PHP检查另一个数组中是否存在一个数组中的值

Question

I've two arrays in my project. They are "$results" and "$hits_navn".

$hits_navn looks like this:

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

While $results looks like this:

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

What I'm trying to do is check if the values inside $hits_navn exists inside one or more of the indexes (the [0], or [1], etc) of $results. If they do exist (aka there is a match) I want to enter them into a html table on the page.

I'm having problem getting it. I've tried using if(array_key_exists) inside a while but doing that gives me no results. I've tried adding a foreach($results as $results) but this gives me the following errors:

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

Four times.

I'm obviously doing something very wrong. Is there a proper way to do something like this?

The code i'm working with:

$tal = 0;
while ($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

I think you could use array_intersect to get the result you're looking for.

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

Example:

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

As you can see this completely ignores the array key and just looks for the value.

Result:

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

Try using this on your _source sub array.

Answer 2

array_key_exists() is a search in the keys of the array, not in the values.

Here what you can do:

$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;
