How can I get a random username from my first array, but the username selected shouldn't be in the "denied usernames Array" in PHP

Array of usernames

Array ( 

  [0] => stdClass Object ( [user_login] => emma88 ) 

  [1] => stdClass Object ( [user_login] => milli ) 

  [2] => stdClass Object ( [user_login] => [email protected] ) 

  [3] => stdClass Object ( [user_login] => shawn ) 

  [4] => stdClass Object ( [user_login] => shawnfao2 ) 

)

denied usernames Array: 

Array ( 

   [0] => Array ( [username] => emma88 ) 

   [1] => Array ( [username] => milli ) 

   [2] => Array ( [username] => [email protected] ) 

)

My Answer:
You can achieve this by first filtering out the denied usernames from the first array and then selecting a random username from the filtered array. Here's how you can do it:

php
// Array of usernames
$usernames = [
(object) ['user_login' => 'emma88'],
(object) ['user_login' => 'milli'],
(object) ['user_login' => 'test@example.com'],
(object) ['user_login' => 'shawn'],
(object) ['user_login' => 'shawnfao2']
];

// Denied usernames array
$deniedUsernames = [
['username' => 'emma88'],
['username' => 'milli'],
['username' => 'test@example.com']
];

// Filter out denied usernames
$filteredUsernames = array_filter($usernames, function($username) use ($deniedUsernames) {
foreach ($deniedUsernames as $denied) {
if ($username->user_login === $denied['username']) {
return false;
}
}
return true;
});

// Get a random username from the filtered array
$randomUsername = $filteredUsernames[array_rand($filteredUsernames)]->user_login;

echo $randomUsername;


This code will first filter out the denied usernames from the `$usernames` array and then select a random username from the filtered array.
