implode function not working

[gannina]

I first posted this in the javascript forum, but it turned to be a php problem. When I try to implode the $myarray I get an "Array to string conversion" error. If I change my array in the implode function to myarray2 it works. How can I get the implode function to work with myarray? I'm not sure why it doesn't work with that one, thanks.

$x = 1;
while($row = mysql_fetch_array($subcategory)) {
        $subid = $row['subid'];
        $subcat = $row['subcategory'];
        $myarray[$x] = array($subid, $subcat); 
	$x = $x + 1;
} 
print_r($myarray);
$myarray2 = array('test', 'test2', 'test3');
print_r($myarray2);
?>

<?php 
$test = implode(', ', $myarray);
echo($test);
 ?>

$myarray2 works fine as it's a regular array with 3 elements however $myarray is a multidimenSional array.
The correct way to do this is:

$str = "";
for($i=0; $i<count($myarray); $i++){
     $str .= implode(", ",$myarray[$i]);
}
print $str; #or whatever. 

Cheers!

I tried cutting and pasting your code but it gives me the following error

Undefined offset: 0 in C:\WebSite\tutform.php on line 49

Warning: implode() [function.implode]: Bad arguments. in C:\WebSite\tutform.php on line 49

I found out what the problem was. I set the first array at x=1, and your code started at 0, since array(0) didn't exist it caused that error. Thanks for the code I can finally implode stuff
