Thank you for your bug report.

The behavior you describe is by design. If there are n delimeters, explode() returns n+1 elements. It splits the string using a space, and thus also splits using the first space. Because there is nothing before the first space, the first element of the array is empty.

In this case, you can first trim() the string to remove spaces.
