note 76423 added to language.types.array

Another note on unquoted array indices. Because it is first interpreted as a constant, it must obey the naming convention of constants. i.e. a letter or underscore followed by optional letter, digit and/or underscore characters. Therefore while the following array declaration is legal: $a = array('1st'=>'First','2nd'=>'Second'); Trying to access either array item as follows causes an error: $first = "$a[1st]"; $second = "$a[2nd]"; ---- Server IP: 212.108.64.191 Probable Submitter: 84.203.112.14 ---- Manual Page -- http://www.php.net/manual/en/language.types.array.php Edit -- https://master.php.net/note/edit/76423 Del: integrated -- https://master.php.net/note/delete/76423/integrated Del: useless -- https://master.php.net/note/delete/76423/useless Del: bad code -- https://master.php.net/note/delete/76423/bad+code Del: spam -- https://master.php.net/note/delete/76423/spam Del: non-english -- https://master.php.net/note/delete/76423/non-english Del: in docs -- https://master.php.net/note/delete/76423/in+docs Del: other reasons-- https://master.php.net/note/delete/76423 Reject -- https://master.php.net/note/reject/76423 Search -- https://master.php.net/manage/user-notes.php
