如何将数据从 json 检索到 php 输出。 php代码。

<?php
$json = '{"data":{"bid":[{"cid":"1244343","crid":"1090868","creativeId":0,"lastUpdateTime":1587667678,"credits":1,"ext":{"type":"VIDEO","class":0,"xButtonBehavior":"buttonHidden","templateid":"0","notificationsData":{"duringData":"","afterData":"","nextData":"Next"},"counterData":{"completionCountdown":30,"timeUntilTimer":0,"showTimer":false,"percentage":false},"videoData":{"autoPlay":true,"videoType":"ssa-internal-video-player","videoTime":30,"videoSource":{"videoformat_mp4":"https://cdn.com/files/videos.mp4","html":""},"videoPoster":""},"enableLogo":true,"removeNext":true,"appData":{"appIcon":"https://platform.com/banners/images.png","title":"FarmVille 2: Country Escape","description":"app","appImages":["https://cdn.com/image/a.jpg"],"adAssets":{"both":["https://cdn.com/image/a.jpg"]},"appId":"com.escape","appSize":120,"numOfReviews":2765261},"clickTags":{"index":1,"clickURL":"https://playog.com","title":"DOWNLOAD NOW","pixURL":"https://hapons.com"},"callbacks":{"imp":[{"at":0,"url":"https://comenicad.com","percentage":false,"type":"pix"}],"29":[{"at":29,"url":"https://pixtra.com","percentage":false,"type":"pix","event":"notify"}]},"features":{"wiggle":true,"allowHybrid":false,"isVideoClickable":true,"externalBrowser":false,"ccvaf":false,"allowNativeEndCard":false},"forceOrientation":"Landscape","opportunityID":"opp_101","orderID":47053}}],"ext":{"requestID":"2f6158b1-8996-11ea-bb55-41b78e2aaca7","auction":{},"randomSeed":850307660,"numOfBannersToCache":1,"numOfBannersToInitSuccess":1,"landingId":10356,"strategyId":197,"refreshInterval":30,"DEC":3,"purgeCacheOnInit":false,"allowMultiInitCalls":false,"openLandingPageInExtBrowser":false,"pagination":false,"labels":{"confirmCloseMsg":{"during":{"close":"No rewards earned yet!

$jsondata=json_decode($data);

print_r($jsondata->{'clickTags'}[0]->{'clickURL'}); //output blank/not working
echo "<br />"; 

print_r($jsondata->{'imp'}[0]->{'url'}); //output blank/not working
echo "<br />";

print_r($jsondata->{'29'}[0]->{'url'}); //output blank/not working
echo "<br />";

找人帮我写正确的php代码？

【问题讨论】：

您需要print_r($jsondata); 才能看到结构。 $jsondata->data->bid[0]->ext-> clickTags->clickURL等等等等……
而且不输出空白。打开错误报告注意：未定义变量：数据注意：尝试获取非对象的属性“clickTags”注意：尝试访问类型为 null 的值的数组偏移量注意：尝试获取非对象的属性“clickURL”对象
注意：试图获取非对象的属性'imp'
注意：尝试访问 null 类型值的数组偏移量注意：尝试获取非对象的属性 'url'
注意：尝试获取属性 '29' 的非对象注意：尝试访问 null 类型值的数组偏移量注意：尝试获取非对象的属性“url”

【解决方案1】：

请试试这个：

print_r($jsondata->data->bid[0]->ext->clickTags->clickURL); 
echo "<br />"; 

print_r($jsondata->data->bid[0]->ext->callbacks->imp[0]->url); 
echo "<br />";

print_r($jsondata->data->bid[0]->ext->callbacks->{29}[0]->url); 
echo "<br />";
