check if value exists in multidimensional array and find index - php

Question

I have an multidimensional array like this:
$downloadArray = [
"downloads1" => ["downloadnaam" => "fdgssgsfg"],
"downloads2" => ["downloadnaam" => "eyetyy"],
];
I need to check if the value eyetyy exists in this array under the key downloadnaam
Then I need to find the index of this value and remove it from the array.
The expected result:
$downloadArray = [
"downloads1" => ["downloadnaam" => "fdgssgsfg"]
];
I tried this:
$index = array_search($download->name, array_column($downloadArray, 'downloadnaam'));
if ($index !== null)
{
unset($downloadArray[$index]);
die("found index: " . $index);
}
$download->name contains 'eyetyy'
$downloadArray is my array
But it always dies and doesn't show any index on screen.
Can anyone help me?

Answer 1

Try in this way:
$downloadArray = [
"downloads1" => ["downloadnaam" => "fdgssgsfg"],
"downloads2" => ["downloadnaam" => "eyetyy"],
];
$filter = "eyetyy";
// Search for index
$index = array_search($filter, array_column($downloadArray, "downloadnaam"));
if ($index !== false) {
// Delete
array_splice($downloadArray, $index, 1);
}
print_r($downloadArray);
die();
Output:
Array
(
[downloads1] Array
(
[downloadnaam] fdgssgsfg
)
)

Answer 2

I got it working using this code
$downloadArray = array_filter($downloadArray, function ($item) use ($download) {
return $item['downloadnaam'] != $download->name;
});
This way I don't need to find the index first.

you can try this :
$downloadArray = [
"downloads1" => ["downloadnaam" => "fdgssgsfg"],
"downloads2" => ["downloadnaam" => "eyetyy"],
];
foreach ($downloadArray as $subKey => $subArray) {
if (\in_array($subArray['downloadnaam'], ['eyetyy'], true)) {
unset($downloadArray[$subKey]);
}
}
var_dump($downloadArray);
