I really hesitated putting this in as a bug, because it seems so simple.  The urlencode() documentation seems to imply that the following script should work fine, however it fails to output the second printf() on my system.  I am running with the php.ini-recommended INI file on Windows NT 4.0 SP6.  (I've tried various combinations of htmlentities() and htmlspecialchars() with the urlencode() as well, but so far without success.)

Here's the script:

<html>
<head>
</head>
<body>
<?php
$test_str = "Mickey's Fun House";
printf ($test_str);
$encoded_str = urlencode ($test_str);
printf ($encoded_str);
?>
</body>
</html>

If this is something stupid on my end, I apologize for the bother.

Thanks,
Dave Barndt

Sorry, but the bug system is not the appropriate forum for asking
support questions. Your problem does not imply a bug in PHP itself.
For a list of more appropriate places to ask for help using PHP,
please visit http://www.php.net/support.php

Thank you for your interest in PHP.

do not use printf unless you know what you are doing,
use plain print or echo instead

*and* please have a look at your error log first
before reporting problems

you would have seen a message like

  Warning:  printf(): too few arguments in ... on line 9

due to the fact that urlencode() converts your string to
"Mickey%27s+Fun+House", so requesting to output the 2nd parameter (not given here) as a 27 character wide string

see http://php.net/print and http://php.net/print for 
the different semantics of print() and printf()

Thanks for the reply.  As a C/C++ developer for 13 years, but having only recently been introduced to PHP, I am painfully well aware of the joys and pitfalls of printf() functionality, and will look into print() as you suggested.

Probably because of the late hour, I neglected to check the log or support site.  So much for my first PHP bug submission.  I thought it was probably something stupid.  My apologies for wasting your valuable time.
