More References Fun! <?php $a = 'This is a string'; $b = &$a; $c = &$b; $d = $b; echo 'c = '. $c .'<br />'; echo 'd = '. $d .'<br />'; $a = 'Changed a String'; echo '<br />'; echo 'c = '. $c .'<br />'; echo 'd = '. $d .'<br />'; unset($b); $b = 'Some other string'; $a = 'Changed a String Again'; echo '<br />'; echo 'c = '. $c .'<br />'; echo 'd = '. $d .'<br />'; ?> The output being: c = This is a string d = This is a string c = Changed a String d = This is a string c = Changed a String Again d = This is a string This basically means that references to references (why you would use this though is beyond me), doesn't make a reference of the reference variables reference (etc... if you know what I mean), but is basically a copy of the reference to the 'real' variable. ---- Manual Page -- http://www.php.net/manual/en/language.references.whatdo.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52835 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52835&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52835&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52835&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52835&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52835&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52835&report=yes Search -- http://master.php.net/manage/user-notes.php
