note 89684 added to function.array-merge-recursive

<?php /** * array_merge_recursive does indeed merge arrays, but it converts values with duplicate * keys to arrays rather than overwriting the value in the first array with the duplicate * value in the second array, as array_merge does. I.e., with array_merge_recursive, * this happens (documented behavior): * * array_merge_recursive(array('key' => 'org value'), array('key' => 'new value')); * => array('key' => array('org value', 'new value')); * * array_merge_recursive_distinct does not change the datatypes of the values in the arrays. * Matching keys' values in the second array overwrite those in the first array, as is the * case with array_merge, i.e.: * * array_merge_recursive_distinct(array('key' => 'org value'), array('key' => 'new value')); * => array('key' => array('new value')); * * Parameters are passed by reference, though only for performance reasons. They're not * altered by this function. * * @param array $array1 * @param mixed $array2 * @return array * @author daniel@danielsmedegaardbuus.dk */ function &array_merge_recursive_distinct(array &$array1, &$array2 = null) { $merged = $array1; if (is_array($array2)) foreach ($array2 as $key => $val) if (is_array($array2[$key])) $merged[$key] = is_array($merged[$key]) ? array_merge_recursive_distinct($merged[$key], $array2[$key]) : $array2[$key]; else $merged[$key] = $val; return $merged; } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 62.243.22.18 ---- Manual Page -- http://www.php.net/manual/en/function.array-merge-recursive.php Edit -- https://master.php.net/note/edit/89684 Del: integrated -- https://master.php.net/note/delete/89684/integrated Del: useless -- https://master.php.net/note/delete/89684/useless Del: bad code -- https://master.php.net/note/delete/89684/bad+code Del: spam -- https://master.php.net/note/delete/89684/spam Del: non-english -- https://master.php.net/note/delete/89684/non-english Del: in docs -- https://master.php.net/note/delete/89684/in+docs Del: other reasons-- https://master.php.net/note/delete/89684 Reject -- https://master.php.net/note/reject/89684 Search -- https://master.php.net/manage/user-notes.php
