how to suppress foreach error?

I am trying to keep some code from popping out a foreach error if the array does not exist? I keep getting this error:

Code:
Warning: Invalid argument supplied for foreach()
Help?

Ok, there are a few ways.. Ideally you should declare the variable an array before you use it for anything:

Code:
$arr = array();
But if for whatever reason you cannot do that then:

Code:
if (is_array($arr)) 
{

###  Foreach
