PHP has a number of builtin "String Functions" which does string similarity
comparisons. I'm not sure how useful they would be for your purpose so you
would have to play around with them to find out.

The guys in the internals list sent me to this forum.
I am trying to write some serious parsing software in PHP. I need to use plain,
vanilla PHP and no add-on modules, because I need to be able to distribute to people
who don't have sufficient privileges.
In the process of parsing I create a new document composed of concatenated pieces of
the original document. I am efficiently catting the new document using output buffer,
but when I have to copy non-contiguous pieces form the original document, I am forced
to create substrings, as in:
echo substr($originalDoc, $startOfSnippet, $snippetLength)
My documents are potentially large with possibly thousands of such substrings. I know
from writing Java parsers for high-throughput servers that object creation, and in
particular string creation, is the greatest source of degraded performance.
I'd like to copy the contents of a substring directly to the output buffer without
creating an intermediate object, as in:
ob_write($string, $start, $length)
I can find no such function and could envision no other way to do this at present.
When can I expect broad support for such a function in the base PHP release? Or do
you know of a workaround?
BTW, because I had to ditch my last email address due to spam, I'm subscribed to this
list through spamex.com. But because the list makes the emails it distributes appear
to original from the people who posted, I have no way to reply through spamex back to
this forum, at least no way to keep the reply in the same thread. Suggestions, are
welcome. Otherwise I'll be starting a new thread.
Thanks for your help!

I'm not entirely clear at what your trying to do but perhaps you
want something like this:
function print_substr_direct($string, $start, $len) {
static $fp = null;
if ($fp === null ) {
// Open a connection directly to the output
$fp = fopen('php://stdout', 'r');
}
if ($fp) {
fputs($fp, substr($string, $start, $len));
}
}

Again, the internals list sent me to this forum for help.
In trying to create a series of parsers in PHP, using only PHP core and no
non-standard add-ons, I find myself emulating multiple character streams in a class
that wraps the output buffer. Every time I open a new stream, I first save the
current contents of the output buffer and then reset the stream. When the stream is
closed, I then restore the output buffer to what it was before.
I'd like more conventional 3GL behavior, where I am permitted multiple buffered
streams via handles or stream objects. I see no way to do this with PHP as it stands.
I also don't see anyway to emulate this without worsening the problem by creating a
profusion of strings.
I'm mostly able to work around the performance inefficiences of this wrapper-class
approach by making the application smart about when to use a new stream. But I'd
rather have native support.
When can I expect to see this kind of conventional stream behavior in PHP? Are there
any workaround I can use in the meantime?
Thanks for your help!

Why are you looking for such low level functionality in what is
essentially a scripting language? If you're this worried about speed,
you should probably be writing this in C. Or make an extension to PHP.
I know that you say "no non-standard extensions", but if you can't
have an extension, you're not likely to have any major speed
increases.

Portability I would wager. And portability with as much efficiency as
possible. I guess the current streams implementation requires him to
perform a lot of low level emulation to get past perceived deficiencies
in the stream handling architecture. Not every Joe has the luxury of
installing extensions and so often a PHP script can provide the widest
possible audience.
Cheers,
Rob.

With the example listed, you can have as many buffers as you
please.

Yeah, actually, you were right. I must have misunderstood the instructions
- probably because of the press for time, reading too quickly. I wasn't
using "--with-jpeg-dir", etc. Sorry for the mess, and thanks for all the
help. At least some good came out of this -- I now have a working Slackware
installation (after the headaches, I decided to install Slackware 10 on my
unused server and compile everything from source to see if I could get it to
work). Thanks for your time everybody.

Hmm.. I just did some more playing, and I solved the problem for me! It
seems that the program did not have write permission to the temp folder
because I was running in safe mode (I found this out by enabling all error
messages with 'error_reporting (E_ALL);'. After I redirected the temp folder
to a place that apache could write to, everything started working. Here's
the final working code:
$workbook = new Spreadsheet_Excel_Writer();
$workbook->setTempDir('/apache_tmp/');
$workbook->send('test.xls');
$worksheet =& $workbook->addWorksheet('Testsheet');
$worksheet->write(0, 0, 'Blah');
$workbook->close();
The Problem was solved by Ben Claar and I would like to thank him for his
help in this matter.

Morning guys.
I'm trying to destroy a session using "session_destroy();" and I get the
following error:
"Trying to destroy initialised session"
I simply want a user to click a logout button that destroys the session
cookie. Am I doing this the right way...?

for some reason it was holding the session because I had two browser windows

[/snip]
Strange how? Since the session is active in at least one stateless
browser window you would have to find a way to affect the state of that
browser window with the browser window you wish to log out from. Since
this is a client side issue you might be able to use JavaScript to
affect the state of the other browser window.

Well, I thought it was the good way to do.
It helps me to know which box has been checked (?).
Yes, because

I let the value as it was because I would need to
rename a few hundreds checkboxes :-/ but I had used
your test in PHP if (isset($grid... and it works fine.
In fact it was very simple. When I think the time I
tried to find a solution. Shame on me.
Ok, my excuse is that I'm just learning.
Thank you very much.

You need to do:

Keeping the name the same makes them a RADIO button and you will only

This is a valid solution, but it's really just easier to make them into an
array like many others have suggested. Using this method, you would need to
loop through all of the possible "checkBoxGroupX" values to see which ones
were checked or get a list or count of them. Making them into an array makes
it as simple as count($_POST['checkBoxGroup']) or
implode(',',$_POST['checkBoxGroup']), etc...

This is not true. The only thing that will make these a radio button is
setting the 'type' to 'radio'.
The answers put out to this yesterday were correct. Using square
brackets ( [] ) after the name of the checkbox element will send them as
an array (if any are checked).
