I have a programmng assignment to give in next week, and I was wondering if someone could help me answer these questions :

Exercise 1

The following set of short questions will focus on getting you familiar with how to write PHP

functions as well as how to make use of the pre-existing PHP functions. All your PHP functions

must be declared in the document body section and each functions name must be as specified

below. To demonstrate the functionality of each method, you must make function calls in the

document body. Include a heading (h1 h6) that indicates which function is being tested before

each function demonstration. The use of Global Variables is forbidden! Test all your functions

with some relevant input parameter values.

A. Function: computefactorial

Parameter(s): Number

Given the number, find its factorial and return it. If the parameter is not an integer

number or if it is a negative number, return false.

B. Function: findMostFrequent

Parameter(s): String Array

Outputs the string (element) that appears the most frequently within the array with its

frequency of repetition. Strings should be case insensitive.

C. Function: toUppercaseFirst

Parameter(s): String

For each word in the string, capitalize (uppercase) the first letter, and make sure the rest

of the letters of all words are lower case, then return the modified string.

D. Function: splitCapitalizeSort

Parameter(s): String

Given the string, place each word into an index array and then capitalize (uppercase) the

first letter of all those words in the array, then sort the array alphabetically. The return the

resulting array. Duplicated words, if any, are kept.

E. Function: dayofNextFriday

Parameter(s): None

Return the date of the next Friday in the following format: DD/MM/YYYY.

(if today is Friday return the date of next Friday)

F. Function: findUniqueandSort

Parameter(s): Array of integer numbers

Scan the entire array and print out the array excluding any duplicate elements, then sort

the array. Example: input Array a = 1,3,2,1,3, 1 would output 1,2,3.

G. Function: sortHash1

Parameter(s): Associative Array

Given an associative array using full-names as keys and annual salaries as values; in a

table format, print out the name and corresponding salary of each individual in increasing

order (from lowest salary to the highest).

H. Function: sortHash2

Parameter(s): Associative Array, code

Write a PHP function to accept an associative array (as follows) and a code as input

parameters, and then sort the input associative array as follows. Example of the input array:

array("Jack"=>"55",

"Anita"=>"30","Ramesh"=>"40","Sophia"=>"21","Nastran"=>"41","William"=>"39","Davi

d"=>"5") in :

a) if code =1: ascending order sort by value

b) if code =2: ascending order sort by Key

c) if code =3: descending order sorting by Value

d) if code =4: descending order sorting by Key

e) For other values of code: Function only prints (Wrong Code)

I. Function: averageTemp

Parameter(s): Associative Array

Write a PHP function to calculate and display average temperature, and four lowest and

highest temperatures.

Recorded temperatures are : [78, 60, 62, 68, 71, -17, 52, 68, 73, 85, 66, 64, 76, 63, 75, 76,

73, 68, 62, 73, -10, 72, 65, 80,74, 62, 62, 65, 64, 0, 68, 73, 75, 79, 73, 77]

Expected Outputs:

Average Temperature is : Average Value

List of four lowest temperatures : -17, -10, 0, 52

List of four highest temperatures : 79, 80, 81, 85

J. Function: findatStartorEnd

Parameter(s): word, string

Write a PHP function to test if a given word occurs at the beginning or at the end of a

given string. If yes, it returns: True, otherwise it returns: False

Example for: I love PHP, PHP --? function returns : True

Example for: I love PHP and C++, PHP --? function returns : False

Thank you!
