PHP - Help With Arrays

I'm not sure if this can be done, but I would like to get the sum for each $.row[''] result ex: if $row['robotics'] had values of 100,150,300 I would like to be able to show a total of 550

Code: [Select]
<?php
echo "<Table border=1>";
echo "<tr><td></td><td>Robotics</td><td>Chiral Stuctors</td><td>Enriched Uranium</td><td>Mechanical Parts</td><td>Coolant</td><td>Consumer Electronics</td><td>Precious Metals</td><td>Reactive Metals</td><td>Oxygen</td><td>Toxic Metals</td></tr>";
$result = mysql_query("select * from `pi`");
while ($row = mysql_fetch_array($result)) {

echo "<tr><td>".$row['pilot']."</td>";
echo "<td>".$row['robotics']."</td>";
echo "<td>".$row['chiralstuctors']."</td>";
echo "<td>".$row['enricheduranium']."</td>";
echo "<td>".$row['mechanicalparts']."</td>";
echo "<td>".$row['collant']."</td>";
echo "<td>".$row['consumerelectronics']."</td>";
echo "<td>".$row['preciousmetals']."</td>";
echo "<td>".$row['reactivemetals']."</td>";
echo "<td>".$row['oxygen']."</td>";
echo "<td>".$row['toxicmetals']."</td></tr>";

}
echo "</table>";

Hello! i want to store data in a array (as seen in the code). Im trying to make it so that a php code search through the arrays and find the correct one. once it does it tells me. I dont know if im close, How ever this is what i have.


$carrier = $_POST['carrier'];

$carriers = array(
array("verizon","tmobile","sprint","att","virgin","textnow","metro","unknown"),
array("@vtext.com","@tomomail.net","@messaging.sprintpcs.com","@txt.att.net","@vmobl.com","@textnow.me","@mymetropcs.com","@teleflip.com")
            );

If ($carrier = 

Ok i am trying to create a simple program that will allow mwe to use an array with 8 numbers, the output form should show the numbers in their original order that the user inputs them, in numerical order, Highest number, lowest number and then the average number. I am confused on what logic i would use to do this. If anyone could help me get started it would be much appreciated. here's waht i have so far.
Code: [Select]
<?php
$Num1 = $_POST['fielda'];
$Num2 = $_POST['fieldb'];
$Num3= $_POST['fieldc'];
$Num4 = $_POST['fieldd'];
$Num5 = $_POST['fielde'];
$Num6 = $_POST['fieldf'];
$Num7 = $_POST['fieldg'];
$Num8 = $_POST['fieldh'];
$Numbers = array(1,2,3,4,5,6,7,8);
$big = max($Numbers);
$small = min($Numbers);
$average = array_sum($Numbers) / 8; 
?>

Hello,

I have 2 array questions that I'm hoping someone can help me with.

1) First, I'm trying to add elements to a previously existing array.  I start with:

$data = array('text' => $_POST['text'],

   'question_type' => $_POST['question_type'],

  'solution' => $_POST['solution'],

  'filename' => $filename,

   'author_id' => $_POST['author']);
Then, under certain circumstances, I'm going to want to add the following to the array $data:

      'incorrect_solution1' => $_POST['incorrect_solution1'],

'incorrect_solution2' => $_POST['incorrect_solution2'],

'incorrect_solution3' => $_POST['incorrect_solution3'])

I tried the concatenation function, combined with an if statement but then PHP thinks that I have a string.

2) Once I have the array, I want to shuffle the solution and 3 incorrect solution indices.  I'm not sure how to shuffle just a portion of an array.

Any help with either or both questions would be appreciated.

Thank you.

Let's say I have an array like this:

Man1(0), Man1(1), Man1(2), etc.
Man2(0), Man2(1), Man2(2), etc.
Man3(0), Man3(1), Man3(2), etc.
...

and I want to loop through the array.
I know I can do:
Code: [Select]
$i=0;
while $i<=99
{//...do something with Man1[$i];}
i++;
but can I also do a loop with each Man?
Like:
Code: [Select]
$i=0;$a=1;
while $i<=99
{//...do something with Man$a[$i];}
i++;a++;
I've written all the code for each Man separately and I'm thinking there's got to be a way to shorten the code with another loop, but I don't know how.
Hope that makes sense.
Thanks.

I am trying to learn about sorting and modifying arrays and I am practicing on a book assignment but need some help to grasp what I need to do.

If you go here, you will see how it is supposed to work.

http://198.86.244.3/mabarckhoff/WEB182/ch11_ex1/

I need to write a case to sort the task when you click the sort button and modify when you click that button. The delete button works and the add task works. I understand the sort array and have added that case, but don't know how to get it to work with the submit. Also there is a promote button so would need 'promote' what ever you have chosen in the dropdown menu to the top.

Here is my code.

Hi, I am trying to specify a new variable that points to two columns from a table, I think I need to use an array but not sure how to code it. The reason I want one variable instead of two is because it will be used as a dynamic link for home teams and away teams to link to the team page, hope that makes sense. Here is the code I currently have:

Code: [Select]
<?php
$query = "SELECT tr.competition, tr.date, tr.htp, tr.hts, tr.ats, tr.atp, tr.et, tr.htpts, tr.atpts, tth.team as hometeam, tta.team as awayteam
FROM test_selections ts 
LEFT JOIN (test_results tr, test_teams tth, test_teams tta) 
ON (tth.teamid = tr.hometeam AND tta.teamid = tr.awayteam)
WHERE ts.userid = '{$_SESSION['userid']}' AND (tr.hometeam = ts.teamid OR tr.awayteam = ts.teamid)
GROUP BY tr.resultid
ORDER BY tr.resultid DESC";
        $result = mysql_query($query) or die(mysql_error());
        
        while($row = mysql_fetch_assoc($result))
{
$team = array($row['hometeam'], $row['awayteam']);
?>
Any help would be very much appreciated.

Ok so this link returns HTML

$hitlist = file_get_contents($iMobLink."get_hit_list?user_id=".$iStore[2]."&level=10&auth_key=".$iStore[3]);

now to parse it out I have this

$entry = explode('<entry>', $hitlist);
$hitlist = file_get_contents($iMobLink."get_hit_list?user_id=".$iStore[2]."&level=10&auth_key=".$iStore[3]);
    $user_id = explode('<user_id>', $hitlist);
$user_id = explode('</user_id>', $user_id[1]);
$mobname = explode('<mob_name>', $hitlist);
$mobname = explode('</mob_name>', $mobname[1]);
$paiduser = explode('<paid_user>', $hitlist);
$paiduser = explode('</paid_user>', $paid_user[1]);
    $amount = explode('<amount>', $hitlist);
$amount = explode('</amount>', $amount[1]);
$paid_time = explode('<placed_time_ago>', $hitlist);
$paid_time = explode('</placed_time_ago>', $paid_time[1]);
$level = explode('<level>', $hitlist);
$level = explode('</level>', $level[1]);
$entry = explode('</entry>', $entry[1]);
echo $user_id[0]."\n";
echo urldecode($mobname[0])."\n";
echo $amount[0]."\n";
echo $paid_time[0]."\n";
echo $level[0]."\n";
echo $entry[0];}

Notice there is more than one energy.. now how to I parse it out to where I can define each entry by a variable or something... any help is appreciated.. Thanks

I can't work out the quotes around this...

Hi,
I'm having some trouble trying to generate my random string for a name.
This is my code:
Code: [Select]
<?PHP
 function rand_string( $length ) {
$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";

$size = strlen( $chars );
for( $i = 0; $i < $length; $i++ ) {
$str .= $chars[ rand( 0, $size - 1 ) ];
}

return $str;
}
 
 $salt_string = rand_string( 5 );
 
 $test = "1234";
 
 echo "salt_string = $salt_string";
 echo "<br>";
 echo "test = 1234";
 echo "<br>";
 $array = array('$test', '$salt_string');
 echo "<br>";
 echo "array = $array";
 echo "<br>";
 $imploded = implode($array);
 echo "<br>";
 echo "imploded = $imploded";
 
 ?>

And it returns:

salt_string = 8pbAe
test = 1234

array = Array

imploded = $test$salt_string

I don't understand why my imploded variable is not 12348pbAe

Hello,

I have an array, $solutions, and a separate indexing array, $solution_order.  From the $solution_order array (developed from the $order variable, where each $order variable looks like '0321' or '3021'), I'd like to create a new array $ordered_solutions, which indexes on the values picked from the $solution_order array.  For example, if my $solutions array is (Big, Small, Fat, Skinny) and my $solution_order array is (2,3,1,0), then the final results should be (Fat, Skinny, Small, Big).  I've written down what I have so far.  Any thoughts about how to move this forward would be appreciated.

Thanks!
function GetOrder($solution, $wrong1, $wrong2, $wrong3, $order) {

$solutions = array( $solution,

               $wrong1,

$wrong2,

               $wrong3);

$solution_order = array(substr($order,0,1),

       substr($order,1,1),

       substr($order,2,1),

      substr($order,3,1));
$ordered_solutions = array();

//what do to here??

return $ordered_solutions;
}

I have ticket's for my lottery system.

Somone chooses 3 random numbers out of 36, it will show

1|20|30

but now I want to beable to have my Members BUY multiple Tickets! So then I added a comma between the 3 arrays


So the code will look like this when they select the balls they want

Code: [Select]
1|20|30,20|10|5 /etc /etc

But now I have 1 problem.

How do I go about validating the arrays for each COMMA inside the | ARRAY?  Cause let's saY I don't want anyone  to Submit a ball number higher then "36" how would I go about making it so it checks through each array and if it's higher then 32 I can give them a Error?

Also, I each Ticket costs (5 Forum Gold) so the above code would be a total of 10 Forum Gold, because they're "2" Tickets being bought, how would I go about making a $counter++ in the arrays to count only the "," so I can tell how much Gold the member needs to have before he purchases

Thanks

Hi,

I need to do this:
Write a method to quickly find the array index position of a given number in a ascending sorted array of numbers. e.g. in an array { 1, 2, 5, 10, 102 }, the array index position of a given number 5, would have an answer of 2. We're looking for an answer that's better than O(n).

I was using php's built in methods but I need to do this with a basic function using no helper methods.

Can anybody help me out with this?

Thanks in advance.

Hi Guys,

I have an array Code: [Select]
$arr
When i run this function Code: [Select]
print_r($arr)
I get the output below:-

--------------------------------

Code: [Select]
Array
(
    [WHMCSAPI] => Array
        (
            [ACTION] => getclientsproducts
            [RESULT] => success
            [CLIENTID] => 87
            [PID] => 13
            [DOMAIN] => dfgbhcgnd.com
            [TOTALRESULTS] => 1
            [STARTNUMBER] => 0
            [NUMRETURNED] => 1
            [PRODUCTS] => Array
                (
                    [PRODUCT] => Array

                            [CUSTOMFIELDS] => Array
                                (
                                    [CUSTOMFIELD] => Array
                                        (
                                            [NAME] => IP Address
                                            [VALUE] =>
                                        )

                                )

                            [CONFIGOPTIONS] =>

                        )

                )

        )

)
---------------------------------

My question is, how can i print only certain parts of the data rather than printing the whole array. For example i only want to echo the values for [NAME], [USERNAME], [PASSWORD] and [NEXTDUEDATE] from the [PRODUCT] part of the array

Thanks in advance
