note 118132 deleted from function.array-unique by crell

Note Submitter: tim at heuer dot nz ---- I created a function for doing array_unique with a custom in_array function. So, if elements are considered in the array passed to this function, the array returned won't include elements that are considered equal and only return the values from the first array that are not considered in the array: <?php function uniqueBy(array $array, callable $in_array_func) { $result = array(); foreach ($array as $key => $item) { if (!$in_array_func($item, $result)) { $result[$key] = $item; } } return $result; } ?> Example usage: <?php $in_array_func = function($item, $array) { $fromBower = function($item) { $result = substr($item, strpos($item, 'bower_components')); return $result; }; foreach ($array as $myItem) { if ($fromBower($item) == $fromBower($myItem)) { return true; } } return false; }; // ... $jss = uniqueBy($jss, $in_array_func); ?>
