[PHP] using pg_query in a function not working

[Marc Fromm]

I have to sql statements in functions to use in my code. Even though the echo 
statements show the sql is valid the sql does not seem to execute and I get the 
error, "PHP Warning:  pg_fetch_object() expects parameter 1 to be resource, 
boolean given in . . . line 154 . . ."
Line 154: while($val = pg_fetch_object($student))

##############################

Function Calls:

$insert = recordSentList($empid, $list, "printed"); // No record gets inserted 
into the table

$student = getStudent($list);
while($val = pg_fetch_object($student)) //No records get listed
{
