note 23860 added to language.types.array

When using array inside double-quoted string key should be single-quoted only if you use curly braces around variable like this: $array = array('key' => 'value'); incorrect syntax: echo "value = $array['key'] \n"; echo "value = {$array[key]} \n"; first line compiler won't even compile on second line compiler will consider "key" as contant and will show warning if error_reporting is E_ALL correct syntax: echo "value = $array[key] \n"; echo "value = {$array['key']} \n"; on first line: no curly braces - no quotes second line: use curly braces - should use quotes -- http://www.php.net/manual/en/language.types.array.php http://master.php.net/manage/user-notes.php?action=edit+23860 http://master.php.net/manage/user-notes.php?action=delete+23860 http://master.php.net/manage/user-notes.php?action=reject+23860
