如何通过查询遍历从mysql数据库表创建的数组，并在另一个php文件中使用该数组？

我对php非常陌生，我真的尝试了几天来找到一个解决方案，我觉得我几乎做到了，但仍然没有成功。如果有人能帮助我，我会非常高兴。我正在建立一个预测足球的新网站。我在mysql中有一个表，我可以成功地获得我需要的所有行。我也在用一种很好的方式将数据存储在一个数组中

这是我获取行并将它们存储在数组中的第一个php，我还需要列数据，因为在新查询的第二个php中需要它们

文件名filtere1_danimarka.php

<?php

include 'tableNameDanimarka.php';
include 'indexDanimarka.php';
include 'connectionDatabase.php';


$sql = "SELECT * 
        FROM $tableName 
        where NOT A ='*' ";



$result = $conn->query($sql);
$array = array();
if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
$array[] = $row; 
}

for($i = 0, $j = count($array); $i < $j ; $i++){
 $B= $array[$i]['B'];
 $F = $array[$i]['F'];
 $E = $array[$i]['E'];
 $O = $array[$i]['O'];
 $Home = $array[$i]['HOME'];
 $Away =   $array[$i]['AWAY'];

}
} else {
    echo "0 results";
}
$conn->close();
?>  

第二个php文件 Firsthalfprediction.php

<?php
include 'filtre1_danimarka.php';
include 'tableNameDanimarka.php';
include 'connectionDatabase.php';



    $FirstHalfHome=0;
    $FirstHalfDraw=0;
    $FirstHalfAway=0;


    $sql = "SELECT * FROM $tableName where B = '$B' AND E = '$E' AND F = '$F' AND O ='$O' ";
    $result = $conn->query($sql);
    if ($result->num_rows > 0) {
    $rowcount=mysqli_num_rows($result);
        // output data of each row 
        while($row = $result->fetch_assoc()) {

    if($row['Q'] == 1){
    $FirstHalfHome++;
    }
    elseif($row['Q'] == 0){
    $FirstHalfDraw++;
    }else{
    $FirstHalfAway++;
    }



        }


    $FirstHalfHomePrediction = round(($FirstHalfHome/$rowcount )*100);
    $FirstHalfDrawPrediction = round(($FirstHalfDraw/$rowcount )*100);
    $FirstHalfAwayPrediction = round(($FirstHalfAway/$rowcount )*100);


    } else {
        echo "0 results";
    }
    $conn->close();
    ?>

您正在每个循环迭代中覆盖变量。您应该填充一个新数组，并使用此数组输出数据

请阅读我在您的代码中的注释，我不能向您保证，没有错误，因为我无法测试它，但这应该会让您了解您需要什么，请先尝试自己修复错误，如果您不能这样做，请在此处评论以寻求帮助

非常感谢马文·菲舍尔。它工作得很好。
