Is it json or array? How can I batch insert into the database using PHP?

As shown in the picture, is it json or array?
print_r (json_decode($json2)); echo "

"; <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>If it doesn’t work, just use echo to output</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>
