note 62785 added to control-structures.foreach

To atroxodisse: This behaviour is normal. PHP arrays are associative arrays but, unlike Perl, with artificial order maintenance. Keys can be any scalar value except references; of course integers are scalars, so traditional integer-indexed arrays just work. {You can even have fractions in array indices, as long as you enclose the index in speech marks, such as $array["1.5"]! This is not unique to PHP, by the way, but existed by accident in some dialects of BASIC seen on 1980s-vintage home computers.} The foreach loop iterates over keys in chronological order of when they were added to the array, which is *not* necessarily the same as the sort order. The print_r() function uses the same iteration order. If you want to add elements to the beginning of an existing numeric array {or between existing elements -- either using fractional indices, or because you left gaps when populating the array} and have foreach iterate over them in order, then you will need to use ksort() on the array *first*. ---- Server IP: 66.163.161.117 Probable Submitter: 85.189.11.2 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- http://master.php.net/note/edit/62785 Del: integrated -- http://master.php.net/note/delete/62785/integrated Del: useless -- http://master.php.net/note/delete/62785/useless Del: bad code -- http://master.php.net/note/delete/62785/bad+code Del: spam -- http://master.php.net/note/delete/62785/spam Del: non-english -- http://master.php.net/note/delete/62785/non-english Del: in docs -- http://master.php.net/note/delete/62785/in+docs Del: other reasons-- http://master.php.net/note/delete/62785 Reject -- http://master.php.net/note/reject/62785 Search -- http://master.php.net/manage/user-notes.php
