Are there any best practices or built-in PHP functions that can simplify the process of converting array keys to values without the need for additional queries or functions?

When converting array keys to values in PHP, one approach is to use the array_flip() function. This function exchanges all keys with their associated values in an array, effectively converting keys to values and vice versa. By using array_flip(), you can simplify the process without the need for additional queries or custom functions.

// Sample array with keys to be converted to values
$array = array('a' => 'apple', 'b' => 'banana', 'c' => 'cherry');

// Convert array keys to values
$array = array_flip($array);

// Output the modified array
print_r($array);
