[PHP] Call to undefined function problem
I'm doing the following:
test.php -
-- functions.php -
";
function setNoCacheHeaders( ) {
static $headersNotSet = TRUE;
if ( $headersNotSet ) {
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");// Date in the
past
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); //
always modified
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Pragma: no-cache"); // HTTP/1.0
$headersNotSet = FALSE;
}
}
echo "here 2";
// a few more functions here
}
My output is
here 1
here 2
Fatal error: Call to undefined function: setnocacheheaders() in
$DOCUMENT_ROOT/test.php on line 16
Can someone explain? I found something similar in the archives but no
answer was given. This exact code worked under php3. The only changes in
the files were files ending in php3 were changed to end php. I also had 2
classes that I was using that had initializers in the variable declaration.
I moved the initialization to constructors.
Note that on some clients the request goes through w/o errors. This is
intermittent but consistent on a per client basis.

[PHP] Re: Call to undefined function problem
Further information:
The page is navigated to via a previous page using a "Location: /test.php"
header. The problem occurs when I first navigate to the page. If I then
do a refresh from the browser, the problem disappears.
I also did further testing where I put the following type of code between
the requires (a unique number for each statement):
if (function_exists("setNoCacheHeaders"))
{
echo "exists 1";
}
else
{
echo "does not exist 1";
}
In the broken scenario, the function never exists. In the working scenario
it is
always there.
I also neglected to say that I was switching from php3.0.14 to php4.0.6.

Re: [PHP] Call to undefined function problem
Thanks. I ran some further tests and came to the same conclusion. My test
showed that the constant was defined even though in theory it should be a
new request.
Since this is a production system, I don't want to go with a release
candidate. I'm going to do a switchover to "include_once".

Re: [PHP] Call to undefined function problem
Typo in my explanation. I had "defined" in my code. Nice catch though.
However, I'm running into more define issues. When I get to a file through
a redirect via header("Location: /newfile.php"), my defines are existing as
tested by "defined" but the values are all corrupt. However, if I then
refresh the page, the value is good. Anyone else seen this in php-4.0.6?
Can someone explain to me what is fixed for defines in the 4.0.7 candidate?

[PHP] corrupted definitions
I have definitions (i.e. define ("a", "b");) that are being corrupted in
php-4.0.6 in apache 1.3.20 on Redhat linux from Jan. 11.
Anyone seen this? Any solutions?

[PHP] Re: corrupted definitions
Further info:
I'm on Redhat Linux 6.2. The uname output is "Linux web2 2.2.13-0.13smp #1
SMP Tue Jan 11 13:26:01 EST 2000 i686 unknown."
Also, the problem goes away if I set display_errors in php.ini to Off. Can
someone explain? I'm guessing a memory overrun somewhere.
Note that on another machine running Redhat Linux 6.1 with a uname output of
"Linux web3 2.2.16-3smp #1 SMP Mon Jun 19 19:00:35 EDT 2000 i686 unknown",
the problem does NOT occur even if display_errors in php.ini is set to On.

[PHP] scoping: can someone explain to me if this should/should not work?
The following code seems to work in general but everyone once in a while I'm
getting a segmentation fault. Can someone explain to me why this would be
intermittent and/or whether or not it should work?
function getDomain($serverName)
{
$result = $serverName;
// some processing to result occurs here
echo "here 3: $result";
return $result;
}
function test()
{
global $SERVER_NAME;
echo "here 1";
$domain = getDomain($SERVER_NAME);
echo "here 2";
}
When I get a segv, I get the output:
here 1
here 3:
The "here 2" is not displayed. I thought that this would a return by copy
and not have an issue.
