":"15811518151","name":"贾章亮"},
{"phone":"15263529626","name":"史三"},{"phone":"4007883333","name":"客服助手"}]";
现在想把字符串中的phone的值给拿到，成为一个数组
array("物业"=>"01081733730","贾章亮"=>"15811518151","史三"=>"15263529626","客服助手"=>"4007883333");

Answer 1

foreach(json_decode($str) as $v) {
  $res[$v->name] = $v->phone;
}
$res 就是

Answer 2

亲，加入我现在处理完后，我应该怎么在变回去呢？
array(6) {
  ["物业"] => string(11) "01081733730"
  ["贾章亮"] => string(11) "15811518151"
  ["史三"] => string(11) "15263529626"
  ["王五"] => string(3) "135"
  ["李四"] => string(3) "134"
  ["张三"] => string(3) "133"
}  
在原始数据上添加了几条数据，然后还变成
$str = "[{"phone":"01081733730","name":"物业"},{"phone":"15811518151","name":"贾章亮"},
{"phone":"15263529626","name":"史三"},{"phone":"135","name":"王五"},{"phone":"134","name":"李四"},{"phone":"133","name":"张三"}]";  这样的字符串

foreach ($temArr as $k => $v) {
                $new_data[] = array(
                    'phone' => $v,
                    'name' => $k
                );
            }
            $new_data = json_encode($new_data,JSON_UNESCAPED_UNICODE);
自己搞定了

Answer 4

数组中拿出一列， array_column()
