Question

我有一些数据来自平面数组中的mysql查询：

  0 => Array 
    indcode => "A00"
    indlabel => "Code label text"
    description => "More explanations"
  1 => Array 
    indcode => "NA0"
    indlabel => "Un-classified A"
    description => "Un-classified A"
  2 => Array (3)
    indcode => "A01"
    indlabel => "Code Label text"
    description => "More explanations"
  3 => Array (3)
    indcode => "A02"
    indlabel => "Code label text"
    description => "More explanations"

我想以这种方式嵌套：

  A00 => Array 
    indlabel => "Code label text"
    description => "More explanations"
  NA0 => Array 
    indlabel => "Un-classified A"
    description => "Un-classified A"
  A01 => Array 
    indlabel => "Code Label text"
    description => "More explanations"
  A02 => Array
    indlabel => "Code label text"
    description => "More explanations"

所以在我的CMS中我发现使用了一个非常简洁的代码来进行嵌套：

foreach ($dimsDesc as $desc) {
$descriptions[$desc['indcode']][$desc['indlabel']] = $desc['description'];
}

这有效，但我没有找到如何将indlabel和描述保持在同一级别（=等号的另一侧）。

此外，如果您有其他一些示例的链接或此构造的良好参考，我将不胜感激，因为我将使用它来构建动态报告...而现在PDO查询有点不在我的达到。我还使用array_column()和NULL一起工作，但我有更复杂的数据结构传入......

Answer 1

试试这个，

<?php
foreach ($dimsDesc as $desc) {
    $descriptions[$desc['indcode']] = array( 
        'indlabel' => $desc['indlabel'], 
        'description' => $desc['description']
    );
}
?>

你几乎就在那里，只需按照以下方式更改foreach循环，

foreach ($dimsDesc as $desc) {
    $descriptions[$desc['indcode']]['indlabel'] = $desc['indlabel'];
    $descriptions[$desc['indcode']]['description'] = $desc['description'];
}

或

foreach ($dimsDesc as $desc) { $descriptions[$desc['indcode']] = array('indlabel' => $desc['indlabel'], 'description' => $desc['description']); }
