Skoleopgave i PHP(2d array)?

Hej derude!

Jeg har faaet en opgave ind af doeren, som jeg ikke lige kan gennemskue.
Opgaven lyder saadan(engelsk):

Kode

Write a php program to simulate a table of 30 marks for a number of modules on a course using a
2-dimensional sequential array. The columns will be Mark Number, ModuleCode, Module Name and
Mark . Your 4 modulecodes and module names are COM147 Database; COM140 Hardware; COM137
Maths & COM177 Programming. The program will then print a table with all 30 rows generating
different modules, marks and summary values every time it is run.

The php program should:

Firstly allocate the values directly into the array ( $marks[ ][ ] ) within a for loop [array( ) - the array
function - should not be used]
- Mark Number should be assigned a number from 1 to 30
- Module Code should randomly assign one of the 4 module codes (use rand( ) function - see coin flip)
- Module Name should allocate the name of the randomly allocated module code (shown above)
- Mark should assign a randomly allocated mark between 0 & 100 (use rand( ) function)

Secondly use another for loop (preferable nested for loops) to print the 2-D array of values into an html
table including a header row plus print

- The overall average mark to 1 decimal place
- The number of times each module is chosen
- The average mark for each module to 1 decimal place
- The % pass rate for each module to 1 decimal place:
i.e. (number of marks of 40 and over/total number of marks) * 100

N.B. $marks[0][0] is row1 and column 1; $marks[0][1] is row 1 column 2 etc
$marks[1][0] is row 2 column 1; $marks[1][1] is row 1 column 2 etc

When assigning values into the array you should put the for loop variable as the row number so that
each time round the loop your are moving to a different row.

the php function round(number, decimal places) allows a number to be given to a set number of
decimal places so round(9.461, 1) gives 9.5

Jeg kan ikke lige gennemskue hvordan jeg skal goere?
Min forvirring kommer af jeg skal bruge bracket 2d array og tildele i en for loekke.

Er der nogle som kan pege mig i den rigtige retning?

Mvh Alex
