到底是json还是数组，求PHP批量插入数据库办法

"; <br>print_r (json_decode($json2, true));echo "<pre class="brush:php;toolbar:false;">";</p>
<p>print_r (json_ecode($json2, true));echo "<pre class="brush:php;toolbar:false;">";</p>
<p>都不管用直接用echo输出</p>
<p>$pageContents = $client->getContent();//getError<br>$pageContents =str_replace('trde_fullo_get_rsponse','',$pageContents);<br>$pageContents =str_replace('"jdp_rese":"{"":{"tde":{','',$pageContents);</p>
