到底是json還是數組，求PHP批次插入資料庫辦法

如圖到底是json還是陣列
print_r (json_decode($json2));echo "

"; <br>print_r (json_decode($json2, true));echo "<pre class="brush:php;toolbar:false">";
<p>print_r (json_ecode($json2, true));echo "</p><pre class="brush:php;toolbar:false">";
<p>都不管用直接用echo輸出</p>
<p>$pageContents = $client->getContent();//getError<br>$pageContents =str_replace('trde_fullo_get_rsponse','',$pageContents);<br>$pageContents =str_replace('"jdp_rese":" tde":{','',$pageContents);</p>
<p>echo $pageContents;</p>
<pre class="brush:php;toolbar:false"><code>tid":2356471828086946,"buyer_nick":"图图爱跳舞","created":"2016-09-16 11:24:05","payment":"657.97","pay_time":"2016-09-16 11:24:22","modified":"2016-10-08 21:03:55","num":1,"price":"1985.00","receiver_name":"小百度","receiver_address":" 十里铺先行大厦（务必联系周冰签收！）","status":"TRADE_FINISHED","total_fee":"2054.97","num":1,"oid":2356471828086946,"outer_iid":"gncfastact240x2","payment":"657.97","status":"TRADE_FINISHED","title":"GN美国原装口香糖","price":"1985.00"</code>
