What is the significance of using in_array() to check for rights in PHP?

Using in_array() in PHP is significant for checking if a specific value exists within an array. This is commonly used when checking for user rights or permissions within an application. By using in_array(), we can easily determine if a user has a specific right without having to manually iterate through the array. 

// Example code snippet to check if a user has a specific right using in_array()

$userRights = ["read", "write", "delete"];

if (in_array("write", $userRights)) {
    echo "User has write permission";
} else {
    echo "User does not have write permission";
}
