In what scenarios would it be beneficial for PHP developers to preload names and use regular expressions for searching, and what considerations should be taken into account when making this decision?

When dealing with a large dataset of names that need to be searched frequently, it can be beneficial for PHP developers to preload the names into memory and use regular expressions for searching. This approach can improve search performance by avoiding repeated database queries and leveraging the power of regular expressions for flexible matching. 

// Preload names into an array
$names = ['Alice', 'Bob', 'Charlie', 'David', 'Eve'];

// Search using regular expression
$searchTerm = 'b';
$pattern = '/^' . $searchTerm . '/i'; // Case-insensitive match for names starting with the search term
$matches = preg_grep($pattern, $names);

// Output matched names
foreach ($matches as $match) {
    echo $match . "\n";
}
