array_unique
Posted on October 10th, 2009 No commentsThe array_unique() function in PHP takes an array and filters our any duplicates values, returning the array with only unique values present.
PHP
$elements = array('php', 'ruby', 'perl', 'php'); array_unique($elements); print_r($elements); /* Array ( [0] => php [1] => ruby [2] => perl ) */
Ruby
elements = [ "php", "ruby", "perl", "php" ]; puts elements.uniq; # => ["php", "ruby", "perl"]
