Re: [PHP] kadm5 Library
Did you try to install krb5-devel. Try yum search krb5 to see all the available packages that CentOS includes. In case your yum doesn't find something you may add more repos like Dag's: I did. The krb5-devel package is the one that installed krb5/krb5.h, but as I mentioned that seems to be a different version than the one that the PECL library expects. I've used Dag's repository before, but as you pointed out, it doesn't contain this package. What you need is to find a kerberos rpm to include development header in order to compile it your self. I thought about grabbing the header from another OS, but I'm concerned about incompatibilities. For now, I'm just using the expect library and running kadmin.local via sudo as needed. It's clunky, but it's working. :) Thanks for all your help!

Re: [PHP] kadm5 Library
Sorry, I could have been a little clearer: I can't recompile PHP. It's against our general policy to use custom compiled software on the grounds that there are too many sysadmins managing a lot of these machines and if some software is custom compiled and others not, it gets too confusing when it comes to keeping the machines updated and patched. We're talking a dozen sysadmins and hundreds of machines here. :) I did try to compile the PECL library by specifying the path to the Kerberos libraries as you suggested, but it turns out that the normal version of Kerberos seems to have, among other things, a krb5/admin.h header file, and the one that comes with CentOS has krb5/krb5.h instead, and even when I change the source code to use krb5/krb5.h, it still throws about 50 errors talking about missing functions and re-defined functions and so on. I'm thinking that the problem is that the PECL module was designed to work with one version of the Kerberos library and CentOS provides a different version. I guess I was really asking if anyone had any diffs or anything I could apply to the PECL module to make it compile on a CentOS machine. Or perhaps is there a Yum repository somewhere that I could use to get a version of the PECL module precompiled for CentOS? I should point out that the Perl Kerberos module did install and compile successfully on this machine, so I'm fairly sure that Kerberos is itself working.

[PHP] kadm5 Library
Hi, I'm running PHP on a CentOS 5.2 box and I'd like to get the kadm5 library to work. The documentation says that the package is both included by default and also available as a PECL module. The functions are not available in my base install (I'm using the PHP package from the CentOS repository). When I do a phpinfo() I do see that --with-kerberos was specified at compile time, but --with-kadm5 was not, so I'm not sure if that was a typo on the part of the person who did the compilation or if there is something else that --with-kerberos does. Anyhow, I can't seem to get the PECL version to compile. I have the krb5-devel Yum package installed, but it always breaks with an error message that says: checking for kadm5 files in default path... not found configure: error: Please reinstall the kadm5 distribution ERROR: `/tmp/tmp7fT8eC/kadm5-0.2.3/configure' failed It appears to be looking for krb5/admin.h which doesn't exist on CentOS even with the krb5-devel. Instead, CentOS seems to have a krb5/krb5.h which does contain some valid Kerberos headers, but when I modify the PECL library to use that file instead of admin.h, I do get a bit further but then get two or three screens full of error: 'KRB5_KDB_DISALLOW_TGT_BASED' undeclared type errors. So, I guess my question is has anyone had any luck getting this library to compile and function on CentOS 5.2? Can anyone point me in the right direction as far as getting this library to work?

RE: [PHP] Using DOM textContent Property
Nathan, Thanks for your help on this. I actually need to do this a different way I think though. The problem is that I'm not just replacing a text entity with a link entity. For example, consider this paragraph: pFor information, please contact [EMAIL PROTECTED]/p In this case, I want [EMAIL PROTECTED] to be a link, but not the rest of the paragraph. That means that the p entity has to be split into three separate entities - one DOMText for For information, please contact , one DOMEntity node for [EMAIL PROTECTED], and one DOMText node for .. This seems doable with the DOM modle, but complicated. I'm thinking regular expressions might be the way to go again. :\ Tim Gustafson SOE Webmaster UC Santa Cruz [EMAIL PROTECTED] 831-459-5354 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Using DOM textContent Property
Nathan,
Thanks for the suggestion, but it's still not working for me. Here's my
code:
===
$HTML = new DOMDocument();
@$HTML-loadHTML($text);
$Elements = $HTML-getElementsByTagName(*);
for ($X = 0; $X $Elements-length; $X++) {
$Element = $Elements-item($X);
if ($Element-tagName == a) {
# SNIP - Do something with A tags here
} else if ($Element instanceof DOMText) {
echo $Element-nodeValue; exit;
}
}
===
This loop never executes the instanceof part of the code. If I add:
} else if ($Element instanceof DOMNode) {
echo foo!; exit;
}
Then it echos foo! as expected. It just seems that none of the nodes in
the tree are DOMText nodes. In fact, get_class($Element) returns
DOMElement for every node in the tree.

[PHP] Using DOM textContent Property
Hello,
I am writing a filter in PHP that takes some HTML as input and goes through
the HTML and adjusts certain tag attributes as needed. So, for example, if
a tag is missing the title attribute, this filter adds a title attribute
to the a tag.
I'm doing this all using PHP 5 and the DOM parsing library, and it's working
really well.
The one snafu I'm running in to is dealing with users who will just type an
e-mail address into an HTML document without actually making it a link - so,
they'll just put [EMAIL PROTECTED] rather than a
href=mailto:[EMAIL PROTECTED][EMAIL PROTECTED]/a. I'd like for these
incorrectly
entered e-mail addresses to magically change into real clickable links, so
I'd like my filter to be able to grab those plain text e-mail addresses and
convert them to actual clickable links.
I tried iterating through all the elements on a page using something like
this:
$Elements = $HTML-getElementsByTagName(*);
for ($X = 0; $X $Elements-length; $X++) {
... SNIP ...
}
And then I tried looking at the textContent property of each node, but it
seems that higher-level nodes include all the text of their children nodes
(which is what the DOM documents say it should). But there doesn't appear
to be any way to know if the textContent you've got is for just one node, or
for a whole bunch of nodes. Is there any way to figure that out, so that I
can adjust the textContent property of just the lowest-level nodes, rather
than mucking up the higher-level ones?

RE: [PHP] Using DOM textContent Property
if a node has children, then its not a leaf, so i imagine you could continue to traverse until you reach the leaf that actually has the address needing magical conversion. I tried that. $Element-hasChildNodes() returns true for just about everything except tags like br and img that have no corresponding /br or /img because the content that appears between p and /p, for example, apparently counts as a child node, even though they're not HTML tags. So, if you have: pFoo!/p when you look at $Element-hasChildNodes() for the p tag, you will get true, and $Element-childNodes-length is equal to 1, even though Foo! isn't an HTML tag. Interestingly though, when you iterate through the tree, you get the p tag as one of the elements, but you never get a text-only element that has that p as a parentNode. In fact, get_class($Element) always returns DOMElement, even on the text-only nodes, which I would have expected to be DOMText elements...but I guess not. So I'm wondering why $Element-hasChildNodes() would return true, but iterating through the DOM tree returns no elements that have that $Element as a parentNode. What's more, looking at $Element-childNodex-length isn't too helpful, because, for example: h2a name=bar/aFoo/h2 returns two child nodes, neither of which has Foo for its textContent.

Re: [PHP] 4.1.1 Causes Signal 11 On FreeBSD 4.5 / Apache 1.3.22
I am experiencing a lot of Signal 11's when I compile PHP 4.1.1 into my Apache server on my FreeBSD 4.5-RC machine. If I compile the -exact- same Apache configuration with PHP 4.0.6, it works fine. As soon as I switch to 4.1.1, it causes Signal 11's (and sometimes 10's) when I load certain pages. It seems that it crashes when the pages have mySQL database access on them and are fairly complex (I was thinking perhaps a memory problem?) You somtimes get 10's? That's a SIGUSR1 and not something that will take down your server. It would actually cause a graceful restart of Apache, but I don't see how anything we do in PHP could cause spurious sig10's. Get a backtrace of one of the sig11's. Without that there isn't much hope of us tracking this down. No, it doesn't take the server down. It kills one of the child processes off and apache starts a new one. And yes, it's sig 10's and sig 11's interchangeably. I re-complied everything from scratch to make sure it's not a glitch and I get the same results now. How can you backtrace something? I'm not a C developer, so I don't really know what you're talking about.

[PHP] Problems Installing 4.1.1 on FreeBSD 4.4 STABLE
Hello Everyone. I just tried to upgrade my Apache 1.3.22 web server to us PHP 4.1.1. I was running PHP 4.0.6 without problems for months, but wanted to take advantage of the bug fixes and new features. The compile seemed to go OK, and the new httpd runs fine. However, I've encountered a strange bug when visitng my web sites using Netscape 4.78. Whenever you visit a page that uses PHP's mySQL capabilities extensively (in my estimation, anything that has an update query, but I've only confirmed this on a handfull of pages so it could be some other more subtle symptom), the httpd process that handles that request gets a signal 10 or signal 11 (it switches back and fourth, but it's mostly a signal 11). When you go to these pages in IE or any other browser, it works fine with very few exceptions - it has been found to sig10 or sig11 on a few requests from IE or other versions of Netscape, but not with any regularity. Netscape 4.78 causes it to crash every time. It's important to not that it does not happen with every request or on every site - most pages operate fine, even with updates. It just seems that the few that do cause it to crash have several selects/updates on one page. Has anyone else experienced this problem? Here's a list of the versions of things that I'm running: Apache 1.3.22 PHP 4.1.1 (4.0.6 works fine) mySQL 3.23.46 mod_ssl 2.8.5 OpenSSL 0.9.6a Any help would be greatly appreciated. Thanks.
