Bug description: escapeshellarg() does not quote percent (%) correctly for
cmd.exe
Description:
------------
On win32, the function escapeshellarg() replaces percent characters (%)
with spaces. Instead, the function should escape the percent character,
perhaps using the ^% construct, so that the percent sign can be safely used
as a an argument to an application executed through exec().
Reproduce code:
---------------
<?
// .... This creates a directory called "Test dir" (without the
quotes)
// .... which is unexpected.
$cmd = 'md';
$arg = 'test%dir';
$fullcmd = $cmd.' '.escapeshellarg($arg);
// .... This creates a directory called "Test%dir" (without the
quotes)
// .... which is the expected result of the above.
// $fullcmd = 'md test^%dir';
exec($fullcmd);
system("dir /B");
?>
Expected result:
----------------
test%dir
Actual result:
--------------
test dir
