如何在php中匹配两个不同的多维数组

Question

我有两个数组，我想匹配第二个数组

['Name']

值的

[Seltemgr]

值，如果

['Name']=>value == [Seltemgr]=>value

则

<input type="checkbox" checked="checked">

，否则未选中，是否可以匹配具有不同键的不同元素数量的两个多维数组。

Answer 1

$match = [];

foreach ($array1 as $k1=>$a1){
      foreach($array2 as $k2=>$a2){
                 if($a2['Seltemgr'] == $a1['Name']){
                         $match[] = array($k1,$k2);
                 }
       }
}

因此 $match 包含 Name 和 Seltemgr 匹配的每个数组的索引。并不是说这是执行此操作的最佳方法，但相交函数通常需要键来匹配。

Answer 2

我可能建议将

found

元素附加到第一个数组的每一行。 然后，您可以迭代该数组来根据需要打印标记并设计其样式。 一旦在进行迭代值检查时遇到最佳性能的真实评估，

array_any()

调用就会短路。 演示

var_export(
    array_map(
        fn($row) => $row
            + ['found' => array_any($selected, fn($selRow) => $row['Name'] == $selRow['Seltemgr'])],
        $checkboxes
    )
);
