array_keys
Posted on February 24th, 2010 No commentsThe array_keys() function in PHP takes an array as it’s argument and returns all the keys in that array (as a numeric array).
PHP
$array = array('go' => 'green', 'stop' => 'red'); var_dump( array_keys($array) ); /* Array ( [0] => go [1] => stop ) */
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
array = { :go => 'green', :stop => 'red' }; puts array.keys; # => [:go, :stop]

array_product
Posted on February 17th, 2010 No commentsThe array_product() PHP function returns the product of all values in an array. In other words, it multiplies all values in the array together, and returns the result as a number.
PHP
$a = array('1', '2', '3'); $product_total = array_product($a); echo $product_total; // => 6
Ruby
a = [ "1", "2", "3" ]; product_total = a.inject {|product, element| product * element } puts product_total; # => 6

array_rand
Posted on February 16th, 2010 No commentsThe array_rand() function in PHP randomly selects one or more elements from an array.
PHP
$users = array('john', 'jane', 'tim', 'alex'); $lucky_winner = array_rand($users); echo $lucky_winner; // alex
Ruby
users = [ 'john', 'jane', 'tim', 'alex' ]; lucky_winner = users[rand(users.length)]; puts lucky_winner; # => alex
