Bug description:Passing "0" as a parameter through a custom method
Description:
------------
Sorry but I didn't know how to best word the summary.
I have a custom method with an if statement inside. If the parameter passed
through matches "Test", a string is echo'ed. However if I pass "0" through
as the parameter, PHP thinks this is "Test" and echoes the string.
Passing a blank parameter through, i.e. "", does not have the same effect
as "0".
Inserting "if (empty($str))" before the if statement in the example works
as expected, catches the "0" parameter and I get the expected result.
However without this, I get the actual result.
All plugins have been disabled and Apache restarted.
Test script:
---------------
<?php
function testMethod($str = 0)
{
if ($str == 'Test')
{
echo 'Test String!<br>';
}
}
testMethod('Test');
testMethod(0);
testMethod();
testMethod(1);
testMethod('Something');
?>
Expected result:
----------------
Test String!
Actual result:
--------------
Test String!
Test String!
Test String!
