If condition to check value of multiple column array php - php

Question

I am trying to get value of is_activated column key. But can not get the exact value. Have tried array_search()
Review the array
Need to check value of all is_activated key whether it's value is 1 or not.
Array
(
[0] => Array
(
[first_name] => Array
(
[0] => john
)
[is_activated] => Array
(
[0] => 0
)
)
[1] => Array
(
[first_name] => Array
(
[0] => mark
)
[is_activated] => Array
(
[0] => 1
)
)
[2] => Array
(
[first_name] => Array
(
[0] => pretik
)
[is_activated] => Array
(
[0] => 0
)
)
)
I have tried this below solution but can can not get result.
$is_user_activated = array_search(1,array_column($activity,'is_activated'));
if($is_user_activated == 1) { echo 'yes'; }
else { echo 'no'; }

Answer 1

I think you want to be doing this in a loop rather than using array_search. Use a foreach() to get your desired result:
foreach($yourArray as $item) {
if($item['is_activated'][0] == 1) {
echo 'yes';
} else {
echo 'no';
}
}

You can use the array_filter() for such tasks, it allows to use a callback filter function:
<?php
$data = [
[
'first_name' => ['john'] ,
'is_activated' => [0]
],
[
'first_name' => ['mark'],
'is_activated' => [1]
],
[
'first_name' => ['pretik'],
'is_activated' => [0]
]
];
$matches = array_filter($data, function($entry) {
return in_array(1, $entry['is_activated']);
});
var_dump($matches);
The output of that is:
array(1) {
[1]=>
array(2) {
["first_name"]=>
array(1) {
[0]=>
string(4) "mark"
}
["is_activated"]=>
array(1) {
[0]=>
int(1)
}
}
}
Reason why that is a bit awkward is that your initial data has a very strange structure: the values of the elements are arrays themselves holding the actual values instead of scalar values themselves. That makes searching more complex than in "normal" situations. So take a good look if maybe you can fix that strange structure instead to be able to use an easier search approach.

You can get the activated users via array_filter:
$activated = array_filter($users, function($record) {
return reset($record['is_activated']) == 1;
});
This will only keep users who are activated, you can then simply count the array to see if you have any activated users:
echo count($activated) ? 'yes' : 'no';
