Bug #18299 Updated: arsort works different on PHP 4.1.2 and PHP 4.2.0

ID: 18299 Updated by: hholzgra@php.net Reported By: glimpse@glimpse.fr.fm -Status: Open +Status: Bogus Bug Type: Feature/Change Request Operating System: Linux RedHat 6.2 PHP Version: 4.2.0 New Comment: because we use a more efficient sort algorithm now the result is different here, but still correct, your array elements are perefectly sorted before and after the asort() calls whenever two elements are equal the sort algorithm has the freedom to chose which to put first ... Previous Comments: ------------------------------------------------------------------------ [2002-07-12 05:19:10] glimpse@glimpse.fr.fm It seems like the arsort() function sort associative array strangely. The same script does not give the same result: $fruits = array("d"=>"test","a"=>"test","b"=>"test","c"=>"test"); arsort ($fruits); for (reset ($fruits); $key = key ($fruits); next ($fruits)) { echo "fruits[$key] = ".$fruits[$key]."\n"; } Result with PHP 4.1.2 : fruits[d] = test fruits[a] = test fruits[b] = test fruits[c] = test (with this order : d, a, b, c) Result with PHP 4.2.0 : fruits[c] = test fruits[b] = test fruits[a] = test fruits[d] = test (with this order : c, b, a, d) Why does the arsort() function change the order of the elements when they have the same value in PHP 4.2.0 while not in PHP 4.1.2? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18299&edit=1
