Question 1:

<?php
$i = 5;
$i = 5 + $i++;
echo $i; // What does this print?
?>

Question 2:

Which of the following is wrong? (There may be more than one
which are wrong.)

* in_array($needle, $haystack);
* stristr($needle, $haystack);
* strpos($needle, $haystack);
* preg_match($needle, $haystack);

Question 3:

Describe the output of this code:

<?php
function print_defined_vars ()
{
print_r(get_defined_vars());
}
$a = 1;
