I am using in_array() to search for a value ("other"), in order to validate
a form.
If I pass $_POST["interests"] as the array to search PHP says that it is an
invalid datatype.
It is an array and if I copy it to another variable (i.e. $list =
$_POST["interests"];) it works fine.
The same is also true of implode().
Do you believe this is intended or is it a bug?

$_POST['whatever'] isn't an array $_POST is an array, but yes you will
have to make it into an array first using something like
$data = explode(",", $_POST['interests']);
then it's an array.

$_POST['whatever'] _can_ be an array. The OP said it was.
Consider:
<input type="checkbox" name="whatever[]" value="one">
<input type="checkbox" name="whatever[]" value="two">
<input type="checkbox" name="whatever[]" value="three">

Are you sure it's an array? Use var_dump, or is_array to check.
Is it produced by a series of input elements named "whatever[]" (note the use
of [] - required for PHP to produce an array)?

Yes, it is an array, I used is_array and var_dump at the suggestion of
others, but I am wondering why it doesn't work as $_POST["interests"], but
it does as $list (if $list = $_POST["interests"] -- it should be exactly
the same). It is an array due to what you suggested to Cameron (checkboxes
with a name of "something[]")

If it is verified by *is_array* that $_POST["interests"] is an array,
then i guess you must be sending arguments in wrong order.
Please verify the syntax of *in_array*:
bool in_array ( mixed needle, array haystack [, bool strict] )
post a sample code if it still not solved.

You can not trim an array. If you enable the notice errors, (a good
practice to catch errors during development) you will get an error
from PHP Parser.
In your case the $val will be converted to string and trim function
will return a string value "Array".
Modify the lines with:
foreach ($_POST as $key => $val)
{
if(!is_array($v al))
$_POST[$key] = trim($val);
}
// Validate form
// Do other checks here
if (in_array("othe r", $_POST["interests"]) && $_POST["other_explanat ion"]
== "") { $err = true; }
// Compress listing arrays
$interests_list = implode(", ", $_POST["interests"]);

Even with your suggestion on trim() I get the warning. Confirmed in_array()
args are in the correct order.
