Question

 exception 'ErrorException' with message 'Illegal string offset 'tax''

这是我得到的致命错误

        Log::error(print_r($pax_group , true));
        Log::error(var_dump($pax_group));
        if(isset($pax_group["otherdetail"]["tax"]["details"]["detail"][0]))
                            {
                               // I get the fatal error at the foreach line
                                foreach($pax_group["otherdetail"]["tax"]["details"]["detail"] as $one_tax)
                                {
                                    $detail = new Otherdetail;
                                    $detail->occ_paxs_id = $px->id;
                                    $detail->code = $one_tax["code"];
                                    $detail->amount = $one_tax["amt"];
                                    $detail->B2Bamount = $one_tax["amt"];
                                    $detail->save();
                                }
                            }

这是我在otherdetail里面的价值：<otherdetail>0</otherdetail>

当<otherdetail>0</otherdetail>内没有[“tax”] [“details”] [“detail”] [0]时，任何人都知道我怎么可能通过isset？

编辑：我现在能够重现它。这就是我在print_r和var_dump log

中的内容

Answer 1

试试这个：

if(isset($pax_group['otherdetail']) && isset($pax_group['otherdetail']['tax']) && isset($pax_group['otherdetail']['tax']['details']) && isset($pax_group['otherdetail']['tax']['details']['detail'])){
  //...
}

aset后发生致命错误？
