Bug description: 'if' bug
Description:
------------
hi there!
I'll past some code here to explain my problem.
I dont know if it is a bug or not bug it looks like one to me!
I had some real ugly problems because of this.
If you have a look at the output of this code you'll see what i mean!
if php commpares 0 with any string the if function tells us that this is
true.
I cant believe that the language should be like that so I wrote this
bug-report.
Reproduce code:
---------------
$test_char = 'a';
$my_array = array(0, 1, '0', '1', 'a', 'b');
for($i = 0; $i < 6; $i++)
{
if($my_array[$i] == $test_char)
echo("php's 'if' tells us that {$my_array[$i]} is the same
as {$test_char}\n");
else
echo("php's 'if' tells us that {$my_array[$i]} is not the
same as {$test_char}\n");
}
Expected result:
----------------
php's 'if' tells us that 0 is not the same as a
php's 'if' tells us that 1 is not the same as a
php's 'if' tells us that 0 is not the same as a
php's 'if' tells us that 1 is not the same as a
php's 'if' tells us that a is the same as a
php's 'if' tells us that b is not the same as a
Actual result:
--------------
php's 'if' tells us that 0 is the same as a
php's 'if' tells us that 1 is not the same as a
php's 'if' tells us that 0 is not the same as a
php's 'if' tells us that 1 is not the same as a
php's 'if' tells us that a is the same as a
php's 'if' tells us that b is not the same as a
