... actually i forgot that the default fopen mode is "rb" ... anyhow, here
is what's supposed to happen:
$ touch bug.txt; chmod 0777 bug.txt; php -r '$o=new
SplFileObject("bug.txt");var_dump($o->fwrite("test"));var_dump(error_get_last());'
PHP Notice: SplFileObject::fwrite(): Write of 4 bytes failed with errno=9
Bad file descriptor in Command line code on line 1
bool(false)
array(4) {
["type"]=>
int(8)
["message"]=>
string(81) "SplFileObject::fwrite(): Write of 4 bytes failed with errno=9
Bad file descriptor"
["file"]=>
string(17) "Command line code"
["line"]=>
int(1)
}
changing the code to SplFileObject("bug.txt", "rb");
makes the code work, but there's still the issue with cygwin's php's
SplFileObject::fwrite() not noticing the write error
