PHP version: 4.0.4pl1
PHP Bug Type: Scripting Engine problem
Bug description: string compare with "==" does not work correctly
First the test script:
<?
$a = '012345678901234567';
$b = '012345678901234568';
echo ($a == $b) ? "a equal b\n" : "a not equal b\n";
echo ($a === $b) ? "a equal b\n" : "a not equal b\n";
printf ("as string: a=%s b=%s\n", $a, $b);
printf ("as float: a=%.0f b=%.0f\n", $a, $b);
printf ("as int: a=%d b=%d\n", $a, $b);
?>
and its output:
a equal b
a not equal b
as string: a=012345678901234567 b=012345678901234568
as float: a=12345678901234567 b=12345678901234567
as int: a=2147483647 b=2147483647
Zend trys to convert the arguments to numbers if both
arguments are strings. This is not good and its not a
feature.
