[Resolved] Printing an Array

[terrym]

I'm trying to get an array to print (echo) but cannot get it to work. The script goes something like this:-

if (something){

while ($row = mysql_fetch_array($display)) {

(Put the array values into variables each time round)
$id = $row["id"];
$question = $row["question"];
$opt1 = $row["opt1"];
$opt2 = $row["opt2"];
$opt3 = $row["opt3"];
$opt4 = $row["opt4"];
$answer = $row["answer"];

(Put the variables back into a different array to use later on)
$quiz = array(
'id' => $id,
'question' => $question,
'opt1' => $opt1,
'opt2' => $opt2,
'opt3' => $opt3,
'opt4' => $opt4,
'answer' => $answer);

Then I print this new array and it works fine.

} else if {

It is in this section that I want to print the quiz array, but I haven't managed to achieve that yet. Below is just one of the latest efforts:-

for ( $xx = 1; $xx < 16; $xx++ ){
echo "$xx >";
echo " $quiz[$id] ";
echo " $quiz[question] ";
echo " $quiz[opt1] ";
echo " $quiz[opt2] ";
echo " $quiz[opt3] ";
echo " $quiz[opt4] ";
echo " $quiz[answer]<br>";
}

}

I expect it is something quite simple, but I cannot find the answer so far. So any guidance would be greatly appreciated.

Well, given the flow of your code $quiz will never be created when you want to print it. Here is how your code reads:

1. If $something
   1.1 Loop over database results
   1.2 Build $quiz array
   1.3 Print $quiz array
2. If not $something
   2.1 Print $quiz array

Now only 1 or 2 can execute at any given time so you can't have 1.2 execute if 1 isn't true. Thus $quiz won't be built if you just go right into 2. My guess is that you want to do something like this:

while ($row = mysql_fetch_array($display))
{ 
   //(Put the array values into variables each time round) 
   $id = $row["id"]; 
   $question = $row["question"]; 
   $opt1 = $row["opt1"]; 
   $opt2 = $row["opt2"]; 
   $opt3 = $row["opt3"]; 
   $opt4 = $row["opt4"]; 
   $answer = $row["answer"]; 

   //(Put the variables back into a different array to use later on) 
   $quiz = array( 
   'id' => $id, 
   'question' => $question, 
   'opt1' => $opt1, 
   'opt2' => $opt2, 
   'opt3' => $opt3, 
   'opt4' => $opt4, 
   'answer' => $answer); 

}

if ($something)
{ 
   //Then I print this new array and it works fine. 
} 
else if 
{ 
   for ( $xx = 1; $xx < 16; $xx++ ){ 
   echo "$xx >"; 
   echo " $quiz[$id] "; 
   echo " $quiz[question] "; 
   echo " $quiz[opt1] "; 
   echo " $quiz[opt2] "; 
   echo " $quiz[opt3] "; 
   echo " $quiz[opt4] "; 
   echo " $quiz[answer]<br>"; 
} 

This code loops over your database results and builds your $quiz array before it goes into your if statement and does whatever you need to do there.

Ohh yeah and the code you posted shouldn't work because you have your {} in the wrong order.

Thanks eoghain. What can I say? If I say anything at all, I'll probably only shoot myself in the foot again?
Thanks again.
