note 69235 added to ref.array

Regarding the function of spam at madhermit dot net from January 9th 2006: That function only preserves the deepest keys and values. If you try to flatten an array with that function where the deepest instance of keys might be the same where as keys in the "key-path" are different, values will be overwritten. So here is a function that preserves the whole key-path and the keys of the flattened array will be string keys consisting of the key-path separated by $Separator. <?php // flatten multidimensional array to one dimension // preserves keys by generating a key for the flattened array which consists of the // key-path of the multidimensional array separated by $Separator // usage: array ArrayFlatten( array Array [, string Separator] ) function ArrayFlatten($Array,$Separator="_",$FlattenedKey='') { $FlattenedArray=Array(); foreach($Array as $Key => $Value) { if(is_Array($Value)) $FlattenedArray=Array_merge($FlattenedArray, ArrayFlatten($Value,$Separator, (strlen($FlattenedKey)>0 ?$FlattenedKey.$Separator :"").$Key) ); else $FlattenedArray[$FlattenedKey.$Separator.$Key]=$Value; } return $FlattenedArray; } ?> ---- Server IP: 66.163.161.117 Probable Submitter: 84.185.247.44 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/ref.array.php Edit -- https://master.php.net/note/edit/69235 Del: integrated -- https://master.php.net/note/delete/69235/integrated Del: useless -- https://master.php.net/note/delete/69235/useless Del: bad code -- https://master.php.net/note/delete/69235/bad+code Del: spam -- https://master.php.net/note/delete/69235/spam Del: non-english -- https://master.php.net/note/delete/69235/non-english Del: in docs -- https://master.php.net/note/delete/69235/in+docs Del: other reasons-- https://master.php.net/note/delete/69235 Reject -- https://master.php.net/note/reject/69235 Search -- https://master.php.net/manage/user-notes.php
