Hi,
I need to extract the first digit after the decimal point from a number such
as 28.56018, which should be '5'.
Since no one came up with the simple solution:
$num = "28.56018";
ereg("^[0-9]+\.([0-9]){1}", trim($num), $regs);
if($regs[1])
$digit = $regs[1];
else
print "no digit found";

I do exactly this, its handy to be able to check out the latest version of
a website, make some changes and commit it again, while having acsess to
the complete revision history, from absolutely anywhere.
SVN works over HTTPS, so can go straight through most firewalls without
anyone noticing and it also does data transmissions (like RSync) which can
be a LOT faster than re uploading the whole file with SFTP etc.
There are some security issues in a shared hosting environment though, if
you use a commit hook to update the web root on commit using a file:///
URL anyone on the server could check out / commit files from the
repository. As of right now the only work around that I can think of for
this would be to run two apches at the same time, one for SVN, and one for
the main HTTP server which is chrooted to block access to the SVN repos
and have the non chrooted server revere proxy connections to the chrooted
one.

true, check that as well, moreover, you talked about utf-8, well, if the
BOM is automatically added, it can cause lots of problems ... still,
only if you sent whatever to the output before the download.
I've tried a bunch of things, including link to index.php and as first
thing check if the request is a zipfile, then throw a zip header,
readfile the file then exit the code. Nothing helped. So I figured it
could be a latin-1 / utf-8 problem and tried to post to a fresh new page
(donwload_zip.php) instead, where I was sure the terminal and Vi was set
to use latin-1, then it worked.
It's still not the ultimate solution as we wanted the zipfile to be
created on the fly in memory in order not to have to delete files
afterwards and to be sure that only allowed users can fetch the files
(of course you can always put the zipfiles outside webscope, but still...)

Hello,
Will be ever see built-in debugging features for PHP?
I kjnow there's xdebug but it's sometimes difficult to get it working. I'm
hopoing that PHP will one day have intgrated debuging features that can be
easily enabled or disabled:
<?php
enable_debug(true);
debug_console("Hello world!'); // sends an output to the console of the
debugger.
?>
Personally, I've found that turning on "error_reporting(E_ALL)",
debug_backtrace() and debug_print_backtrace() quite adequate for most situations.

I do not expect there would be. Debuggers are more likely to be provided
by the IDE. For example, in MS-Windows, Visual Studio is the IDE and can
include any of several compilers. It also includes the debugger, and
uses the same front end for all languages. Of course, Microsoft has it
much easier since they only support one hardware platform (x86) and one
OS. Unlike the rest of the world where tools are more likely to be
portable.
For an IDE with debug capabilities, try NetBeans. I am sure there are
others, but that is the only one I have actually looked at.

Real coders don't use debugging tools, comments and output statements
are all you need ;)

I agree with you and that's why I said in my first message "Personally, I've
found that turning on "error_reporting(E_ALL)", debug_backtrace() and
debug_print_backtrace() quite adequate for most situations."
In fact, I don't recall even using debug_backtrace() and debug_print_backtrace()
in the last couple of years.
I script very robust code and it catches damn near all errors itself.

No, we simply use debug or ddt to insert machine code directly into
memory. But that tends to get tedious very quickly, so experimenting
with other options is one way to relieve the boredom.

I find having a custom error handler that uses debug_backtrace() to
produce a limited stack trace very useful for finding errors sometimes.

I have to disagree, while Exception handling and the like have their
place. Sometimes when you develop you want to stop execution and look at
your memory stack to make sure you didn't over look something.
Especially if you are relying on someone else code and it's not a project
owned 100% by you.
Just my thoughts, they have their place I use PhpEd, because it facilitates
this nicely and it VERY customizable from a short hand perspective.

Hi,
in the Java Xalan XSLT processor there is an URIResolver object to
resolve URIs used in xsl:include, xsl:import, etc.
http://xml.apache.org/xalan-j/apidocs/javax/xml/transform/class-use/URIResolver.html
With this URIResolver you can comfortably implement your own logic to
load external resources.
A small example how it works in Java, so maybe my problem is easier to
understand:
TransformerFactory.newInstance().setURIResolver(
new URIResolver() {
public Source resolve(String href, String base) {
// all included files are relative to c:\temp
return new StreamSource(
new File ("c:\\temp\\"+href));
}
});
and so statements like:
<xsl:include href="include.xsl"/>
will include c:\temp\include.xsl
Now my problem is, that i need this functionality in PHP´s XSLTProcessor.
Generally I think libxslt already supports the same functionality with
the xsltDocLoaderFunc:
http://xmlsoft.org/XSLT/html/libxslt-documents.html#XSLTDOCLOADERFUNC
anyone have an idea how to handle that problem?
thanks a lot

Hi.
I've got a situation where I have a couple of tables. The relationship
between the tables is one of parent/child. I'm trying to figure out the best
approach to being able to delete the associated children in the child tbls,
of a given parentID in the parentTBL...
I've checked into various sites/articles on the 'net.. but i'm not sure how
best to accomplish this...
I'm using php as the interface language to the test tbls..
Any pointers/articles/test code (code/schema) would be helpful...
Thanks

Well if the tables truly have a relationship, then no PHP is necessary.
I assume that to connect the 'parent' row with the 'children' rows of
the secondary table you've used an identifying field. For example:
users table:
user_id
forename
surname
emails table:
email_id
user_id
email_address
So in the above example, a user on the users table could have several
entries in the emails table for each email address they have.
emails.user_id will match up users.user_id so you can run a query like
DELETE FROM emails WHERE user_id=id
Is this any help?
Thanks,
Ash
