Question

我有一份回合列表＆amp;来自JSON页面的团队就像这样......

ROUND | TEAM
-------------
6     | D.C. United
7     | (blank)
8     | New York Red Bulls
8     | Los Angeles Galaxy
9     | Portland Timbers
10    | Chivas USA
11    | Seattle Sounders FC
11    | Houston Dynamo
12    | D.C. United

目前，我正如上面所示回应它，但我希望任何双轮都可以将两支球队展开，而不是分开展示。

以下是我想要展示的一个例子......

ROUND | TEAM
-------------
6     | D.C. United
7     | (blank)
8     | New York Red Bulls & Los Angeles Galaxy
9     | Portland Timbers
10    | Chivas USA
11    | Seattle Sounders FC & Houston Dynamo
12    | D.C. United

这就是我现在正在使用的......我不确定如何修复它。

//get the page 
$str = file_get_contents('http://fantasy.mlssoccer.com/web/api/elements/498/');
$jsonarray = json_decode($str, true);

//count how many entries
$howmanyrounds = count($jsonarray['fixtures']['all']);

//for each entry
for($whichround = 0; $whichround < $howmanyrounds; $whichround++)
{
    //this returns a value like 'Round 6'
    $gameweek = $jsonarray['fixtures']['all'][$whichround][1];
    //Cut out just the number
    $roundno = intval(substr($gameweek, -(strlen($gameweek)-6)));

    //this returns a value like 'Chivas USA (H)'
    $opponents = $jsonarray['fixtures']['all'][$whichround][2];
    //This cuts out the actual team name
    $team = substr($opponents, 0, (strlen($opponents)-4));

    echo $roundno." ".$team."<br>";
}

我尝试了几种不同的方式，但最终都没有达到我想要的效果。这应该很容易。知道怎么做吗？

Answer 1

您可以使用中间数组根据轮次编号将团队分组：

$rounds = array();

for($whichround = 0; $whichround < $howmanyrounds; $whichround++)
{
    // ...
    $rounds[$roundno][] = $team;
}

foreach ($rounds as $roundno => $teams) {
    echo $roundno . " " . join(' & ', $teams)."<br>";
}

Answer 2

尝试将值连接到索引数组中：

$arrJoined = array();

for($whichround = 0; $whichround < $howmanyrounds; $whichround++)
{
    //this returns a value like 'Round 6'
    $gameweek = $jsonarray['fixtures']['all'][$whichround][1];
    //Cut out just the number
    $roundno = intval(substr($gameweek, -(strlen($gameweek)-6)));

    //this returns a value like 'Chivas USA (H)'
    $opponents = $jsonarray['fixtures']['all'][$whichround][2];
    //This cuts out the actual team name
    $team = substr($opponents, 0, (strlen($opponents)-4));

    $arrJoined[$roundno] = ($arrJoined[$roundno] == null ? $team : $arrJoined[$roundno].' & '.$team);
}

然后输出$ arrJoined的内容。

使用它作为中间数组，你应该很好

$str = file_get_contents('http://fantasy.mlssoccer.com/web/api/elements/498/');
            $array = json_decode($str, true);
            $temp = $array['fixtures']['all'];
            $req_array = array();
            foreach($temp as $value)
            {
                list($dummy, $round)  = explode(" ", $value[1]);
                           $value[2] = str_replace('-','',$value[2]);
                if(isset($req_array["Round $round"]) 
                   && ($req_array["Round $round"] != '') 
                   )
                {
                    $req_array["Round $round"] = $req_array["Round $round"]."&".$value[2];
                }
                else if($value[2] != '-')
                {
                    $req_array["Round $round"] = $value[2];
                }
            }

$req_array

的

输出

  Array
   (
    [Round 6] => D.C. United (H)
[Round 7] => 
[Round 8] => New York Red Bulls (A)&Los Angeles Galaxy (A)
[Round 9] => Portland Timbers (H)
[Round 10] => Chivas USA (H)
[Round 11] => Seattle Sounders FC (H)&Houston Dynamo (A)
[Round 12] => D.C. United (A)
 ---
)

我的建议，只是你的代码中的另一个数组（targetAray）并推送该数组中的数据而不是像下面那样打印该数组：

$targetArray = array();   //additional array to store values
//count how many entries
$howmanyrounds = count($jsonarray['fixtures']['all']);

//for each entry
for($whichround = 0; $whichround < $howmanyrounds; $whichround++)
{
    //this returns a value like 'Round 6'
    $gameweek = $jsonarray['fixtures']['all'][$whichround][1];

    //Cut out just the number
    $roundno = intval(substr($gameweek, -(strlen($gameweek)-6)));

    //this returns a value like 'Chivas USA (H)'
    $opponents = $jsonarray['fixtures']['all'][$whichround][2];
    //This cuts out the actual team name
    $team = substr($opponents, 0, (strlen($opponents)-4));

   //below code you need to add. 
   if(array_key_exists($roundno, $targetArray))
     $targetArray[$roundno] = $targetArray[$roundno]. "&" .$team;
   else
    $targetArray[$roundno] = $team;
    echo $roundno." ".$team."<br>";
}
//this will give you your data
print_r($targetArray);

在for循环中将两个条目粘在一起
