note 111523 added to language.types.integer

A leading zero in a numeric literal means "this is octal". But don't be confused: a leading zero in a string does not. Thus: $x = 0123; // 83 $y = "0123" + 0 // 123 ---- Server IP: 69.147.83.199 Probable Submitter: 87.194.171.29 ---- Manual Page -- http://php.net/manual/en/language.types.integer.php Edit -- https://master.php.net/note/edit/111523 Del: integrated -- https://master.php.net/note/delete/111523/integrated Del: useless -- https://master.php.net/note/delete/111523/useless Del: bad code -- https://master.php.net/note/delete/111523/bad+code Del: spam -- https://master.php.net/note/delete/111523/spam Del: non-english -- https://master.php.net/note/delete/111523/non-english Del: in docs -- https://master.php.net/note/delete/111523/in+docs Del: other reasons-- https://master.php.net/note/delete/111523 Reject -- https://master.php.net/note/reject/111523 Search -- https://master.php.net/manage/user-notes.php
