I've been developing something on my home server, and noticed something weird...

Does using the Header() redirect end Session variables or something? Cause mine aren't being carried over from my login script to the main page (after login).

Suppose I have an associative array that looks like this:
$arr['alpha_1'] = 'some value';
$arr['alpha_3'] = 'some value';
$arr['alpha_4'] = 'some value';
$arr['beta_2'] = 'some value';
$arr['beta_4'] = 'some value';
$arr['beta_6'] = 'some value';
$arr['gamma_1'] = 'some value';
$arr['gamma_5'] = 'some value';
$arr['gamma_6'] = 'some value';
$arr['gamma_7'] = 'some value';

Let's assume that the array is reasonably large (hundreds of entries).

Is there an efficient way of getting all the items whose key starts with 'beta'? (without doing a foreach/strncmp loop?)

Thanks in advance!

P.S: The array is not sorted.

Is there a way to convert xhtml formatted documents as a document/rich text file or a pdf on the fly?

I have looked at htmldoc, but it does not support css in the current release and even in the upcoming 1.9 release, only CSS1 tags are supported and not the positioning tags.

What I am looking to do is create my resumé in an xhtml 1.0 or 1.1 document and be able to have it convert to word or even pdf. All the agencies that have been contacting me have requested a doc format of my resumé. I have a doc (and pdf) version, but I hate having to do double entry and then save to pdf. I could save as html in OO.org, but I hate doing that. I like the clean xhtml resum&eacue;.

My resumé can be found here. Already, there is a revision difference on the technical resumé. Also, the non-technical version is not offered up in doc and pdf. I have searched quite a bit and fond services, but they are using the aforementioned htmldoc toolkit. There is a lot of hits on rtf to xhtml, but not vice versa. Thanks for any help you can give.

I'd like to set up a service that sends SMS's to my customers, and is capable of receiving messages back from them (i.e. replies for invitations). I've tried a bunch, but I can't seem to find a reasonable service. Can someone recommend a good one (for the USA)?

Here are services I tried: 
1) Teleflip. Free, but reliability is terrible. 
2) SimpleWire. Want $800 to set up an evaluation license.
3) Clickatell.com wants $1700/month for a shortcode, and says that without a shortcode, there's no way to get 2-way messaging in the US with them. 
4) SMSXchange.com is almost, almost perfect - everything works, no crazy setup fees... Just the messages that they receive from the cell phones can be in no way correlated to what was sent in the original message (i.e. I dont' know which invitation my user is responding to - there can be several outstanding invitations per user). 

Any advice?

Whats the best way to secure a PHP driven (Image Board) script that doesn't require login/password to use?
The admin section (using combo of cookies/session controls for login, and hashes)?

I know there is a way to do this, but i'm at a loss to remember what it is. Given a PHP file is there an easy way to format it into HTML for nice display? Ideally with line numbers added. I want to be able to write code to help analyze my PHP source code.

How could I enable a site to receive SMS messages and post the contents to a blog of sorts (similar to LJ's text-message posting)? I understand how this would be done with email, but SMS is strange to me. I assume there's a program out there that listens in on the same protocol used by SMS, then does whatever with the data once it's received. My hackerish idea of rigging a cell phone up with an unlimited messaging plan then writing a Perl script to gank messages from it would probably work, but it won't scale up nicely :).

I'm open to purchasing a product to just drop onto my server, but I have no idea where to begin. If someone could point me in the right direction (tutorials to do it myself or a product to purchase) I'd appreciate it! Thanks.

I am just putting the finishing touches on a year long project that included in its design the use of an Op-Cache of some sort. After spending the last week and a half slamming a dev. server with siege for testing I noticed that occasionally the apache2 would seg. fault. We're using the LTS version of Ubuntu 6.04 with a stripped down environment dedicated and slaved to Apache w/memcache. From what I've researched and tested, this is actually a pretty well known issue with APC and also xcache. I've already written a simple daemon to watch the primary error log and if it spots a segfault fault error report to restart Apache, but this feels like using a band aid on a compound fracture.... Anyone have any other suggestions?

PHP compiled with just the bare minimums plus memcache, mysqli & mysql, JSON, and the XML library.

OK - my group is finalizing a website and we have a convoluted form ... and when we moved it from our server to the end clients we started getting the error:
Warning: Invalid argument supplied for foreach() in /usr/local/www/vhosts/mtrinc.com/htdocs/mirror/inquiry_handler.php on line 112

Here is the relevant code

$section = array();
$labels = array();
$message = array();

foreach ($_POST as $key => $val)
    {
    $section[] = $key;
    foreach ($val as $tit => $dat)
        {
        $labels[] = $tit;
        $message[] = $dat;
        }   
    }

Anyone have any ideas?

i'm new to php (and this community) and just started taking an intro to php class to improve my skills. anyway, i made a mistake in some of my code at one point i wrote...

$counter = $counter++

to increment one instead of just...

$counter++

well, i had this going with a while() statement and it didn't work because $counter wasn't being incremented because $counter = counter++ isn't correct. but why is that? it still should increment, right? if you write $counter = $counter++ in the c language (well, with the appropriate syntax, as my instructor tried) it works just fine. he couldn't find any post of this php bug either. any thoughts?

I’m getting better with my sanitization, thanks to all the help here.

Now I wonder.

I’m combining a muti-page php form into a single (hopefully cleaner) php file. 

Normally I would sanitize and check user rights on every single page. 

(output from the form is dependent on individual rights of the user stored in a DB)

I want to protect against injection, and my gut says I should simply place the sanitization function and user rights verification at the top of the page….but I wonder if it should be placed at the top of every switch case. 

Thoughts?

Thanks All…!

(I’m going to start helping an actual php programmer with a side project of his…I'm sure to learn a lot, so hopefully I’ll be able to stop asking so many questions, and start helping to answer a few.  I appreciate everyone’s generous help!)

In a follow up to pkbarbiedoll’s recent post….

I’m not sure how to learn what the (I think they are called) “special characters” and syntax used in the post.

I was able to find what \s means (and subsequently \t \n \r \0 and \xOB )
From

switchstatement’s reply and link.

 

But how would find all of these (special characters?)…to be able to decipher and use?

• Is there a list somewhere?
• What wording should I use in a search?

I know I’m completely lame…but I saw this somewhere in a sanitize string…and I’m lost

'/(;|\||`|>|<|&|^|"|'."\n|\r|'".'|{|}|[|]|\)|\()/i'

I'm trying to push PHP5 OOP to the limit, and it's breaking instead of bending :) What am I doing wrong? 

Here's what I'd like to do - 

class Message {
   public static function getMessageType() {
     return self::MY_CONSTANT;
  }
}

class IncomingMessage extends Message {
   const MY_CONSTANT = "a"; 
}

class OutgoingMessage extends Message {
   const MY_CONSTANT = "b";
}

class Message {
   public static function test() {
     return self::getMyConstant();
  }
  
  public static function getMyConstant() {
   return "0";
  }
}
class IncomingMessage extends Message {
   public static function getMyConstant() {return "a";}
}
class OutgoingMessage extends Message {
   public static function getMyConstant() {return "b";}
}
echo OutgoingMessage::test();
