In what scenarios would using array_combine() be more efficient than other methods for accessing multiple keys in PHP?

When you need to combine two arrays into a single associative array where one array contains keys and the other contains values, using array_combine() is more efficient than manually looping through the arrays to create the associative array. This function simplifies the process and can be more performant when dealing with large datasets. 

// Example using array_combine()
$keys = ['name', 'age', 'city'];
$values = ['John', 30, 'New York'];

$combinedArray = array_combine($keys, $values);

print_r($combinedArray);
