note 57460 added to function.var-dump

var_dump prefixes the variable type with & if the variable has more than one reference. This is only true for variables that are part of an array, not for scalar types. Example: <?php $a['foo'] = 'other'; $a['bar'] = 'i_have_ref'; $b =& $a['bar']; var_dump($a); var_dump($b); ?> Result: array(2) { ["foo"]=> string(5) "other" ["bar"]=> &string(10) "i_have_ref" } string(10) "i_have_ref" ---- Manual Page -- http://www.php.net/manual/en/function.var-dump.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57460 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57460&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57460&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57460&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57460&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57460&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57460&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57460&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57460&report=yes Search -- http://master.php.net/manage/user-notes.php
