Bug description: putenv("VAR=") does not empty VAR on win32
It appears that in Win32 (with php-cli.exe), the putenv function works
quite strangely.
When you call putenv("VAR="), this sould empty the "VAR" environment
variable. And it almost does it, because a call to getenv("VAR") will
return an empty string. However, the real env is not changed and VAR is
still set to its old value.
This small script (and its output) demonstrate the problem :
C:\php>php-cli
<?
putenv("TEST=ZOB1");
echo getenv("TEST")."\n"; // "ZOB1"
system("echo %TEST%"); // "ZOB1"
putenv("TEST=");
echo getenv("TEST")."\n"; // ""
system("echo %TEST%"); // "ZOB1" <- should be empty !
putenv("TEST=ZOB2");
echo getenv("TEST")."\n"; // "ZOB2"
system("echo %TEST%"); // "ZOB2"
?>
ZOB1
ZOB1
ZOB1
ZOB2
ZOB2
