PHP - Chat Box Confusion

Ok I have this form with 6 fields that the user enters a geocaching code.  In the database I have a table called cacheinfo.  There are 6 enteries in the database in this table. Now Im trying to confirm that each field entered matches the right geo code.  I have it working but I feel that its a very bad way of doing it my way. 

can someone please show me a better way as I have other situations I do something simliar and its just getting silly.  Here is the code;


if(isset($_POST['nextbtn'])){
$cache1 = trim($_POST['cache1']);
$cache2 = trim($_POST['cache2']);
$cache3 = trim($_POST['cache3']);
$cache4 = trim($_POST['cache4']);
$cache5 = trim($_POST['cache5']);
$cache6 = trim($_POST['cache6']);

$cache1 = mysql_real_escape_string($cache1);
$cache2 = mysql_real_escape_string($cache2);
$cache3 = mysql_real_escape_string($cache3);
$cache4 = mysql_real_escape_string($cache4);
$cache5 = mysql_real_escape_string($cache5);
$cache6 = mysql_real_escape_string($cache6);

$FetchCache = mysql_query("SELECT * FROM cacheInfo WHERE cacheInfoID='1'") or die('can not find cache information');
$cache1 = mysql_fetch_array($FetchCache);
if($cache1 !==$cache1['cacheCode']){
$url = "/register-cache.php?error=true";        
header("Location: $url");  
}


$FetchCache = mysql_query("SELECT * FROM cacheInfo WHERE cacheInfoID='2'") or die('can not find cache information');
$cache2 = mysql_fetch_array($FetchCache);
if($cache2 !==$cache2['cacheCode']){
$url = "/register-cache.php?error=true";        
header("Location: $url");  
}


$FetchCache = mysql_query("SELECT * FROM cacheInfo WHERE cacheInfoID='3'") or die('can not find cache information');
$cache3 = mysql_fetch_array($FetchCache);
if($cache3 !==$cache3['cacheCode']){
$url = "/register-cache.php?error=true";        
header("Location: $url");  
}

$FetchCache = mysql_query("SELECT * FROM cacheInfo WHERE cacheInfoID='4'") or die('can not find cache information');
$cache4 = mysql_fetch_array($FetchCache);
if($cache4 !==$cache4['cacheCode']){
$url = "/register-cache.php?error=true";        
header("Location: $url");  
}

$FetchCache = mysql_query("SELECT * FROM cacheInfo WHERE cacheInfoID='5'") or die('can not find cache information');
$cache5 = mysql_fetch_array($FetchCache);
if($cache5 !==$cache5['cacheCode']){
$url = "/register-cache.php?error=true";        
header("Location: $url");  
}


$FetchCache = mysql_query("SELECT * FROM cacheInfo WHERE cacheInfoID='6'") or die('can not find cache information');
$cache6 = mysql_fetch_array($FetchCache);
if($cache6 !==$cache6['cacheCode']){
$url = "/register-cache.php?error=true";        
header("Location: $url");  
}
// If all match now run the rest of my code......
}

I am very confused at an example in a book I am reading called Beggining PHP regarding XML-RPC requests. I will write the code below:


function send($remoteServer, $remotePort, $fullXMLRPCRequest) {
     $headers = '';
     $data = '';
     $socket = fsockopen($remoteServer, $remotePort);
     fwrite($socket, $fullXMLRPCRequest);
     while ($str = trim(fgets($socket))) { // why doesn't this exhaust the returned call??
          $headers .= $str . "\n";
     }
     while (!feof($socket)) {
          $data .= fgets($socket);
     }
     fclose($socket);
     return $data;
}



The question I have is notice how there are two while statements and they both access the same resource ($socket). So how can there be two while statements?? Wouldn't the first while statement exhaust the resource and there would be nothing on the second while statement? I hope this makes sense. It's sort of like saying while(x < 10) { //execute... ++x; } then another while statement while(x < 10) { //execute... ++x; }

Well then wouldn't the second while statement not execute? I hope I made sense.

Thanks for all the help in advance. Obviously knowing XML-RPC would help in answering this question, hopefully most of you are familiar with it.

why does

Code: [Select]
while($random_user_TOTAL_COUNT <= 15 && $random_user_INFO = $random_user_USERS->fetch_object()){
work, but

Code: [Select]
while($random_user_INFO = $random_user_USERS->fetch_object() && $random_user_TOTAL_COUNT <= 15){
doesn't.

why???

I'm sure this is something simple that I'm just overlooking right now, but it's got me very frustrated and I just want a quick fix...

I have 2 arrays, $data_old and $totals_old   Let's say each looks like this (with the 123456 being different for both): 

Array
(
    [2014] => Array
        (
            [123456] => Array
                (
                    [EMPS] => 114350
                )
        )
)

When I merge the two, I get something like this: 

Array
(
    [2014] => Array
        (
            [0] => Array
                (
                    [123456] => Array
                        (
                            [EMPS] => 114350
                        )
                )
            [1] => Array
                (
                    [60] => Array
                        (
                            [EMPS] => 1470
                        )
                )
        )
)

How can I avoid the [0] and [1] and just have those be [123456] and [60], without referencing the 123456 and 60? 

Hi,

I am writing a script for invoicing various contractor jobs.

I have fields for date assigned and date completed. Both are timestamp with timezone columns in a postgresql table

My goal is to have a cron job which selects the records from the table on the dates the invoices are due and includes the proper jobs-- i.e. the ones that are completed prior to the due date and time(5PM on the first and 15th of each month)

That is where I am running into confusion as to how to store the time/tz and then select it in the future so everything is correct

This is what I have right now:

Code: [Select]
$assignmenttype, "miles" => $miles, "notes" => $notes, "dateassigned" => "{$assignmenty1}-{$assignmentm1}-{$assignmentd1} $time1:00 America/Chicago", "datecompleted" => "{$completedassignmenty1}-{$completedassignmentm1}-{$completedd1} $time2:00 America/Chicago");
    $res = pg_insert($conn, 'assignments', $invoicearray);

hey,
I started creating this page that is suppose to upload pdf files, it opens the file upload box but when i click to submit the file nothing happens. I have checked the folder and no file goes in it. I don't know what i am doing wrong.

Can anyone help please?

After reading the PHP guide that actually seems way more useful then online tutors.
Im starting to see why PHP is confusing me now. My way of thinking is way off on how the script reads stuff.

when I read this code I think the output should be Bob
cause echo reads $foo which equals bob and thats the end of it.
but the output is actually My name is bob

can someone please help me understand the error of my thinking in how this works. would be most appreciated.

Code: [Select]
<?php
$foo = 'Bob';              // Assign the value 'Bob' to $foo
$bar = &$foo;              // Reference $foo via $bar.
$bar = "My name is $bar";  // Alter $bar...

echo $foo;                 // $foo is altered too.
?>

Hi

$feed_url = "http://www.foo.com/feed/";
$xml = simplexml_load_file($feed_url);
foreach ($xml->channel->item as $item) { 
$ns_content = $item->children('http://purl.org/rss/1.0/modules/content/');
$title = $item->title; // This is title
$desc = $ns_content->encoded; // This is description
$category =""; // Here i am stuck, how can i get category associated with this feed
}


How can i see its category, i see in source code it looks like this and even categories have sub categories which looks same, i wants categories names to display wihich is associated with feed:

<category><![CDATA[Health]]></category> 
<category><![CDATA[Men]]></category>

Hi, I'm a PHP beginner using Julie Meloni Sams Teach yourself to help me.
My confusion is with this script
<?php

$file_dir ="/path/to/upload/directory" ;

foreach($_FILES as $file_name => $file_array)
{
echo "path: ".$file_array["tmp_name"]."<br/>\n" ;
echo "name: ".$file_array["name"]."<br/>\n" ;
echo "type: ".$file_array["type"]."<br/>\n" ;

echo "File name is" . " ". $file_name ;


}
?>
What I don't understand is the foreach statement

foreach($_FILES as $file_name => $file_array)
$_FILES is an associative array, right? So $filename should represent the key id  and $file_array the value.
but she is using the $file_array as if it is an array and accessing the values with associative index which confuses.
I mean, let's say I declared a normal array.
$array = array("Sarah" => "Jane", "John Smith") ;
if i wanted to use a foreach loop i would do it like so
foreach($array as $fname => $surname)
{
 echo $fname  ;
   echo $surname ;

}
$fname will print the first name and surname surname.
I didn't use an indices to access the values.

foreach($_FILES as $file_name => $file_array)
can someone explain this to me? Thanks

This topic has been moved to MySQL Help.

I'm fairly new to this and I have looked around but I can't find much information on it. Basically I know what an array and a function is but I'm currently working through an oop login and register sytem and I am seeing this quite a lot:   function myFunction($myVariable = array()){   $Firstvariable = $myVariable[0]; $Secondvariable = $myVariable[1];   //etc   }   This is really confusing me and I can't see any examples in any tutorial sites or books of an array and a function being used like this. Can someone just explain how something like this would work in simple terms? I have also checked the manual but I can't see an example an array being used like this. Any help would be much appreciated. Thanks.

I am not sure how I should go about doing this. I have a server that has a chat server on it, people register an account and then have access to this chat server from their application. To initially connect to it, they need a game id and game stamp (kind of like a username/password for the game). I don't want chats from one application to display in another users application. When I created this chat server it was for another purpose, and could only support about 64,510 different chats since each chat ran on its own port. For my current purpose it is a little different some applications can have 1 - 10 chats going at once per user using the application. Say their is 100 people using the application and each is using 5 - 10 different chat windows. With 100 users on at the same time all chatting, that can get up to 1,000 different ports being used. I don't want that, because say there are 100 applications also using chat, that is about 100,000 different ports, and I am pretty sure you cant have 100,000 ports. So! I need a way to make a chat server, any ideas on how I could do this with my php?

need more information? please ask!
