The in_array function works inconsistently

Hi,

The in_array function sometimes malfunctions on my computer yielding
the error message shown below. The code shown below usually works, but
sometimes doesn't. This even happens with the same instance of code.
Different results on different times I load the same page. Can anyone
explain what's going on here?

Best wishes,

Mountain Man

Warning: in_array(): Wrong datatype for second argument on line 1.

if (in_array(Yes, $like)) { $like2 = Yes; }
elseif (in_array(No, $like)) { $like2 = No; }

Hi Mountainman,

What excactly is Yes and No?
Didn't you mean a variable $Yes or a string "Yes" ??

Hi Erwin,

I meant a string "Yes."
