Question

我不知道该怎么做，但如果可以做到，任何人都可以帮助我。基本上我的表中有3列：

ID Set   Result Case  
1  Set1  PASS   101  
2  Set2  FAIL   102  
3  Set2  FAIL   101  
4  Set1  FAIL   101  
5  Set1  PASS   104  

$set =  $row['Set'];

我想要实现的是这些Set，将其关联的Result和Case存储在数组中。

Answer 1

$arr = array();

foreach ($records as $key => $value)
{
    $arr[$key]['Result'] = $value['Result'];
    $arr[$key]['Case'] = $value['Case'];
}

echo '<pre>';
print_r($arr);
echo '</pre>';

根据你的评论：

foreach ($records as $key => $value)
{
    $arr[$key][$value['Result']] = $value['Case'];
}

根据您最近的评论：

foreach ($records as $key => $value)
{
    $arr[$value['Set']][$value['Result']] = $value['Case'];
}

Answer 2

看完评论后，我以为我会对它进行抨击。

首先：除非您要在$array[Set2][{result}]中检查重复的{结果}键，否则您要求的内容将无效，如果您的评论中有重复项，则会将其缩小，我不知道为什么你这样做。这将是令人困惑的，并且让我觉得荒谬。即：

$arr[Set2][FAIL]与$arr[Set2][fail]

如果您按照上面[Alix Axel的第三个代码块中所示]执行此操作，您将执行以下操作：

$arr[Set2][FAIL] = 102然后用$arr[Set2][FAIL] = 101覆盖该数组索引值，导致您丢失数据。

换句话说，你使用“set”和“result”的组合作为“组合键”可以说，你不能这样做，因为组合不是唯一的（Set2 FAIL，Set2 FAIL）。我知道这是一个令人烦恼的答案，但你应该看看你在做什么以及为什么，因为我有预感你会采取错误的方式。你可能想要一个像：

这样的数组

Array
(  
    [Set1] => Array
    (  
            [101] => 'FAIL'  
            [102] => 'PASS'  
    )

    [Set2] => Array
    (  
            [101] => 'FAIL'  
            [102] => 'FAIL'  
    )
)

或其他东西，但即使这样它也不会起作用，因为你有一些Set / Case对传递和失败。因此，你在这里唯一能做的就是使用“id”作为索引：

Array
(  
    [1] => Array
    (  
            [Set] => 'Set1'  
            [Result] => 'PASS'  
            [Case] => '101'  
    )
    [2] => Array
    (  
            [Set] => 'Set1'  
            [Result] => 'FAIL'  
            [Case] => '101'  
    )
)

但我甚至不能告诉你如何做到这一点，因为你没有告诉我们你的查询结果数组是如何构建的！所以步骤1）请print_r或var_dump查询结果。

// assuming
$myArray = array();
$result = mysql_query("SELECT * FROM table ORDER BY Set ASC");
while ($rows = mysql_fetch_assoc($result)) {
  for ($i = 0; $i <= count($rows); $i++) {
    $myArray[$rows['ID']]['Set'] = $rows['Set'];
    $myArray[$rows['ID']]['Result'] = $rows['Result'];
    $myArray[$rows['ID']]['Case'] = $rows['Case'];
}

// output
Array
(
    [1] => Array
    (
        [Set] => 'Set1'
        [Result] => 'PASS'
        [Case] => '101'
    )
    [2] => Array
    (
        [Set] => 'Set1'
        [Result] => 'FAIL'
        [Case] => '101'
    )
    [3] => Array
    (
        [Set] => 'Set1'
        [Result] => 'PASS'
        [Case] => '104'
    )
    [4] => Array
    (
        [Set] => 'Set2'
        [Result] => 'FAIL'
        [Case] => '102'
    )
    [5] => Array
    (
        [Set] => 'Set2'
        [Result] => 'FAIL'
        [Case] => '101'
    )
)

Answer 4

Ages之前编写了一个处理短查询的函数，它返回MySQL查询结果的多维数组（命名为tablename）。希望这可以节省处理简单和简短的MySQL查询的时间：

<?php
/*
FUNCTION: db2array($tablename, $condition)

Which simply makes a query: SELECT * FROM $tablename WHERE $condition
and returns multidimensional array()* named as 
DB_table_name with keys named as tables_cell_name followed by row_number:

*Returns multidimensional array: $my_table[cell_name][row_number] 

Example 1:  
db2array("my_table", "cell_name = 'A' ORDER BY id LIMIT 1")
where "my_table" is DB tablename and $condition is all the rest 
what comes after MySQL's WHERE;

Example 2:
db2array("my_table"); 

Returns: $my_table[];
To see results, go for print_r($my_table[]);

*/

function db2array($tablename, $condition){

    global $$tablename;

    //if $condition is NULL set it to 1=1
    $condition = ($condition)?$condition:"1=1";

    $query = mysql_query("
    SELECT * FROM $tablename WHERE $condition
    ") or die(mysql_error()); 

    // COUNTING FIELDS AND ROWS
    $f_to = mysql_num_fields($query);
    $n_to = mysql_num_rows($query);

    // EXIT IF NO RESULTS
    if (!mysql_num_rows($query)) return false;


    // PUSHING ALL CELL NAMES TO $cellname ARRAY
    for ($f=0; $f<=$f_to-1; $f++){
        $cellname[$f] = mysql_field_name($query, $f);
    }

    //  GENERATING OUTPUT ARRAY
    for ($n=0; $n<=$n_to-1; $n++){
        foreach ($cellname as $val){
            $result[$val][$n] = mysql_result($query, $n, $val);
        }
    }

    $$tablename = $result;
    return $$tablename;

}
?>
