copy 2d php array to 2d javascript array

I have a 2d (two dimensional,2 dimensional) php array that I want to copy to a 2d javascript array.The 2d php array is $quest[100][6] and the 2d javascript array is questions[100][6] . I have written the javascript code inside the <?php....?> itself using echo "<script language="javascript" type="text/javascript">.......</script>;


Now ,inside the javascript,when I try to copy the 2d php array to the 2d javascript array using the following method it works

questions[0]= ["<?php echo join("\", \"", $quest[0]); ?>"];
questions[1]= ["<?php echo join("\", \"", $quest[1]); ?>"]; ... and so on


However, if I try to do the same using the following method it does not work
for (var i= 0; i <= 99; i++)
{ questions= ["<?php echo join("\", \"", $quest); ?>"]; }

Why is that?What mistake am I making?Any help will be deeply appreciated.Thanks



-------------------------------------THE CODE----------------------------------------------
<?php


Access database and store result of mysq_query in $result.......
$result = mysql_query($query);


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

}

echo "<script language="javascript" type="text/javascript">

var questions = new Array(100);
for (var i = 0; i <100; i++)
{ questions = new Array(6); }



/*The following method of copying 2d php array to 2d javascript array is not working
for ( var i = 0; i <= 99; i++)
{ questions= ["<?php echo join("\", \"", $quest); ?>"]; }
*/

/*The following method ,however,is working*/
questions[0]= ["<?php echo join("\", \"", $quest[0]); ?>"];
questions[1] = ["<?php echo join("\", \"",$quest[1]); ?>"];
questions[2] = ["<?php echo join("\", \"",$quest[2]); ?>"]; ....and so on




</script>";


mysql_close($db_server);

?>

 

I don't know about your code above, but you should be using single quotes, so change your echo from

echo "<script language="javascript" type="text/javascript">
//and this
</script>";

PHP:

to this

echo [COLOR="Red"][B]'[/B][/COLOR]<script language="javascript" type="text/javascript">
//and this
</script>[COLOR="Red"][B]'[/B][/COLOR];

Hi,
In case,it is difficult to figure out the mistake with my code,can someone tell me,any other method to copy a 2d php array to a 2d javascript array.Thanks

 

Here's my approach:

<?php

// view in plain text
header("Content-Type: text/plain");

// create a 2d array with random numbers in it
for($i = 0; $i < 10; $i++) {
   for($j = 0; $j < 10; $j++)
   $arr[$i][$j] = rand( );
}


// write js
$js_arr = "<script type=\"text/javascript\">\nvar arr = new Array( );\n";

for($i = 0; $i < 10; $i++) {
   // write a 2d js array declaration
   $js_arr .= "arr[$i] = new Array( );\n";
   for($j = 0; $j < 10; $j++)
   // write a js array
   $js_arr .= "arr[$i][$j] = \"" . $arr[$i][$j] . "\";\n"; // this is the general idea
}
$js_arr .= "</script>";

echo $js_arr;
?>

Rainulf your approach was quite nice.

here is how I would go about it:

Simply change $array to the variable of the array.

<?
header("Content-Type: text/plain");
if($array == null){
echo'<script type="text/javascript">
var arr = new Array( );
';
}
//some stuff will need to be changed
$data = $array; //change array to the variable of the array
//now we find array size

$amt = count($data);
$amt2 = count($data[0]);
$amt3 = count($data[1]);
$i = 0;
$k = 0;
while($i < $amt) {
$j = 0;
   while($j < $amt2){
   echo"arr[".$i."][".$j."]=\"".$data[$i][$j]."\";\n";
   $j++;
   }
$i++;
}
?>
</script>
