Question

我有以下数组名为investmentprogramscriteria和companyInvestmentProfil：

Array
(
[0] => Array
    (
        [criteriaID] => 55
        [criteriaIsMatchedIf] => 11, 12, 13
    )

[1] => Array
    (
        [criteriaID] => 54
        [criteriaIsMatchedIf] => 1
    )

[2] => Array
    (
        [criteriaID] => 52
        [criteriaIsMatchedIf] => 1
    )

)


Array
(
[0] => Array
    (
        [criteriaID] => 52
        [investmentprofileCriteriaAnswer] => 1
    )

[1] => Array
    (
        [criteriaID] => 54
        [investmentprofileCriteriaAnswer] => 1
    )

[2] => Array
    (
        [criteriaID] => 58
        [investmentprofileCriteriaAnswer] => 0
    )

[3] => Array
    (
        [criteriaID] => 59
        [investmentprofileCriteriaAnswer] => 1
    )

[4] => Array
    (
        [criteriaID] => 55
        [investmentprofileCriteriaAnswer] => 1
    )

)

我试图找出第一个数组（investmentprogramscriteria）中的criteriaID的值是否存在于第二个数组（companyInvestmentProfil）中，并且IF第一个数组中的key criteriaIsMatchedIf的值是否等于键的值来自第二个阵列的investmentprofileCriteriaAnswer。

我当前的php代码此时返回错误的结果：

if (array_intersect($investmentprogramscriteria,$companyInvestmentProfil))     {
    echo "Match";
 } else {
    echo "Not match";
 }

Answer 1

array_column()可以提取指示为单个维度的列，并按指示的下一列对其进行索引。对两个数组执行此操作，然后使用array_intersect_assoc()检查键和值：

if(array_intersect_assoc(
array_column($investmentprogramscriteria, 'criteriaIsMatchedIf', 'criteriaID'),
array_column($companyInvestmentProfil, 'investmentprofileCriteriaAnswer', 'criteriaID'))) {
    echo "Match";
} else {
    echo "No Match";
}

{p <1}}需要

PHP＆gt; = 5.5.0或使用PHP Implementation of array_column()。

Answer 2

您可以使用array_map尝试代码：

$elements1 = array();
foreach($investmentprogramscriteria as $item) {
    $elements1[] = $item['criteriaID'] . $item['criteriaIsMatchedIf'];
}
$elements2 = array();
foreach($companyInvestmentProfil as $item) {
    $elements2[] = $item['criteriaID'] . $item['criteriaIsMatchedIf'];
}

if (array_intersect($elements1, $elements2))     {
    echo "Match";
} else {
    echo "Not match";
}

比较php中2个数组中的值 - array_intersect不起作用
