"Fatal error: Cannot use object of type userModule as array in /hermes/web01/b2180/" .

These kind of fatal errors happen very very early in a programs development.


Make sure the module 'userModule" is available and in the proper directory on the new server.

if you read the log file it should give u a line # where the code is ref. then debug it from there.

or post your code for the given error.

The error "Cannot use X as array" means that you are attempting to access an index of a non-array object. Arrays are something you should typecheck for. There are a few ways to deal with it:

1. The easy way: Only send arrays to the function.
2. Typecast objects (generally only stdClass objects work) or scalar data (i.e. strings, integers, etc) to arrays.
   
   i.e.

   function foo($bar) {
       $bar = (array)$bar;
       ...
   }

3. Restrict the accepted type of the function to array (this can only be done for arrays and objects).
   
   i.e.

   function foo(array $bar) {
       ...
   }

4. Check that the data you are handling is an array beforehand. Generally if your function accepts non-arrays, you should have another means of handling them.
   
   i.e.

   function foo($bar) {
       if (is_array($bar)) {
           ...
       } else if (is_scalar($bar)) {
           ...
       } else {
           ...
       }
   }

note: depending on what array functionality you use, there are some Interfaces that enable objects to do that.

- for using in foreach() you can implement the Iterator or IteratorAggrega te interface

- access objects like an array ($obj["prop"]) use the ArrayAccess interface

- for some of the array functions, appropriate interfaces are available (e.g. Countable for count())
