This sounds like a problem with apache it self(?).

This sounds like a problem with apache it self(?).
I thought this first too. The problem was solved by getting a new snap
(and the great help of Cyruss).
*AND*:
I always put the php4ts.dll near the sapi/php4apache.dll as stated as a
possibility in the install.txt. But this doesn't seem to work anymore in
PHP5. I moved it to the Apache-Dir and everything works fine.

So it was an apache related problem(?).

The following script is from Kevin Yank's book (Sitepoint).
When I test it _without_ entering a name in the text box and hit submit, the
_next_ page
loads - however the same page should load beacuse of the conditional
........
if (!isset($name) ):
.....
If I replace
!isset()
with
empty()
like
if (empty($name)):
and do not enter a name then the _same_ page loads which is what is supposed
to happen.
Why doesn't the call to !isset() with the negation mark loads the next page
when a name is not entered?
The script predates globals being turned off and it is below.
Thank you.

What do you get if you do:
if (isset($a)) {
print '$a is set';
} else {
print '$a is not set';
}
$a = "";
if (isset($a)) {
print '$a is set';
} else {
print '$a is not set';
}
You get:
F:\>c:\PHP\php -f test.php
$a is not set
$a is set
F:\>
Why? Becasue pointing to an empty string
is not the same as having no pointer at all.
Does this solve your problem?

By the way, it might be interresting to see what this does:
if (strlen($a)) {
print '$a is set';
} else {
print '$a is not set' . "\n";
}
$a= "";
if (strlen($a)) {
print '$a is set';
} else {
print '$a is not set' . "\n";
}

If you get a chance please run the following script _without_ entering a
name in the textbox.
Does the same page load after you hit submit or does a different page load?
Thank you.

Anthony Ritter,Hello！
Here is my test result:
<html>
<head>
<title> Sample Page </title>
</head>
<body>
<p>Your name: </p>
<p>This paragraph contains a <a
href="newpage.php?name=">link</a> that passes the name
variable on to the next document.</p>
</body>
</html>
It's all right under Apache/2.0.44 (Win32) & PHP/4.3.1.what problem you met
is that you turn off the globals_register.If that,you will never get the name
varibles by $name,but $_POST['name'] or $_GET['name'] or $_REQUEST['name'].
Mend your code like this:
<?php if (!isset($_REQUEST['name']) ): ?>
May this helps you,
Yong Woody
