note 84502 added to language.references

You can make references like pointers. Example: <?php $a=6; $b=array(&$a); // $b is a pointer to $a $c=array(&$b); // $c is a pointer to $b $d=7; $c[0][0]=9; // $a is 9 $c[0]=array(&$d); // $b is a pointer to $d $c[0][0]=4; // $d is 4 $b=array(&$a); // $b is a pointer to $a again echo $a.$b[0].$c[0][0].$d; // outputs 9994 ?> These kind of pointers may even be passed to functions or returned from functions, copied and stored in multiple arrays/variables/objects, etc. ---- Server IP: 66.207.199.35 Probable Submitter: 24.207.61.48 ---- Manual Page -- http://www.php.net/manual/en/language.references.php Edit -- https://master.php.net/note/edit/84502 Del: integrated -- https://master.php.net/note/delete/84502/integrated Del: useless -- https://master.php.net/note/delete/84502/useless Del: bad code -- https://master.php.net/note/delete/84502/bad+code Del: spam -- https://master.php.net/note/delete/84502/spam Del: non-english -- https://master.php.net/note/delete/84502/non-english Del: in docs -- https://master.php.net/note/delete/84502/in+docs Del: other reasons-- https://master.php.net/note/delete/84502 Reject -- https://master.php.net/note/reject/84502 Search -- https://master.php.net/manage/user-notes.php
