Partly shuffle php array

Hi,

I have an array $quest


for ( $count = 0; $count <= 99; $count++)
{
$quest[$count]=mysql_fetch_array($result,MYSQL_NUM);;

}

$quest is a 2d array.For instance

$quest[0][0] contains a question
$quest[0][1] to $quest[0][5] each contains an answer choice for the question
only one of which is correct.

I want to randomly shuffle all the answer choices($quest[0][1] to $quest[0][5]) but let the question remain at $quest[0][0]).How can I do that?
I know there is a function called shuffle() but shuffle(),shuffles the entire array.I just want to shuffle all elements of a particular array except for the first one.



Thanks

Thats true, but you can limit the shuffle excluding 0 so it will be 1-5, something like this, might help:

<?php

$quest[0][0] = "Question";
$quest[0][1] = "Answer 1";
$quest[0][2] = "Answer 2";
$quest[0][3] = "Answer 3";
$quest[0][4] = "Answer 4";
$quest[0][5] = "Answer 5";


echo $quest[0][0];

$answer = range(1, 5);
shuffle($answer);
foreach ($answer as $answer) {
    echo "<br />",$quest[0][$answer];
}

?>

PHP:

Will echo out:

Question
Answer 2
Answer 1
Answer 3
Answer 4
Answer 5 

Code (markup):

 

You can try this..

<?php

$_quest = $quest;
$quest = array();

foreach($_quest as $idx=>$q){
  shuffle($q);
  $quest[$idx] = $q;
}

?>

You should really modify the code that builds the array to begin with if you can. This however, will work with an existing array.

<pre><?php

$quest = array(
	array(
		'Question One',
		'Answer 1:1',
		'Answer 1:2',
		'Answer 1:3',
		'Answer 1:4',
		'Answer 1:5',
	),
	array(
		'Question Two',
		'Answer 2:1',
		'Answer 2:2',
		'Answer 2:3',
		'Answer 2:4',
		'Answer 2:5',
	),
);

foreach($quest as &$_quest)
{
	$q = array_shift($_quest);
	shuffle($_quest);
	array_unshift($_quest, $q);
}

print_r($quest);

?></pre>
