Set up PHP error logging and then in your extension code, put:
error_log("Value of test is :" . $Test_int . ":\n");
That will output to the error log the value bracketed by the text,
something like:
Value of test is :42:
I prefer to bracket the output with some character like a colon ( : ) or
something similar so I can see any preceding or following blanks (or
non-displayable characters) if the variable is a string.
