Note Submitter: Jason ---- <?php /* Another version of subArr() function by simone dot carletti at unimc dot it: written for http://www.hendersonpoolservice.info */ //{{{ array_select() /** * Choose array element with given keys * * @param Array $arr * @param Array $keys Keys/indexes of elements to choose * @return Array Array with elements being references to the elements od original array with chosen indexes. */ function &array_select($arr, $keys) { $res = array(); foreach ($keys as $key) { if (array_key_exists($key, $arr)) { $res[$key] =& $arr[$key]; } } return $res; } // end: array_select() }}} /* In my opinion it should be faster than subArr(). Another difference from subArr() is that elements of returned array are references to the same variables as elements of original array (this can be easily changed) */ ?>
