note 114620 added to language.references

Simply put, here's an example of what referencing IS: <?php $foo = 5; $bar = &$foo; $bar++; echo $foo; ?> The above example will output the value 6, because $bar references the value of $foo, therefore, when changing $bar's value, you also change $foo's value too. ---- Server IP: 72.52.91.14 Probable Submitter: 89.137.200.28 ---- Manual Page -- http://php.net/manual/en/language.references.php Edit -- https://master.php.net/note/edit/114620 Del: integrated -- https://master.php.net/note/delete/114620/integrated Del: useless -- https://master.php.net/note/delete/114620/useless Del: bad code -- https://master.php.net/note/delete/114620/bad+code Del: spam -- https://master.php.net/note/delete/114620/spam Del: non-english -- https://master.php.net/note/delete/114620/non-english Del: in docs -- https://master.php.net/note/delete/114620/in+docs Del: other reasons-- https://master.php.net/note/delete/114620 Reject -- https://master.php.net/note/reject/114620 Search -- https://master.php.net/manage/user-notes.php
