Question

我有一个变量，其中包含从file_get_contents()函数返回的JSON数据。我无法使用PHP foreach()循环在窗口中显示它

{"meta":{"http_code":200,"network":"instagram","query_type":"trends"},"posts":[{"text":"റിലീസിന് മുന്നേ കുടുംബ പ്രേക്ഷകർ സ്വീകരിക്കുമോ എന്ന് ഭയന്ന ചിത്രത്തെ വൻ വിജയമാക്കിയത് അതെ കുടുംബ പ്രേക്ഷകർ തന്നെ !! അതിരൻ മികച്ച പ്രേക്ഷകാഭിപ്രായം നേടി മുന്നേറുന്നു#fahadfazil #saipallavi #renjipanikar #greencupmedia #greencupads","lang":null,"sentiment":"neutral","network":"instagram","type":"photo","posted":"2019-04-19 08:12:03","postid":"2025358113105232226","image":"https://scontent-lga3-1.cdninstagram.com/vp/164a0365a1bbef1ba5e8a789d17dd53a/5D918580/t51.2885-15/e35/56935396_299716390947661_5372448290966971990_n.jpg?_nc_ht=scontent-lga3-1.cdninstagram.com","url":"https://www.instagram.com/p/BwbhHkal8Fi","user":{"userid":"12163891362"},"urls":null,"tags":[{"text":"fahadfazil","url":"https://www.instagram.com/explore/tags/fahadfazil"},{"text":"saipallavi","url":"https://www.instagram.com/explore/tags/saipallavi"},{"text":"renjipanikar","url":"https://www.instagram.com/explore/tags/renjipanikar"},{"text":"greencupmedia","url":"https://www.instagram.com/explore/tags/greencupmedia"},{"text":"greencupads","url":"https://www.instagram.com/explore/tags/greencupads"}],"user_mentions":null,"popularity":[{"name":"likes","count":8},{"name":"comments","count":0}]}]}

通知：未定义的属性：stdClass :: $第16行的C：\ xampp \ htdocs \ insta3 \ index.php中的帖子

注意：尝试在第16行的C：\ xampp \ htdocs \ insta3 \ index.php中获取非对象的属性

            <?php 

             $url = 'http://api.social-searcher.com/v2/trends?q=renjipanikar&network=instagram&limit=1'; // path to your JSON file
            #get the data
            $json = file_get_contents($url);

            #convert to php array
            $php_array = json_decode($json);
             $datais=json_encode($php_array,JSON_UNESCAPED_UNICODE|JSON_UNESCAPED_SLASHES);

            echo '<br><br>'; 

                 //print_r($datais);


             echo $php_array->meta->posts[0]->text[0];



             ?>

我希望收到，文本，点赞和评论数之类的数据

Json数据到PHP循环
