help with an error in a testing script phptest (search_array)

hello all and thank you all so much ahead of time for any help.. I am using a old, unsupported testing/quiz script called phptest. My webhost is telling me since they switched me to the new servers they are getting errors in their php logs about 2gigs a day from my scipt.. Now.. I prob had the error on the old servers but they prob didnt log or didnt notice it..

Is it normal for webhosts to have logging on in php? I would say that they would have a lot of errors from all the domains...

ok so here is the error they sent me

[11-Aug-2006 19:08:08] PHP Warning: array_search(): Wrong datatype for
second argument in
/hsphere/local/home/jonathan/rescueexams.com/firetest/question.php on line

[11-Aug-2006 19:08:57] PHP Warning: array_search(): Wrong datatype for
second argument in
/hsphere/local/home/jonathan/rescueexams.com/firetest/question.php on line
126

So I opened up question.php and here is lines 125-134

php Code:

Original - php Code

       // figure out which question number we are on.
        $question_number = array_search($question_id, $test_session->questions);
        // we need to compare types using the '===' comparison operator because array_search() can return
        // 0 for the index which evaluates to false using the normal '==' comparison operator
        if ($question_number === FALSE) {
            pt_exit('Fatal Error: unable to determine question number.');
        }
 
        // output test title and additional notes
        echo "<div class="form"><center><h2>{$test_session->info['description']}</h2></center>";

as you can see this is line 126
$question_number = array_search($question_id, $test_session->questions);

so do you need more info to diagnos the issue?
I dont seem to be having any issues as far as testing is concerned but who know for sure..

can this line safely be removed?

Any ideas?

I am migrating towards another testing script and I am looking at moodle right now any other suggestions for a feature rich script would be great.!

THANKS SOOO MUCH

ALSO.. here is the whole code in the file question.php
this is all the code from the file above called question.php with the line 126 problem

hope this helps and if anyone needs more please tell me.. it doesnt seem like anyone is helping me on this here but i hope it will turn around..
