DB-Intro-PHP-HW.docx CSCI 3343 Initials ______Page | 11
If this lab is an Individual assignment, you must do all coded programs on your own. You may ask others for help on the language syntax, but you must organize and present your own logical solution to the problem. No lab is complete until the student submits the signed pledge form associated with that lab. I realize that no coded programs will be graded until I turn in the sign & pledge form associated with that program; any late penalties will continue to compound until the pledge form is submitted.
If this lab is a team assignment, both team members may share logic as they program side by side on their own computers. Each person must type all of his/her own code as part of the learning process. Team assignments are never to be “You do this portion and I’ll do that portion” or “You do this lab and I’ll do the next lab”.
Some of the lab assignments will have short answer questions. These short answer questions will be spot checked and graded for completion, but not checked for accuracy. I encourage you to get into a study group to help each other prepare for exams, quizzes, etc. Once these labs are graded and returned, I encourage you to compare answers with another class member, in your study group, who has also had the lab graded and returned.
I/We realize that the penalty for turning in work that is not my own, or assisting others in doing so, can range from an "F" in the class to dismissal from Trinity University. I realize that it is a violation of academic integrity to share any portion of this lab with any person (outside my 3343 team & professor)!

22-28] Write the complete code for PHP function, called Quadratic, which could be inserted in the code below
<H2> Quadratic2 - Author : Dr. Tom Hicks </H2>
<?PHP
-?- FUNCTION Quadratic
$R2 = 0;
Quadratic (2, 4, -6, $R1, $R2);
print ("A = 2 <BR>");
print ("B = 4 <BR>");
print ("C = -6 <P>");
print ("R1 = " . $R1 . "<BR>");
print ("R2 = " . $R2 . "<BR>");
?>
to render:
29] ______{T/F} Suppose that, after rendering the code above, we were to display the source code through the web server; we would be able to see the code in function Quadratic.
30] ______Write the output from the following code.
$Type = gettype(15.75);
print ($Type);
31] ______Write the output from the following code.
$Type = gettype(true);

$X = 5;
$X += 3;

34-38] Write the complete code for function FirstPrime which could be inserted in the block of PHP code below. This function is to explicitly return a string à the string will contain "0" if there is no prime. This function will return "INVALID - No must be greater than 0" if the number is greater than 20. This function will return "INVALID - No must be less than 50" if the number is greater than 20. Otherwise, this function is to explicitly return a string containing the lowest prime number of $No Less Than Or Equal To No. You must solve this with if-then-else.
<H2> FirstPrime - Author : Dr. Tom Hicks </H2>
<?PHP
-?- FUNCTION FirstPrime
print "First Prime <= 15 = " . FirstPrime(15) . "<BR>";
print "First Prime <= 11 = " . FirstPrime(11) . "<BR>";
print "First Prime <= 25 = " . FirstPrime(25) . "<BR>";
print "First Prime <= -1 = " . FirstPrime(-1) . "<BR>";
?>
