This module contains an interface to those functions defined in
|
|
the IEEE 1003.1 (POSIX.1) standards document which are not
|
|
accessible through other means. POSIX.1 for example defined the
|
|
open(), read(), write() and close() functions, too, which
|
|
traditionally have been part of PHP 3 for a long time. Some more
|
|
system specific functions have not been available before, though,
|
|
and this module tries to remedy this by providing easy access to
|
|
these functions.

|
|
<warning>
|
|
<para>
|
|
Sensitive data can be retrieved with the POSIX functions, e.g.
|
|
<function>posix_getpwnam</function> and friends. None of the
|
|
POSIX function perform any kind of access
|
|
checking when <link linkend="ini.safe-mode">safe mode</link> is enabled.
|
|
It's therefore <emphasis role="strong">strongly</emphasis> advised to
|
|
disable the POSIX extension at all (use
|
|
<literal>--disable-posix</literal> in your configure line) if you're
|
|
operating in such an environment.
