From: Operating system: Linux PHP version: trunk-SVN-2010-08-06 (snap) Package: *General Issues Bug Type: Bug Bug description:range() warns if step exceeds the distance between the min and max values
Description: ------------ The range() function incorrectly warns when the step size exceeds the distance between the min and the max values. But when the min and max values are equal, there is no warning. This is related to #21060 and #46631. The documentation at <http://www.php.net/manual/en/function.range.php> gives no mention of possible warnings or errors. The 'seq' utility is a good guide as to the expected output of the test script. $ seq 1 2 4 1 3 $ seq 1 2 3 1 3 $ seq 1 2 2 1 $ seq 1 2 1 1 Test script: --------------- print "range(1, 4, 2)\n"; print_r(range(1, 4, 2)); print "\n"; print "range(1, 3, 2)\n"; print_r(range(1, 3, 2)); print "\n"; print "range(1, 2, 2)\n"; print_r(range(1, 2, 2)); print "\n"; print "range(1, 1, 2)\n"; print_r(range(1, 1, 2)); print "\n"; Expected result: ---------------- range(1, 4, 2) Array ( [0] => 1 [1] => 3 ) range(1, 3, 2) Array ( [0] => 1 [1] => 3 ) range(1, 2, 2) Array ( [0] => 1 ) range(1, 1, 2) Array ( [0] => 1 ) Actual result: -------------- range(1, 4, 2) Array ( [0] => 1 [1] => 3 ) range(1, 3, 2) Array ( [0] => 1 [1] => 3 ) range(1, 2, 2) Warning: range(): step exceeds the specified range in /home/stevew/Desktop/PHP/php-trunk-201008060430/sapi/cli/test-range.php on line 16 range(1, 1, 2) Array ( [0] => 1 ) -- Edit bug report at http://bugs.php.net/bug.php?id=52551&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52551&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52551&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52551&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52551&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52551&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52551&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52551&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52551&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52551&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52551&r=support Expected behavior: http://bugs.php.net/fix.php?id=52551&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52551&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52551&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52551&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52551&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52551&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52551&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52551&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52551&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52551&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52551&r=mysqlcfg
