My personal favorite for projects at work is Eclipse with phpEclipse plugin and at home I use vim almost exclusively. I recommend Zend Studio if you can afford it since it has a GUI for both Windows and Linux, and it runs fairly fast for being a Java application. ;) I agree with Mike, pretty much anything is better than FrontPage for editing web pages. If you're going to be changing both HTML and PHP, Zend works fine, but if you want something with less features but with all the important stuff such as syntax highlighting, multiple window buffers, and all that shebang, go for EditPlus www.editplus.com or UltraEdit www.ultraedit.com, I prefer EditPlus over most such simpler editors on Windows, and on Linux I use Jed, which has good menu handling and Windows-like shortcuts that speed up the work. I tend to get slightly confused when working 95% in Windows and then having to edit something in vim or emacs.

It's also going to be very confusing for users seeing the Acrobat toolbar floating in the middle of their page. It would be interesting to see some tests of PDF-in-iframe done in various different browsers, but unless it just happened to work perfectly in every common browser (we can all dream, can't we?) I wouldn't touch it. Jasper After some consideration I am pretty sure it works, since an iframe/ is just the same as a frame/, and I am dead certain you can open a PDF document, or a Word document, or a Flash file, inside a frame without anything crashing. As for the PDF toolbar, I think that with the proper CSS styles on the iframe/ element you can make it pretty apparent that the iframe/ contains a PDF document. Also, when using iframe/ you are weeding out those old browsers that wouldn't support even loading an iframe/, which means that you get relatively new browsers, and those should all support this method. Besides, if this is for an editor interface, for a specific client, one could reasonably demand that they use at least one of the newer browsers such as IE5+ or Mozilla.

I believe in customer choice. For that matter, *I* probably don't use a browser that does this right, being as I'm usually on Linux, almost always on Netscape, and very very very rarely do PDF and/or Flash work really right for me. And you know what? I very very very seldom care badly enough about any of the content I'm missing and when I do care enough to go get it, I'm disappointed by the content more often than I'm pleased that I took that effort. Again, this is obviously MY weird world-view at work here. :-) I wasn't trying to advocate you doing something you don't want to do. If you consider the feature worth implementing, weighing the options, you implement it, or you don't, either way, your choice. I merely stated that it does work, when using a recent browser. The iframe/ tag was added in IE3+ which is pretty darn old, and if you've seen ANYBODY using anything Microsoft-made prior to IE3 in your server logs of late, let me know. :) The following major browsers have support for iframe/: Internet Explorer for Macintosh: 5.2 (not sure about 5.1) Internet Explorer: 3.0 and above Mozilla: 1.0 and above Netscape Navigator: above 4.0 (which should be 6.0) Opera: 4.0 and above Safari: 1.0 and above So, if you use one of these browsers, and considering that you rarely (I'd say about %1-5) see people using anything below these versions, you'd be safe adding an iframe/ if you wanted to. If the browser does not have support for iframe/ it will ignore the tag and it won't break anything at all. As Jason Karns showed in the example from cstv, and you could test that on all your different browsers and see what happens, if they have the plugin installed, it ought to work... But, on that note, if it is entirely vital to display the PDF, why not convert the PDF to HTML instead and display that then? Would work in all browsers, a little hit on the server performance, which can be avoided by caching the results of a PDF - HTML conversion. Don't ask me where to get code for this, as I have no clue, but I am sure it exists somewhere.

Strato offers PHP 3.x, 4.0.x, 4.3.x and 5.0.x in parallel. Perhaps you should think about outsourcing your hosting *g*. I am assuming they're running PHP through CGI in this case, am I correct, or are they hosting on Windows to achieve the multiple PHP versions? If CGI, that rather affects performance of larger applications, it especially impact render time of more complex templates and forms. During my own testing we gained lots of time by just running it as a compiled Apache module instead of through CGI and in .htaccess. On our hosting servers we solved it by running a compiled PHP 5 Apache module on one server, and regular on the others. This way, if someone requests PHP 5, they can be put on the server that supports it, and if somebody wants to switch server from PHP 4 to PHP 5, it's an easy enough task.

No problems that I can think of as long as you use a custom php.ini file to avoid such things as safe_mode, max_execution_time, and various other nasties that you might bump into if you run it on various servers. I was said that using Perl script is more suitable for such task since PHP scripts have problems with sending large amount of mail. Bah humbug. PHP CLI works just fine, and, it is quite easy to do both ncurses and text positioning/coloring for both Windows and Linux, and it is a lot easier to run it either from the web or shell. It's not the PHP script that has the problem, in reality, it's just an issue of making sure that you're sending the mails in batches, which you can do if you make sure that there's no maximum execution time set for the PHP script. Is that true or not? Any success/failure stories? It is false. And, I am sure that someone can dig up a success story, but, I know for a fact that I'd rather use PHP for sending large amounts of email, especially if there's to be MIME parts and or HTML included in it.

Kevin Wang wrote: Hi All, My php5 web application needs to parse/marshall a bunch of large xml files into php5 objects at the beginning of handling each request. These xml files are static across all the requests and it is really time consuming to parse/marshall them into php5 objects. I am wondering if there is any means to cache these xml objects so that each request will not go through the same time consuming xml parsing/building operation. Serialization doesn't work in my case as deserialization is also very expensive. I am using Apache as the web server. What I am thinking is that if php5 allows us to keep certain objects (and their references) around across all the requests in a child process instead of cleaning all the object memory every time after a script/request is finished. I guess this problem is quite common for any large and complicated php applications. If I had XML files that large, I would either switch database engine to MySQL or PostgreSQL since that way I can page/load the data quicker than parsing an XML document, or, I would consider the following: Does the XML data change a lot? If not, why not cache the actual HTML output instead of the data? That way you get n number of HTML documents instead of one dynamic script, these files would only change when the XML file has a changed filemtime(), and, it's easier for the server to handle the requests. Take a look at: http://pear.php.net/manual/en/package.caching.cache-lite.php Cache_Lite is actually quite powerful since it allows you to cache either the entire finished output, or just a part of the site and render that from cache until the data has changed. You could write down a whole series of cached documents either from one request, or by running a cron under Linux or scheduler task under Windows, and one user wouldn't get the brute of the waiting time when it renders the cached parts.

The (...) was just an illustration if you had an if statement that
didn't fire, then $return_array wouldn't be defined at all. Just put
$return_array = null; in the top of the script somewhere so that it is
defined at all times, that way you don't have to worry about the actual
notice about it not being defined.
You can then also make a simple check to see if it is an array, for
instance:
if (!emtpy($return_array) is_array($return_array)) {
/* Code to do something with $return_array */
}
That would be a good idea if you for instance are going to iterate the
items in the array somewhere, if you don't check first, you might
attempt to iterate a variable that doesn't contain an array but null,
then PHP will yell at you for that.
You are welcome to mail the script to me privately and I can take a look
at it for you.

I researched on internet and found that this is some kind of trojan which infects the *.index files. It penetrate from HTTP. Some paople were saying that there is vulnerability in PHP. Please help how can I protect my server from further attacks. Hello Shafiq, One very common culprit in this scenario would be phpBB, especially older versions, and if you are running PHP without safe_mode and include_path directives, a script could very well overwrite every world-writable (or web server writable) file on your entire server. Happened to us once after a client had been running an old phpBB version. We now have a set of scripts in place that scan our servers for vulnerable scripts, phpBB among those, and alerts us when they're found in a client's home directory. So, to protect your server: turn on safe_mode. If clients (if you have clients on the machine) request safe_mode to be turned off, you can do that manually in httpd.conf for Apache (not sure about IIS on Windows). Also, using hard include paths in the httpd.conf for each virtual host will prevent the scripts running on a site from including/touching files that are outside said paths unless they manage to run a shell with a PHP script that can be activated without using php.ini, which might in this case be another security hole.

Well, if you do a count of the root, you ought to get the amount of numbers in there, and, with that number of the last item, access that array, do a count() on that, get the last item, and so forth and so on, you could write a small recursive function here to call itself with each new child, getting the last item, down into the structure until X level. Not sure if there's a PHP native function for doing this, though. Perhaps someone else knows. If nothing else, try this way.

I've compiled php from source, during which process I set --with-config-file=/etc. Once the compile completed, I then copied php.ini-recommened to /etc/php.ini. After restarting Apache, I run phpinfo() and Configuration File Path is showing only /etc, which means it's not find /etc/php.ini. So then I tried the cli and ran phpinfo() from it and same thing. If I run it as php -c /etc/php.ini, it can find/read it. For what it's worth, this is happening on a Gentoo system, but this shouldn't make too much of a difference since I've compiled PHP from source (v5.0.4), the same source I've used on a couple of other (non-Gentoo) machines.

I think that --with-config-file-path is an absolute path to the php.ini file, and not just a directory name, although, it ought to default to php.ini, but perhaps when setting that directive it assumes that you are specifying a custom configuration file, for instance /etc/php5_alt.ini or /etc/my_php.ini instead of just php.ini. So, I think you should use the --sysconfdir directive instead if you just want to specify where PHP has its ini file.

[PHP] Migrating PHP4 to PHP5 (WAS: 'God' has spoken... :-))
Miles Thompson wrote: The problem with PHP 5 is that the ISP's have to be so conservative. There's no tagging mechanism which says process these files with PHP5, use PHP 4 for everything else. That would be so wonderful. Just to be able to set what PHP .so to use based on VirtualHost/ or Directory/ in Apache would be bliss. Under Windows it's easier, of course, since you have specific configurations for each virtual host in IIS. I've tried running the CGI version of PHP5 on a PHP4 system, and of course it works, but it's slower than molasses in January. So, based on experience, better to move early than later. I suspect a jump from PHP4 to PHP6 will be huge -- the problem is to move the ISPs. A lot of ISPs run some form of enterprise Linux, or it could be just a control panel, that is dependent on the RPM version of PHP, which in most cases is still stuck arond 4.3.x somewhere, except in those cases where the ISP has taken the law in their own hands and compiled PHP from scratch, overwriting the RPM version, and hoping that this will not break anything too seriously when the control panel tries to upgrade itself the next time. ;) Others use scripts that are encoded with either IonCube or Zend, and are thus forced to stay with PHP4 since their software vendor hasn't made the leap yet. For instance, when encoding with Zend Encoder for PHP4, you can get some pretty nasty errors when running under PHP5. If the software vendors could make the leap RIGHT NOW and convert their godforsaken software to PHP5 and release two versions since there'll hardly be any difference in the code, we'd be a long way already. It's all mostly related to the encoder in these cases, for instance Zend. That's the way we do it with one of the applications I've written, it's shipped both as PHP4 and PHP5 Zend encoded, as well as IonCube encoded.

[PHP] XSL namespaces and callbacks
Hello,
A while back I posted a question in relation to XSL namespaces and
callbacks, but never got a response, not even a flame, which I found a
bit odd for this list. :P I know this is pretty cutting-edge for PHP
since the XSL library has only been used in PHP 5, well, except for the
XSLT/Sablotron that was available for 4.
My original post can be found here:
http://marc.theaimsgroup.com/?l=php-generalm=112299671816888w=2
What I am trying to do here is what the .NET framework does in XSL by
adding a custom namespace that binds to an Assembly and a class. Is this
at all possible in PHP? The reason why I am asking this is because I do
not want the end user to be able to execute any type of PHP code through
XSL, which they can if I call $xslt-registerPHPFunctions(); and enable
the php namespace through
xsl:stylesheet version=1.0
xmlns:xsl=http://www.w3.org/1999/XSL/Transform;
xmlns:php=http://php.net/xsl;
For security reasons I would want to limit the user to a specific custom
library class instead of allowing them to use the php:function() that
can call any PHP method/function/internal.
So, instead of:
xsl:value-of select=php:function('ClassName::Method', ./@id)/
I would like the call to be:
xsl:value-of select=namespace.classname:Method(./@id)/
Where the stylesheet declaration looks like:
xsl:stylesheet version=1.0
xmlns:xsl=http://www.w3.org/1999/XSL/Transform;
xmlns:namespace.classname=urn:namespace.classname
Since that way they can only call the macro classes/methods that have
been validated and added as libraries when loading the XSL renderer.
Any help in this matter is greatly appreciated. Also, if somebody can
forward this matter to the PHP internals, Jochem comes to mind, it would
be awesome. I think this would definitely be a very competitive feature
for the PHP XSL implementation.
Warm Regards,
Torgny

These notions of logging EVERYTHING is sometimes worse than actually allowing the culprit script to run slowly or execute lots of queries. 4 GB of logfile says way less than actually reading through the script and checking to make sure that the queries are proper. If you are still intent on logging these queries, I would go with your logs_table idea and limit the fields and field lengths to the extreme and index it tightly to make sure that it does not grow too much in size, that means, char or varchar, and definitely no text/blob fields. If this is a web script, one idea would be to only trigger the logging for a specific set of IP numbers, so that only your own browser triggers the logging, but it is left dormant while others browse.

The easiest way to do this is to keep all the select option items in an
associative array and iterating this with foreach or for to output the
option/ elements. That way you can directly check the value of each
option to detect which was selected.

That would be the idea, yes. It was some time since worked with

Btw yes it must be checked when user submit this. But If it's possible
client option on rule, would be better.
I am not sure about this, is there even client-side validation support
in Quick_Form? Haven't really looked into this. I would suggest writing
a manual javascript evaluation for the specific fields that should be
visible when the checkbox is checked, or to have a postback between. The
JavaScript option sounds most tempting, since it makes it a bit more
user-friendly. That way you can use the JavaScript alert() function to
present the fields that have erroneous information as well as altering
styles in the fields in question to perhaps have a red border to
indicate errors.

Most times it's instantaneous, but sometimes it can hang. I want to

Generally, using include or file_get_contents() for a remote call is a
Bad Idea. Perhaps if you used curl instead? You have a lot more control
over the entire call that way. Of course, the curl code might be a bit
bulkier in PHP, but I find it works quite well.
As for fsockopen(), it works just like a file pointer.
http://www.php.net/manual/en/function.fsockopen.php
That manual page gives a pretty good description of how to use it.
Idea: The socket will by default be opened in blocking mode. You can
switch it to non-blocking mode by using stream_set_blocking().
The last parameter to fsockopen() is the timeout for connecting to the
socket, and the manual describes it as such:
Note: If you need to set a timeout for reading/writing data over the
socket, use stream_set_timeout(), as the timeout parameter to
fsockopen() only applies while connecting the socket.

[PHP] XSL custom xmlns/urn in PHP5 for callbacks
Hello,

version=1.0
xmlns:xsl=http://www.w3.org/1999/XSL/Transform;
xmlns:myapp.library=urn:myapp.library
exclude-result-prefixes=myapp.library
xsl:output method=html/
xsl:param name=currentPage/
xsl:template match=/xsl:value-of
select=myapp.library:ClassMethod('arg1', 'arg2')
disable-output-escaping=yes//xsl:template
/xsl:stylesheet
Hope someone can help here. If not possible, I can always use the
standard PHP function/class::method callbacks, but it would be nice to
have custom xmlns so that I could add several different libraries.

Re: [PHP] Error Suppression with '@'
Hello Justin, I would guess that this is mostly performance and memory related. When, for instance, trying to iterate an array, or a directory with files, using @ on all function calls, it will attempt to go through the array, attempting to allocate memory for each item, but when finding it empty/broken, it leaves the loop and goes on to the next statement in the code. From what I can tell, PHP handles memory efficiently, although I wouldn't hazard this when deploying a larger site using this type of approach. Especially if the code inside a larger if..else block was performed on an object that was created with @function() call, and then all the consecutive calls to functions operating on that object also used @. This would take up both CPU time and memory, possibly creating leaks, based on how efficiently PHP would handle the operations on a non-existant object. A rule of thumb is to instead use empty() and is_array() and such functions to discern if the object you are going to handle indeed is of the type you wish it to be, that saves you both time and effort when trying to debug something in the future. The empty() function goes a long way here, unless dealing with integers, since empty() will return true if the value is 0, which might not be desireable. I hope this helps you in your argument against your fellow developer. :] Regards, Torgny Justin Burger wrote: Good Morning, I was having a discussion with a fellow PHP Developer this morning and he mentioned that he put's an '@' sign in front of all function calls, and every time he accesses an array; I know that this is sloppy, and dangerous, but I don't know exactly what this exposes him to, can any one give me any real world examples of why this is bad, so I can relate it to his code? php.net does not have much information about this.

Re: [PHP] Converting integer type to long
Wee Keat wrote:
The problem is, I have not been able to convert PHP's integer/float type

The reason why is because there's no real long support in PHP.
But, since you mention a value such as 0.01, you are not looking for a
long, you are looking for a float. So, what you need to do is to
type-cast all the values involved in the making of the variable that
holds the float value.
For instance:
$var = (float)$var1 / (float)$var2;
$query = sprintf('%.2f %s', (float)$var, $string);
I haven't found the exact points where PHP forgets it's a float, but
it's always good to make sure all mathematical operations are performed
on the value as a float by type-casting, otherwise it might lose
information.
