range() warns if a step exceeds the distance between the min and max values if you are putting that
kind of web development. Should just make that coding more properly - https://ava.codes/hire/angular-developer

There is no convention or necessity to document every warning or error that a function may produce.
I don't see a reason for this bug to remain open.

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
)
