Hi all,
I'm afraid that recent changes in filestat.c [1] that were meant to fix
a bug [2] with file_exists() also altered the behaviour of
is_readable(). According to the docs [3] [4], is_readable should *not*
take safe_mode limitations into account, whereas file_exists should do.
<?php
print PHP_VERSION . "\n";
var_dump(ini_get('safe_mode'));
var_dump(file_exists('/etc/hosts'));
var_dump(is_readable('/etc/hosts'));
?>
[EMAIL PROTECTED]:~$ php bug.php
5.1.6
string(0) ""
bool(true)
bool(true)
[EMAIL PROTECTED]:~$ php -d safe_mode=1 bug.php
5.1.6
string(1) "1"
bool(false)
bool(false)
Is this intended behaviour? If not, I'd be glad to file it as a bug.
Kind regards,
mp.
