// note: my previous post have one small error in call to array_key_exists() - posting again - please remove this comment and that note :-) <?php /* Another version of subArr() function by simone dot carletti at unimc dot it: */ //{{{ 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) */ ?> ---- Server IP: 195.136.184.34 Probable Submitter: 212.14.58.157 ---- Manual Page -- http://www.php.net/manual/en/ref.array.php Edit -- https://master.php.net/note/edit/72822 Del: integrated -- https://master.php.net/note/delete/72822/integrated Del: useless -- https://master.php.net/note/delete/72822/useless Del: bad code -- https://master.php.net/note/delete/72822/bad+code Del: spam -- https://master.php.net/note/delete/72822/spam Del: non-english -- https://master.php.net/note/delete/72822/non-english Del: in docs -- https://master.php.net/note/delete/72822/in+docs Del: other reasons-- https://master.php.net/note/delete/72822 Reject -- https://master.php.net/note/reject/72822 Search -- https://master.php.net/manage/user-notes.php
