<para>
This function does not generate cryptographically secure tokens,
in fact without being passed any additional parameters the return
value is little different from <function>microtime</function>. If
you need to generate cryptographically secure tokens use
<function>openssl_random_psuedo_bytes</function>.

Under Cygwin, the <parameter>more_entropy</parameter> must be set
to &true; for this function to work.
