Sometimes, you need to get minimum key value of your array but you try to get with loop and any function etc, but in bellow example you can see we can get smallest key value from our php array by using min() and array_keys(). So, let’s try to use in your code this way:
Example:
$myArray = ['2'=>'Hey','4'=>'Hello','1'=>'Hi','3'=>'GH'];
$new_key = min(array_keys($myArray));
$new_val = $myArray[$new_key];
print_r($new_val);
