I have an Oracle 8 problem. Unfortunately, I can't use the OCI functions and must use
the ORA functions. The code below looks fine to me. It will return *almost* all of the
rows, but then the script just dies with no warnings or errors, even though I have
called error_reporting(E_ALL). I do get the following error message in an Apache error
log:
Ora_Parse failed (ORA-00936: missing expression -- while processing OCI function
OPARSE).
Here's my code:
<?
$query = "select $columns from $table where $where_clauses";
ora_parse($cursor, $query) or die("<br>ora_parse() failed: ".ora_error());
ora_exec($cursor) or die("<br>ora_exec() failed: ".ora_error());
print '<br><br><a name=results><table border=1>';
$rowcount = 0;
while(ora_fetch($cursor)) {
print '<tr>';
for($i=0; $i<sizeof($columns); $i++) {
$cell_data = ora_getcolumn($cursor, $i);
if($cell_data === false)
die("ora_getcolumn() failed: ".ora_error());
print "<td>$cell_data</td>";
}
print "</tr>\n";
}
print '</table>';
?>
Thanks for any advice.

I modified that code to make it more readable. You may be wondering why the $columns
variable looks like a string and then later like an array. Don't worry....there's no
bug there. The $query variable actually equals "select ${columns_imploded} from
${state}_spell where ${where_clauses}";

PHP is a server side scripting language, which means it is parsed by software on the
server before anything is sent to the client. That's why you don't see any PHP code if
you look at the source of a web page on a client machine.
The opening and closing of windows, on the other hand, is something that happens on
the client side and depend on the client's browser, among other things. PHP has
*nothing* to do with the client's browser other than the fact that it receives some
identification information from the browser. In order to pop open windows or do
anything
else on the client's computer, you'll need a client-side scripting language, i.e. one
that is
processed on the client's computer. One such language is JavaScript, which will take
care of all your window-opening needs.
Hope this helps,
Erik

Don't send output to the browser before you try to send headers().

If you don't want to trawl through those search results then read the error
message again (carefully, all of it). If you still haven't figured it then
read the manual entry for header(), every single line, then correlate what is
said with the error message.

I'm sure regulars on the list are just as frustrated at how often this
question crops up and at how little research people do before asking another
FAQ.

Jason,
I appreciate people get just as frustrate by reading repetative posts.
Alliare and Macromedias forums for ColdFusion and other software, allow a
search through the entire post, archive everything. Which always avoid this
problem of a newsgroup. Maybe I'm wrong, but I don't thing there's a search
like this for a newsgroup?
If you do happen to know, as it would appear you may, the url of the answer
to the original question, then could you simply supply it.
I'm new to this code, I appreciate any assistance, and I will troll through
archives etc to get it. However, if some kind sole can save me 3 hours
work, I'll also appreciate it, which is probably why this list get
repetative posts.
Cheers, relax, and have a nice day.

Got to agree with Jason's comments - as I'm sure all other regulars on the list will
do.
I've just had a quick look at the php.net site, done a search for "header" and halfway
down the first page returned found this:
"Remember that header() must be called before any actual output is sent, either by
normal HTML tags, blank lines in a file, or from PHP. It is a very common error to
read code with include(), or require(), functions, or another file access function,
and have spaces or empty lines that are output before header() is called. The same
problem exists when using a single PHP/HTML file."
Not hard is it?

Michael Egan

Assuming you're running Windows, do what I do and download the Windows
CHM help file version of the PHP manual. It includes standard
search capabilities, so clicking on Search and entering "header" will
bring you back exactly what you need to know.
In this case it's the top 2 results.
Takes like 3 minutes at the most.
Then if the manual description doesn't help enough you can check out
the on-line annotated manual and post messages to this list without
receiving sarcastic replies back again.

Yes, ASP does similar with Response.Redirect - but you're in PHP land
now so why not get yourself a copy of the PHP bible? It'll save you SO
much hassle.

Hello all,
What I have:
Windows webserver running PHP 4.34 and MySQL 4.0.17.
The knowns:
Doing the PHP test works and I get back all sorts of information,
and PHPBB2 works as advertised with no problems, so does PHPMyAdmin.
My Problem:
I've tried a number of PHP scripts to do various things (some just to
play around and learn, and some because I really want them on my web
server.) The three problems I usually encounter with the problematic
PHP scripts are:
1. When I hit the page, it just returns a blank page. This happens
with:
PHPTest http://www.resynthesize.com/code/phptest_info.php
Proxy http://sourceforge.net/projects/sbp/
2. When I hit the page, it needs some authentication for login, and
even though it appears to take the login, nothing really happens
(i.e. it didn't log me in, so I can't go anywhere. This happens
with:
Scubaman Dive Log http://www.ivains.com/scubaman
Directory Indexer http://autoindex.sourceforge.net (only when I
enable the authentication for user logon,
otherwise it works fine)
3. Parts of the PHP script work, but others don't. This happens with:
GoRedirector http://www.studentplatinum.com/scripts/ (It will
return the values from MySQL that are in there, but I can't delete,
add, or administer it in any way, nor does the actual PHP
redirector itself work.)
I don't know enough about PHP yet to really know where to start
looking. Any help would be greatly appreciated. I thought it had
something to do with Global Variables being disabled in the php.ini
file, but I re-enabled that to test it, but it didn't help.
Cheers,
Leif Gregory

Just a followup. I found out that the PHPTest showing just a blank
page was a mistype in my config.inc.php file. It now shows me the
login screen, but when I login it does not do it. If I create a new
user via the PHPTest interface, it does indeed create the new user,
but I can't login with that one either.
I know I'm asking about a specific app here, but the problem spans a
few apps, and the problem is the same with all of them (namely,
authentication won't work).
Thanks again.

I'm working on a calendaring script right now, and am stuck on a
programmatic way to figure something out.
Basically, the work day is broken down into 15-minute intervals, where the
value of a given interval can be figured as $hour=floor($i/4) and the
minutes can be figured as $minutes=($i%4)*15. So 32 = 8:00, 33=8:15, etc.
Currently, it's relatively easy to pull up a day, and block out those times
that are already taken up with appointments. I'm throwing them all into an
array ($available_times). So, that array would look like:
32=>yes
33=>yes
34=>yes
35=>yes
36=>no
37=>no
38=>yes
39=>yes
etc, for someone who has a meeting from 9:00 to 9:30.
Now, what I'm trying to do is check when they schedule a new meeting so that
they don't overlap their times with something that's already taken up. So,
in the array given above, if they select 8:30 as the start time, I'd like
them to be able to select 8:45 or 9:00 as the end time, but nothing later
than that, as the time from 9:00 to 9:30 is already taken up.
And I'm stuck trying to figure out an approach to this. Preferably one that
I can throw into javascript so they can fix their errors before it ever hits
the server.
Any help appreciated.

I suggest a bit's mask technique; since max(i)=96, you can represent a day
by 96/8 = 12 bytes = 3 (32-bits integers).
TimeFrameA is an integer representing the first 32 15-minutes chunks(0-31),
TimeFrameB represents 32-63, and TimeFrameC 64-95.
If a bit is 1 the you that 15-minutes chunk is marked as "busy", 0
otherwise. It is easy to find which is the first 'busy'bit in each
TimeFrame:
// at least one bit is marked as busy
if (TimeFrame <> 0)
{
mask = 0x80000000;
while (mask & TimeFrame == 0)
mask = mask >> 1;
}
Hope this helps (I think it saves both memory and time)

Clearly, I'm going to have to get on the PHP short bus. I was never any
good at bitmasking.
In the meantime, I've got it working. Not elegant, mind you, but working
nonetheless. Thanks.

Hi all,
I programmed a server to bind to an external server(Let's call it
C-server). My server will have to listen on the connection to C-server
and send over data frequently. Each write of data to C-server from my
server will cause C-server to response a string.
So the codes will be something like this:
if($response)
{
socket_write($read_socket, "$response", strlen($response));
echo $response."\n";
}
...
some processing to construct string to be send over
...
foreach($message as $part)
{
socket_write($this->c_socket, $part);
echo $part."\n";
$out = socket_read($this->c_socket, 1024);
echo $out."\n";
error_log($part.":".$out."\n", 3, $this->logfile);
}
Everytime the execution reaches socket_write($this->c_socket, $part);
a php warning is issued
<br />
<b>Warning</b>: socket_read() unable to read from socket [11]: Resource
temporarily unavailable in
<b>/var/www/html/dreamscape_mg/connectors/celcom/mo.php</b> on line
<b>134</b><br />
Line 134 is the curl brace after the foreach. I am assuming that the
socket read would be $out = socket_read($this->c_socket, $part). Why do
I get the warning? c_socket is non blocking.
Thanks for your help

I am not sure about sending messages, but here you may find a couple of
classes that can communicate with MSN messenger servers.

The example in the manual shows how to open a zip archive and read each file
into memory and display. It should be a straight forward matter to use the
functions in "Filesystem functions" to write the uncompressed files to disk.

HI all,
I am querying a db and getting the resultset, then to get out each
individual field of the resultset (which is a single unique line all the
time) as mysql_result($result2, 0, "p_company"). the problem is that if the
actual field has a space in it say "Sun microsystems", I only get "sun" and
it doesnt give me anything after the first space.
I have looked at the manual but as far as im concerned its really vague in
its description of alot of the mysql functions.
any idea what could be causing this??
thanx Angelo

i would try the following:
- check if it works with $GLOBLAS['_SERVER']['REQUEST_URI']..., but I think
your implementation should work then, too.
- so: if you don't necessarily need this var to be a real class var (with
the only disadvantage not seeing it when asking for
get_class_vars("Class")) then let the var set by the constructor:
<?php
class Foo {
var $location = "";
function Foo() {
$this->location = $GLOBLAS['_SERVER']['REQUEST_URI'] . ...;
}
}
?>
hope i could help.
