Bug #52031 [NEW]: Passing "0" as a parameter through a custom method

From: Operating system: CentOS 5.5 PHP version: 5.3.2 Package: Unknown/Other Function Bug Type: Bug 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!
