current

  • Ruby has no internal pointer in array objects like PHP. Because of this, there is no direct equivalent to PHP’s current function.

    Sometimes current is used to grab the first value of an array. We can do this in Ruby using the Array#first method.

    PHP

    $fruit = array('apple', 'orange');
$result = current($fruit);
var_export($result);
// => 'apple'

    Ruby

    fruit = ["apple", "orange"]
result = fruit.first
# => "apple"

    The first method does not work for associative key/value hashes in Ruby since hashes are unordered collections.
