foreach not assigning variable values

[woodgnome]

Hello,

I'm submitting an html form to a php script and want to assign values to variables in order to do a database update. I have always used this in the past with the $_POST array (in this case the array is coming fromTinyAjax):

foreach ($ary as $key => $value)
{
$$key = addslashes(trim($value));
}

This works as expected if all the $key names are unique. However the form has multiple rows (generated by php) as follows:

<tr><input name="code[0]" /><input name="description[0]" /></tr>
<tr><input name="code[1]" /><input name="description[1]" /></tr>
<tr><input name="code[2]" /><input name="description[2]" /></tr>

and so on. This produces an array like:

[code[0]] => OWNER
[code[1]] => MANAGER

and so on.

When I try to access the variable $code[0] it doesn't exist, but
echo "$key : $value"; gives code[0] : OWNER etc.

It seems as though the assignment of the value in the $$key = $value does not work for a key with an index[].

Has anyone any ideas what I'm doing wrong??

Thanks

its a multidimensional array

foreach ($ary as $key => $value)
{
	if(is_array($value)){
		foreach($value as $key2 =>$value2){
		$$key2 = addslashes(trim($value2));
		)
	}else{
	$$key = addslashes(trim($value));
	}
}

you will have to do something about name clashes
