note 112289 added to language.types.array

Note that array value buckets are reference-safe, even through serialization. $x='initial'; $test=array('A'=>&$x,'B'=>&$x); $test=unserialize(serialize($test)); $test['A']='changed'; echo $test['B']; // Outputs "changed" This can be useful in some cases, for example saving RAM within complex structures. ---- Server IP: 94.76.225.145 Probable Submitter: 188.64.38.59 ---- Manual Page -- http://php.net/manual/en/language.types.array.php Edit -- https://master.php.net/note/edit/112289 Del: integrated -- https://master.php.net/note/delete/112289/integrated Del: useless -- https://master.php.net/note/delete/112289/useless Del: bad code -- https://master.php.net/note/delete/112289/bad+code Del: spam -- https://master.php.net/note/delete/112289/spam Del: non-english -- https://master.php.net/note/delete/112289/non-english Del: in docs -- https://master.php.net/note/delete/112289/in+docs Del: other reasons-- https://master.php.net/note/delete/112289 Reject -- https://master.php.net/note/reject/112289 Search -- https://master.php.net/manage/user-notes.php
