+    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.
