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

From: glimpse@glimpse.fr.fm Operating system: Linux RedHat 6.2 PHP version: 4.2.0 PHP Bug Type: Feature/Change Request Bug description: arsort works different on PHP 4.1.2 and PHP 4.2.0 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 bug report at http://bugs.php.net/?id=18299&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=18299&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=18299&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=18299&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=18299&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=18299&r=support Expected behavior: http://bugs.php.net/fix.php?id=18299&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=18299&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=18299&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=18299&r=globals
