note 82150 added to language.operators.increment

In reply to Anonymous : What is strange is that you didn't get an error : ++$var is an expression and can't therefore not be referenced. Now, if you suppose an implicit assignment to an invisible variable, your code becomes : <?php $var = 1; $plus_plus_var = ++$var; change($plus_plus_var); echo "var=$var"; ?> Written as such, change clearly acts on $plus_plus_var, not on $var. So PHP5 got right, and it's not a "strange behaviour", it's only a solved bug. Anyway, it's always a bad idea to pass anything other than a variable as a by-reference parameter... ---- Server IP: 217.174.223.124 Probable Submitter: 212.99.15.251 ---- Manual Page -- http://www.php.net/manual/en/language.operators.increment.php Edit -- https://master.php.net/note/edit/82150 Del: integrated -- https://master.php.net/note/delete/82150/integrated Del: useless -- https://master.php.net/note/delete/82150/useless Del: bad code -- https://master.php.net/note/delete/82150/bad+code Del: spam -- https://master.php.net/note/delete/82150/spam Del: non-english -- https://master.php.net/note/delete/82150/non-english Del: in docs -- https://master.php.net/note/delete/82150/in+docs Del: other reasons-- https://master.php.net/note/delete/82150 Reject -- https://master.php.net/note/reject/82150 Search -- https://master.php.net/manage/user-notes.php
