Hello,
I have an Excel spreadsheet that is automatically updated with quotes. I
am doing a project for my BS and I need to grab the information from
this spreadsheet and populate a MySQL database. Any ideas on how to
accomplish that with PHP? The spreadsheet uses a live DDE feed to fetch
information from a third party service and needs to be opened.
This is not a matter of reading a static XLS spreadsheet but what I need
is a DDE way to talk to the open spreadsheet and update the database
when the cells are changed or have a 1 minute loop to go over the cells.
I understand that I can do that with Java with a commercial package
called Java DDE as well but if there is a way with PHP I prefer.
Thanks,
C.F.

There are a few packages on phpclasses.org which may do what you want:
http://www.phpclasses.org
They all seem to use the COM object (http://www.php.net/com) which only
works on windows.
This package might help also:
http://sourceforge.net/projects/phpexcelreader/
and should work anywhere.

Hi all... sorry if this is OT for PHP list... Maybe a reply off-list?
I just wanted to share my .htaccess file in the hopes that I can
hone/fool-proof-a-tize it as much as possible via your feedback and
suggestions.
Here is what I got so far...
I start by turning-on error reporting, then I am converting all non www
traffic to www traffic, and I finish things up by removing "index.php" from
the site url...
[code] -->
# Turn-on PHP error messaging:
php_value display_errors 1
php_value error_reporting 2047
# Power-up the rewrite engine:
RewriteEngine on
# Redirect all non-www traffic:
RewriteCond %{HTTP_HOST} ^mydomain\.com$
RewriteRule ^.*$ http://www.mydomain.com%{REQUEST_URI} [R=permanent,L]
# Remove index.php from url:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+) index.php/$1 [L]
<-- [/code]
What I want to do:
I would like to use mod_rewrite to forward all requests for
http://www.mydomain.com (or http://mydomain.com) to
www.mydomain.com/folder/file.php
Questions:
1. How is my code looking so far? Any potential pitfalls that you can see?
2. Can I combine the conditions and rules into one, more compact, script?
3. Any suggestions on how I would go about adding-in a rule/condition to
redirect users to "....com/folder/file.php" as stated above?
Many TIA,
Sorry if OT.
Cheers,
Micky

Do you need to do it with a mod_rewrite?
if not, you can do it easily in php:
header('location: folder/file.php');
exit();
in index.php.

Unfortunately, yes... I am using a CMS, and my current setup is forcing me
into using the more complicated mod_rewrite.
Well, not that it is a bad thing... seems like mod_rewrite is more
search-engine/bot friendly.
Thanks for the tip though, I really appreciate your time.

Well, I added this to the end of my .htaccess:
# Set the index page:
RedirectMatch ^/$ http://mydomain.com/folder/folder/index.php
Seems to work well, but I am still concerned about
pitfalls/optimization/consolidation... er, perfection? ;)
TIA, Cheers,

I am writing on a script that parses a PHP script and finds all function calls
to check, if these functions exist. To do this, I needed a function that would
strip out all text, which is enclosed in apostrophes or quotation marks. This
is somewhat tricky, as the script needs to be aware of what really is an
enclosed text and what is PHP code. Apostrophes in quotation mark enclosed text
should be ignored and quotation marks in apostrophe enclosed text should be
ignored, as well. Similarly, escaped apostrophes in apostrophe enclosed text
and escaped quotation marks in quotation mark enclosed text should be ignored.
The following function uses preg_match to do this job.
[···]
I noticed that this function is very slow, in particular because
preg_match("/^(.*)some_string(.*)$/", $text, $matches);
always seems to find the *last* occurrence of some_string and not the *first*
(I would need the first). There is certainly a way to write another version
where one looks at every single character when going through $text, but this
would make the code much more complex.
IIRC regexp search from left to right but match from right to left,
hence going trough the string while the first part matches and going
backwards every time the next part fails to match, and so on for the
whole expression, that's why "(?>...)", "once-only subpatterns", exists for.
Now, you're telling (from left to right) to look for "any sequence of
any characters followed by 'some_string' and, once again, followed by
any sequence of any characters". As long as "(.*)" matches it will loop
the whole string till it fails, once it does it will try to match
"some_text", if it doesn't it will try to match "some_string" once again
from the current position minus one and so on, until it matches (or
"(.*)" fails --at the beginning of the string), after "some_string"
matches it will repeat the first step for the second "(.*)" on the
pattern, so the process will be quite slow.
--I hope this has had some sense for you (somehow it lost it for me)
Also, by default regexp are "greedy", which means "+" and "*"
meta-characters will go on and on. In your case, you most likely will
need to "limit" this behaviour by specifying them as "ungreedy" (that
is, it will try to match the next part after each "+"/"*" matches), you
can do this adding a "?" after these meta-characters (e.g. ".+?-")
I wonder, if there is a faster *and* simple way to do the same thing.
Mhh... what about something like
preg_replace('/(["\']).*?(?<!\\\)\\1/X', '', $code)
? it's not 100% accurate, though, if you find something like '\\' it
will fail --I guess you should replace these before running the regexp
After trying a little, I found that this code below seems to be quite
acceptable, you may want to try it:
/**
* Returns an array with the identified function-calls found
* (including "function declarations", e.g. "function my_func")
*
* @param string $code
* @return string
* @since Mon Apr 10 01:13:28 CDT 2006
* @author rsalazar
*/
function getFunctionCalls( $code ) {
$result = FALSE;
// try to strip away literal strings
$code = preg_replace('/(["\']).*?(?<!\\\)\\1/X', '', $code);
// look for "function calls"
if ( preg_match_all('/(?>((?:(?<=\b)function\s+)?\w+)\s*)\(/Xi',
$code, $arr_matches) ) {
$result = $arr_matches[1];
}
return $result;
} // getFunctionCalls()

So use the built in tokenizer functions which know exactly what's
enclosed text and what is php code. Much quicker and more reliable
than trying to do the same job with regular expressions.

Does the imap_search support multiple criteria?
I've got the following successfully returning the correct results:
<?php
$search[0] = "BODY \"test\"";
$search[1] = "SUBJECT \"test\"";
foreach ($search as $criteria) {
$search_result[]=$imap_search($mailbox,$criteria,$SE_UID);
}
?>
However, when you try and put them in the same search
e.g. $search = "BODY \"test\" OR SUBJECT \"test\""
It fails...
The only way in which I can see this can be done is by joining the various
arrays that are returned. Is this best?
Thanks

Hi to all,
I have the following pattern for a string:
text1 /ptext2 /otext3
Now, I want to extract the text by "patterns" from this string by the following
rule:
no pattern -> text1 (what is before /o or /p)
/p -> text2 (what is after /p)
/o -> text3 (what is after /o)
The order betweeen /o and /p can be switched, so there is no rule that /p is
before /o.
How can I do this? I tried ereg but no success.

The ideea is to extract the texts before and between /o and /p.
$html = "asdäüü ö ö vf /pxtestxx/ostestss";
eregi("^([^/.*]*)", $html, $reg); print_r($reg); //text is in reg[1]
eregi("^(.*)/p([^/.*]*)", $html, $reg); print_r($reg); //text is in reg[2]
eregi("^(.*)/o([^/.*]*)", $html, $reg); print_r($reg); //text is in reg[2]
This example works, but I thought there might be a better way to extract the
texts, with a single ereg or preg_match.

Andy.

Ave,
I had to eliminate that option because his IP is varying drastically. There
is no range, it's just drastically varying. I wouldn't be surprised if he's

I am working on creating some RSS feeds on my website using PHP. I'm still
learning RSS but it seems easy enough. I managed to create the RSS giving
the file a PHP extension. When I tried saving it with an xml extension and
adding a .htaccess file to the directory in which the file was saved, I get
prompted to save the file instead of being able to view the file in a
browser. The only line in the .htaccess file is AddType
application/x-httpd-php xml.
First off, and I'm sorry that this isn't a PHP specific question, but does
RSS require an XML extension? And if it does, how do I get the server to
serve the PHP file correctly if I rename it with the xml extension?
Thanks,
Robbert van Andel

No, you can use any extension you like for the RSS document, including
.php its the contents that matters.

I had similar problems when trying to roll-my-own RSS feed with php.
Michael is right that it doesn't matter what your file extension is
(you probably don't even need that htaccess directive) as long as the
file is served as XML. Try adding a header at the top of the file:
header("Content-type: text/xml; charset=utf-8");
<rss version="2.0">
<channel>
...
I also use the Firefox browser which has a built-in XML browser that
allows me to do a quick validation of the XML. You can also use
www.feedvalidator.org to troubleshoot your feed once its online.

*lol*. personally I prefer the other format which was what I tried to
illustrate with my original example:
<?php
$a = 'f_a';
$a( $p1, $p2, $p3 );
?>
All it means, is that once you have the name of a function in a variable
you can invoke the variable as a function and it will invoke the
function matching the variable's value. Some of this stuff can be really
useful for doing backwards compatibility with older versions of PHP:
<?php
function my_slowass_ctype_alpha( $chars )
{
return eregi( '^[[:alpha:]]+$, $chars );
}
if( function_exists( 'ctype_alpha' ) )
{
$ctype_alpha = 'ctype_alpha';
}
else
{
$ctype_alpha = 'my_slowass_ctype_alpha';
}
if( $ctype_alpha( 'weeeeee' ) )
{
echo 'Alpha chars only!';
}
else
{
echo 'Not alpha chars only!';
}
?>
Cheers,
Rob.
