It doesn't matter what type of character it is (alpha, numeric, or other). A workaround is to add a space character before or after the value, e.g.: putenv("bar= x"); putenv("bar=x "); (...as long as this space does not cause problems for the consumers of the variable as it will be part of the string value.) Reproduce code: --------------- <?php putenv("foo=ab"); putenv("bar=c"); var_dump(getenv("foo")); var_dump(getenv("bar")); var_dump(getenv("thisvardoesnotexist")); ?> Expected result: ---------------- We would expect the output to be: string(2) "ab" string(1) "c" bool(false) which it does under PHP 5.3.0. Actual result: -------------- string(2) "ab" string(0) "" bool(false) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50690&edit=1
