Description:
------------
I encountered this bug while reading out a CSV file.
The problem here is the fact that PHP cannot parse True/False as a string in this situation.
In the CSV file, rows are built like this:
"True";"26631";"2";"6";"20040521";"2004";"null"

When I loop through the rows, and echo the first value ($data[0]) it says "True" or "False", but when I try to use it in an if-statement, it will always go to the else section.

Reproduce code:
---------------
function convertBoolean($tring)
{

	if($tring == 0)
	{
		$return = "1";
	}
	else 
	{
		$return = "0";
	}
		
	return $return;
}
