note 73585 added to function.unserialize

When trying to serialize or unserialize recursive arrays or otherwise linked data you might find the undocumented R data type quite useful. If you want a array like the one produced with <? $a = array(); $a[0] =& $a; ?> serialized you can store it using a string simular to this one: <? $a = unserialize("a:1:{i:0;R:1;}"); ?> Both sources will make $a hold an array that self-references itself in index 0. The argument for R is the index of the created sub-variable of the serialize-string beginning with 1. ---- Server IP: 217.13.201.10 Probable Submitter: 217.93.237.219 ---- Manual Page -- http://www.php.net/manual/en/function.unserialize.php Edit -- https://master.php.net/note/edit/73585 Del: integrated -- https://master.php.net/note/delete/73585/integrated Del: useless -- https://master.php.net/note/delete/73585/useless Del: bad code -- https://master.php.net/note/delete/73585/bad+code Del: spam -- https://master.php.net/note/delete/73585/spam Del: non-english -- https://master.php.net/note/delete/73585/non-english Del: in docs -- https://master.php.net/note/delete/73585/in+docs Del: other reasons-- https://master.php.net/note/delete/73585 Reject -- https://master.php.net/note/reject/73585 Search -- https://master.php.net/manage/user-notes.php
