如何将json数据从网址发送到数据库并进行更新

Question

Hy，

我只是无法弄清楚如何让这个工作。

如何将home> name，home>分数发送到数据库（相同），并将状态，轮次和日期时间发送到数据库。 但是，如果json url的更改比更新数据库更新，并且如果有新的匹配，则插入它。

这一切都需要自动完成。

[ 
    { 
    "url":"http://www.gosugamers.net/counterstrike/tournaments/10423-starladder-cis-minor-championship-cologne-2016/2865-playoffs/10426-playoffs/matches/113497-worst-players-vs-team-empire", 
    "home":{ 
    "name":"Worst Players", 
    "url":"/counterstrike/teams/15191-worst-players", 
    "country":"Russian Federation", 
    "rank":57, 
    "score":1 
    }, 
    "away":{ 
    "name":"Team Empire.", 
    "url":"/counterstrike/teams/14464-team-empire", 
    "country":"Russian Federation", 
    "rank":40, 
    "score":2 
    }, 
    "status":"Complete", 
    "type":"counterstrike", 
    "rounds":"Best of 3", 
    "valueBet":true, 
    "datetime":1462024800 
    }, 
    { 
    "url":"http://www.gosugamers.net/counterstrike/tournaments/10296-esports-championship-series-season-1/2810-online-phase/10298-north-american-league/matches/111367-team-liquid-cs-vs-counter-logic-gaming-cs", 
    "home":{ 
    "name":"Team Liquid.CS", 
    "url":"/counterstrike/teams/10561-team-liquid-cs", 
    "country":"United States", 
    "rank":10 
    }, 
    "away":{ 
    "name":"Counter Logic Gaming.CS", 
    "url":"/counterstrike/teams/10569-counter-logic-gaming-cs", 
    "country":"United States", 
    "rank":39 
    }, 
    "status":"Upcoming",

    "rounds":"Best of 3", 
    "valueBet":true, 
    "datetime":1462068000 
    } 
] 

我已经试过这个代码

<?php 

include("../../check.php"); 

$urljson = "http://localhost:5000/matches"; 
$json = file_get_contents($urljson); 
$data = json_decode($json, TRUE); 
$home = $data[0]['home']; 
$away = $data[0]['away']; 
$status = $data[0]['status']; 
$type = $data[0]['rounds']; 
$timestamp = $data[0]['datetime']; 


foreach($data as $array) { 
    echo $home['name']; 
    echo '<br>'; 
    echo $home['score']; 
echo '<br>'; 
echo $away['name']; 
echo '<br>'; 
echo $away['score']; 
echo '<br>'; 
echo $status; 
echo '<br>'; 
echo $type; 
echo '<br>'; 
echo $timestamp; 
echo '<br>'; 
echo '<br>'; 
} 


?> 

但这是网页给我（它显示了同样的结果多发次）

我希望有人可以帮助我，因为我被卡住了4天。

因为您在循环内部使用了错误的变量，所以您始终得到相同的数据。使用你的情况$数组变量：

foreach($data as $array) { 
    echo $array['name']; 
    echo '<br>'; 
    echo $array['score']; 
    echo '<br>'; 
    ... etc. 
} 

也许这将是很好的调用变量$行或$匹配，而不是$阵列以提高可读性。

您会看到“Notice：Undefined ...”，因为有些JSON节点没有得分。

<?php 

include("../../check.php"); 

$urljson = "http://localhost:5000/matches"; 
$json = file_get_contents($urljson); 
$data = json_decode($json, TRUE); 

foreach($data as $match) { 
    echo $match['home']['name']; 
    echo '<br>'; 
    if (isset($match['home']['score'])) { 
     echo $match['home']['score']; 
     echo '<br>'; 
    } 
    echo $match['away']['name']; 
    echo '<br>'; 
    if (isset($match['away']['score'])) { 
     echo $match['away']['score']; 
     echo '<br>'; 
    } 
    echo $match['status']; 
    echo '<br>'; 
    echo $match['rounds']; 
    echo '<br>'; 
    echo $match['datetime']; 
    echo '<br>'; 
    echo '<br>'; 
} 

?>
