array_change_key_case
Posted on March 28th, 2009 No commentsThis function changes all keys in an array by returning an array with all keys from argument lowercased or uppercased. Numbered indices are left as is.
PHP
$input_array = array('FirSt' => 1, 'SecOnd' => 4); print_r( array_change_key_case($input_array, CASE_UPPER) ); // => array('FIRST' => 1, 'SECOND' => 4);
To replicate this functionality in Ruby, we need to use a Hash object, since arrays in Ruby don’t use associative key/value pairs.
Ruby
hash = {'FirSt' => 1, 'SecOnd' => 4} result = hash.inject({}) do |hash, keys| hash[keys[0].upcase] = keys[1] hash end p result # => { 'FIRST' => 1, 'SECOND' => 4 }
