[PHP] sorting arrays
Hello List I've looked at array_multisort( ), but it doesn't seem like the right function. Here's an example of my array, it's a listing of CD reviews: $cds=array(array(Lowest of the Low, 20050105,9,Toronto), array(Heavy Blinkers,20041020,6,Chicago), array(Apple,Fiona,20050308,5,Seattle)); If I wanted to sort them alphabetically, no problem, just sort($cds). If I want to sort them by date (the second item in the array) or by ranking (the third), how do I do that? Is there something simple? Many thanks.

Re: [PHP] Javascript Question
I would do two things. 1. Test your print() function on the same frame. Create a div called printableText and see if you can print it. If that works, then your print() function is okay. 2. Test your targeting. Use a different function, such as trying to change the text or rollover an img in another frame. Then use the document.path that worked. BTW, I don't think parent is high enough. And if anyone knows of a Javascript newsgroup this discussion should be on, I would join it too. - Original Message - From: GodFoca [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, June 07, 2004 8:47 AM Subject: [PHP] Javascript Question Hey! Sorry for the OT, but since there seems to be no js newsgroup in gmane, I thought maybe someone in here could answer this simple question. I am trying to use javascript's print() to print a frame FROM ANOTHER frame. This is the layout: frameset rows=*,40 frameborder=NO border=0 framespacing=0 frame src=... name=pritableText frame src=... name=printButton scrolling=NO noresize /frameset In printButton I have a simple anchor: a href=# onClick=parent.printableText.focus(); parent.printableText.print(); Yet nothing happens.

Re: [PHP] Simplistic PHP tutorial
I've looked at the php.net tutorial, and though I'm learning some things from it, it's still a bit over my head. It seems to presuppose a comfort level with programming which I do not have. Can anyone recommend a simple, hand-holding, introductory tutorial suitable for someone with no programming experience to speak of? Personally, if I was teaching someone programming concepts from scratch I would start them with Javascript. It's mostly platform-independent, you don't need to install any software, and you don't need to upload your files to a server that has PHP installed. Most of the basics (functions, variables, math) are the same in php, perl, flash, and Javascript, and Javascript is the simplest one in terms of getting started and testing your code quickest. There are some differences, of course, but you'll always be double-checking your syntax anyway. I like the PHP book from Wiley. And MySQL/PHP Database Applications from MT Books. For Javascript, buy the cheapest, oldest used book you can find. Or Inside Javascript from New Riders.

[PHP] xml ignore whitespace
Howdy Here's where I'm at. $DomDocument = domxml_open_file(myFile.xml); $RootDomNode = $DomDocument-document_element(); print_r($RootDomNode); // just to test $listItems = $RootDomNode - child_nodes(); print_r(brthere are . count($listItems). child nodesbr); // 35! print_r($listItems); When I run the above, it pulls in my XML file and counts how many childNodes there are, then displays them. What I want to do then is run a for loop on the childNodes, but ... I want to ignore the whitespace nodes. In Flash there's an ignoreWhite function, is there anything similar in PHP? I've poked around a bit, and it doesn't look like it. Thanks for your time. Gabino -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] regular expressions php/perl/actionscript
Hello
I'm wondering if Regular Expressions are the same in Perl and PHP (and
possibly Actionscript)? They look the same and smell the same, but if I see
a book in a store for Perl Regular Expressions that's $10 cheaper than the
PHP one (is there one?), then is it the same thing?
While we're on this topic, I'm looking to find an attribute in an XML and
replace it with a string variable I get from a form.
I can use:
$bgClrOld = preg_match('/backColour/',$s); // 1
to find the attribute, but how do I find and replace
backColour=a3b4c5
with
backColour=$bgClrNew
?
TIA
Gabino

Re: [PHP] regular expressions php/perl/actionscript
I forgot to mention that in my XML file, inside the quotes in this attribute
backColour=xx the x's will be variable..., so I need some kind of
wildcard to select everything from backColour + the next 8 or 9
characters, cuz it might be backColour=333990 or whatnot.
'backColour' will be a unique string in the XML file, but I'll have those
quotes and a variable RGB hex value to find and replace.
Can I do something like
$bgClrOld = ereg_match('/backColour/'+8chr,$s);
?
Merci

Re: [PHP] regular expressions php/perl/actionscript
Thanks for the suggestions. Between the online manual and the books I have I
think I'll get there eventually. Sometimes my logic just sux. What I needed
to do was have the user fill out a form and if they make changes to the XML
file I would update the file. So, my long way around was to go through the
old XML file and create a string variable for every possible form field.
Then I would compare the /bgClrOld/ to /bgClr/ and if they were different I
would then update the file with an ereg_replace.
After some poking around, this seems to be the way to go. Only if the field
is not empty so I change it
if ($bgClr !=){
$bgClr=xx;
}
I still have some work to do, but ...

[PHP] transformation to htm file when downloaded
Hello All I'm just starting to get PHP, and I'm wondering about the security of the code I write. It _seems_ that when I try to download the PHP file directly (like using Save Target As...) it will download only as an HTML file and my PHP code is gone. I've tried this on a few other people's sites, and this seems to be the common behavior. Is there a way someone can extract my php file without this transformation? What are some good security issues I should know? One of the things I'm starting with is a simple blog/guestbook. I have a couple form fields and I strip_tags ... what else should I be doing? I want to leave the guestbook pretty open, so I don't want a sign-in and confirmation thingie. I don't even mind anonymity, cuz I can edit the comments later if I want. Thanks for your time.

Re: [PHP] transformation to htm file when downloaded
GT seems to be the common behavior. Is there a way someone can extract my php GT file without this transformation? In a nutshell - no. Not without your server being compromised (i.e. hacked into or misconfigured). GT One of the things I'm starting with is a simple blog/guestbook. I have a GT couple form fields and I strip_tags ... what else should I be doing? I want GT to leave the guestbook pretty open, so I don't want a sign-in and GT confirmation thingie. I don't even mind anonymity, cuz I can edit the GT comments later if I want. Check for SQL injection possibly? (assuming you are even using SQL) and make sure you addslashes (or test to see if that is being done for you) and that's about it. Depends how anal you want the script to be though :) I mean you could check everything.. from strings to integers, to string length, to IP address (flood control), to duplicate entries, etc etc etc. Really a how long is a piece of string scenario here. Hey Richard, Thanks for the quick response. I'm thinking of adding a check for the string length, so someone doesn't copy and paste a dictionary into my guestbook, but I'm not looking at flood control because the comments might be somewhat conversational. I have a couple PHP books (like the PHP Cookbook, PHP: Read Less, Learn More) and a couple PHP/mySQL books and I can't seem to find anything about that transformation. Are there other books that describe what actually happens? Is that on php.net somewhere, and what kind of keywords should I use to find it? I don't think transformation is the right word. Also, perl has strict, which is to prevent other people from running your scripts from their server. I added strip_tags to prevent someone from running code on my server. Have I got my a** covered?

Re: [PHP] transformation to htm file when downloaded
If you are saving to SQL you can limit this from the SQL end as well as the PHP code, but it's worth doing at the PHP level too. By contraining the size of the string to tiny or whatever, right? I could also use Javascript, but I like that PHP is more of an invisible hand. I'm not using mySQL yet, that's the next step. Some other day. I'm using PHP to modify the original guestbook.html page, and for now because I don't expect a lot of comments, I prefer the quick access. No using PHP to access a sleepy database and finding the contents to fill the page and then display it. I just don't need that level of performance yet. Maybe when I need a second page of comments, but I don't want these comments to get carried away. It's more a luxury item to comment on an editorial written on my magazine. I'll have to get into mySQL when I start storing and saving more DB info, a catalog of some sort, saving a user's log-in and settings, but it seems like overkill for this tiny bit of functionality. I presumed that if someone ran my file.php from the server that there would be some kind of transformation to render the tags before they are displayed. I find it fascinating that just moving the file off the server to your hard drive with something like Save Target As... manages to do the same transformation. That's one of the things I don't like about Javascript... it's so open to scrutiny. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
