Bug #22234 copy() fails if source file has 0 length
Submitted: 2003-02-15 13:28 UTC Modified: 2003-02-15 14:02 UTC
From: greg at chiaraquartet dot ent Assigned:
Status: Closed Package: Filesystem function related
PHP Version: 4.3.0 OS: win98
Private report: No CVE-ID:

if copy('file','dest') is called, and the 'file' is a 0-length file, it will fail.  This causes pear install PhpDocumentor to fail on windows.

To test, create an empty file "emptyfile.php" and a non-empty file "nonemptyfile.php" in the same directory as this script, and run it:

var_dump(copy('emptyfile.php','newfile.php')); // bool(false)
var_dump(copy('nonemptyfile.php','newfile.php')); //bool(true)
