I have a quiz site which randomly shuffles and puts together multiple choice questions. The correct answers (as well as some other data) are stored in session variables, and the students' answers are sent via POST. On the page that the quiz form submission links to, the correct answers in SESSION are compared to the POST data, and the results of the quiz are displayed. The site used to work just fine, so I have no idea what happened to make it suddenly stop working.
I have checked to see that the session_id is the same on both pages and it is. I have made sure that start_session() is placed appropriately above all the HTML (and have even confirmed it by calling var_dump($_SESSION) on the first and second page, user login variables are displayed, but nothing else).
Here is the code from "startquiz.php" which assembles the quiz form. The session variables in question are just after the end of the "DISPLAY A QUESTION LOOP"

I apologize for posting the entire code for each page, but I'm not a professional programmer and I'm not sure what is relevant and what isn't.
The problem has been resolved. It turns out the issue was with the php.ini file on the hosting site. They recently made some changes that I was unaware of and the temporary storage location for session files/variables became undefined. Once I edited that information in the .ini file, everything worked just fine.
I'm trying to change this below script that will works and save same file but inside server internal location instead of like it is doing now save file and then upload to my destination.

I am trying to convert xml node into array, i have 3 separated nodes inside parent match node, so i need to convert all them into array.
When i try this code
foreach($lineup->away->player as $player){
$awaysquad .= $player->attributes()->name . '; ';
$matcharr['name'] = (string)$player->attributes()->name;
$matcharr['number'] = (int)$player->attributes()->number;
$matcharr['playerid'] = (int)$player->attributes()->id;
$yellowcount = count(explode(" ",$player->attributes()->booking));
if(substr_count($player->attributes()->booking,"YC") == 1){
$matcharr['yellow'] = (int)$player->attributes()->id;
}
elseif((substr_count($player->attributes()->booking,"RC")==1)
or ($yellowcount == 3)){
$matcharr['red'] = (int)$player->attributes()->id;
}
}
and call this matcharr by:
print_r($matcharr);
There is just last element for each index/array, i want to get all players from lineup tag.
So print_r prints this:
Array ( [goal] => 2456166 [name] => Luís Leal [number] => 9 [playerid]
=> 2474225 [yellow] => 2486288 [subin] => 2353344 [subout] => 0 [minute] => NA )
for each match tag, but i need to get 22 players for each match.
Here is more detailed code:
foreach($week->match as $match){
$matcharr = array();
//var_dump($match);
$fixid = 0;
if($match->attributes()->id == 0 || $match->attributes()->id == ''){

I was needing to divide the resulting links into three columns to fit my html layout.
We accomplished this by changing the numbers in the code marked with "// <---- here".
Because the amount of links returned could be different each time, I am trying to figure out how to change those numbers on the fly. I tried using
$number_a = mysql_num_rows($result);
$number_b = $number_a / 3;
$number_b = ceil($number_b);
$number_c = $number_b - 1;
and then replacing the numbers with $number_b or $number_c but that doesn't work. Any ideas?
As mentioned before, you can use the mod (%) function to do that.
Basically what it does is to get the remainder after division. So, if you say 11 % 3, you will get 2 since that is the remainder after division. You can then make use of this to check when a number is divisible by 3 (the remainder will be zero), and insert an end </div> in your code.
Here is a simplified example on how to use it to insert a newline after every 3 columns:
$cycle = 1;
$arr = range (1, 20);
$len = sizeof ($arr);
for ( ; $cycle <= $len; $cycle++)
{
echo "{$arr[$cycle - 1]} ";
if ($cycle % 3 == 0)
{
echo "\n";
}
}
echo "\n\n";
