php数据库数组json,到底是json还是数组，求PHP批量插入数据库办法

如图到底是json还是数组

print_r (json_decode($json2));echo "

";      

print_r (json_decode($json2, true));echo "

";      

print_r (json_ecode($json2, true));echo "

";      

都不管用直接用echo输出

$pageContents = $client->getContent();//getError

$pageContents =str_replace('trde_fullo_get_rsponse','',$pageContents);

$pageContents =str_replace('"jdp_rese":"{"":{"tde":{','',$pageContents);

echo $pageContents;
