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
