PHP - Need Some 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...

$bookingID['$row['id']'] = $row['id'];
echo $bookingID['$row['id'];'];

Parse error: parse error, expecting `']''

What would fix this?

I've spent many hours trying to solve this with no success. So, here's my challenge.
Sample Data from DB:
Month   Year           Measure
5           2010         164
6           2010         31
7           2010         20
8           2010         10   
9           2010         10
10         2010         10
12         2010         10
1           2011         10

I need to display this data in a chart, but notice that I don't have data for month 11 and the chart must show all months with data and the month that I don't have data for (11 in this case) will show an interrupted line.
I need to put this into an array to display month/year as label and measure as chart value.
So, the above data needs to become:
Month   Year           Measure
5          2010           164
6          2010           31
7          2010           20
8          2010           10   
9          2010           10
10        2010           10
11        2010           --
12        2010           10
1          2011           10

The issue here isn't the chart, but how to add the missing month (11) to the array and keep the measures corresponding with their months.

Thank you.

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.
