PHP檢查另一個數組中是否存在一個數組中的值

Question

我的項目中有兩個數組。 它們是“ $ results”和“ $ hits_navn”。

$ hits_navn看起來像這樣：

Array ( [0] => HOPLAND ROGER [1] => TRACKSON AS ) 

雖然$ results看起來像這樣：

array(4) {
  [0]=>
  array(5) {
    ["_index"]=>
    string(19) "aksjeregisteret2017"
    ["_type"]=>

我想做的是檢查$ hits_navn內部的值是否存在於$ results的一個或多個索引（[0]或[1]等）中。 如果它們確實存在（又名匹配），我想在頁面的html表中輸入它們。

我在獲取它時遇到問題。 我試過一段時間內使用if（array_key_exists），但這樣做沒有任何結果。 我嘗試添加一個foreach（$ results作為$ results），但這給了我以下錯誤：

Warning: array_key_exists() expects parameter 2 to be array, string given in /var/www/html/altinn/index.php on line 195

四次。

我顯然做錯了什么。 有適當的方法來做這樣的事情嗎？

我正在使用的代碼：

$tal = 0;
while ($tal < count($hits_navn)) {
    foreach ($results as $results) {
        if (array_key_exists($hits_navn[$tal], $results['_source'])) {

        //Creates the first row of the table.
        if (!isset($it)) {
        echo "<div class='container'>
        <div class='table-responsive'>
        <table class='table table-hover'>
        <thead class='thead-light'>
        <tr>
        <th scope='col'>Orgnr</th>
        <th scope='col'>Selskap</th>
        <th scope='col'>Navn Aksjoner</th>
        <th scope='col'>Fodselar/Orgnr</th>
        <th scope='col'>Antall Aksjer</th>
        <th scope='col'>Antall Aksjer Selskap</th>
        </tr>
        </thead>";
        $it = 1;
        }

        //Creates all other rows in the table.
        <tr>
        <td><?php echo $results['_source']['Orgnr'] ?></td>
        <td><?php echo $results['_source']['Selskap'] ?></td>
        <td><?php echo $results['_source']['Navn Aksjoner'] ?></td>
        <td><?php echo $results['_source']['Fodselar/Orgnr'] ?></td>
        <td><?php echo $results['_source']['Antall Aksjer'] ?></td>
        <td><?php echo $results['_source']['Antall Aksjer Selskap'] ?></td>
        </tr>
        <?php
        }
    }
    $tal++;
} 

Answer 1

我認為您可以使用array_intersect獲得想要的結果。

http://php.net/manual/zh/function.array-intersect.php

例：

<?php
$array1 = array("a" => "green", "red", "blue");
$array2 = array("b" => "green", "yellow", "red");
$result = array_intersect($array1, $array2);
print_r($result);

如您所見，這完全忽略了array key ，只尋找值。

結果：

Array
(
    [a] => green
    [0] => red
)

嘗試在_source子數組上使用它。

Answer 2

array_key_exists（）是在數組的鍵中搜索，而不是在值中搜索。

您可以在這里做什么：

$tableHeader = "[header]"; // put the header of the table here
$tableContent = "";

foreach ($results as $result) {
    foreach ($hits_navn as $navn) {
        // found in results array
        if (in_array($navn, $result) or in_array($navn, $result['source')) {
            $tableContent .= "[row content]"; // create a row for the table
        }
    }
}

$table = $tableHeader . $tableContent;
