Find value anywhere in the arrays, output content - php

Question

I have the array $conversion[$cohort_check] which is outputting the following:
Array
(
[0] => Array
(
[order_id] => 62056
[order_date] => 21-01
[total] => 5.5
[cumulative] => 0
[order_type] => one_time
)
[1] => Array
(
[order_id] => 52937
[order_date] => 21-02
[total] => 5.5
[cumulative] => 0
[order_type] => one_time
)
[2] => Array
(
[order_id] => 45849
[order_date] => 21-03
[total] => 7.89
[cumulative] => 0
[order_type] => parent
)
[3] => Array
(
[order_id] => 228
[order_date] => 21-10
[total] => 5.23
[cumulative] => 0
[order_type] => parent
)
)
How can I check if the value of order_type is parent exists anywhere within it?
I tried the following but don't think I'm quite hitting the right place.
if(in_array("parent", $conversion[$cohort_check])){
echo "subscribed!";
}
Is it then possible to grab the value of order_date for the first parent order it gets?

Answer 1

you do not need to loop over the array. PHP has the https://www.php.net/array_search, which does exactly what you need:
If you want just one result:
array_search('parent', array_column($array, 'order_type'));
For multiple results
$keys = array_keys(array_column($array, 'order_type'), 'parent');

Answer 2

$x = array(
array(
'order_id' => '62056',
'order_date' => '21-01',
'total' => '5.5',
'cumulative' => '0',
'order_type' => 'one_time'
),
array(
'order_id' => '62056',
'order_date' => '21-01',
'total' => '5.5',
'cumulative' => '0',
'order_type' => 'one_time'
),
array(
'order_id' => '52937',
'order_date' => '21-02',
'total' => '5.5',
'cumulative' => '0',
'order_type' => 'parent'
),
);
simply use foreach loop and then apply your condition on particular key
foreach ($x as $key => $xx) {
if($xx["order_type"] == "parent" ){
echo "Subscribed";
}
}

Answer 3

This will loop the array and echo the order_id that has order_type as parent (Subscribed).
$array = array(
array(
'order_id' => 1589,
'order_type' => 'one_time'
),
array(
'order_id' => 1579,
'order_type' => 'parent'
),
array(
'order_id' => 1289,
'order_type' => 'one_time'
),
array(
'order_id' => 2589,
'order_type' => 'parent'
),
array(
'order_id' => 1584,
'order_type' => 'one_time'
),
array(
'order_id' => 8589,
'order_type' => 'one_time'
),
);
foreach ($array as $value) {
if ($value['order_type'] === 'parent') {
echo 'Order: ' . $value['order_id'] . ': Subscribed' . '<br>';
}
}
// Output
Order: 1579: Subscribed
Order: 2589: Subscribed
EDIT:
There is another answer with array_keys(array_column($array, 'order_type'), 'parent') this indeed works fine but you're still going to have to then process that array to get some meaningful information like the order_id. Assuming that is ultimately what you're wanting (To see what order is subscribed).
