How do you find the size of an array in PHP?
To find the size of an array in PHP you can either use the count() function or the sizeof() function as they will produce the same result. <?php $array = array(1, 2, 3, 4, 5, 6, 7); echo count($array); // outputs 7 echo sizeof($array); // outputs 7 ?>
How do you draw an array to find the product of 4 multiplied by 5?

How do you count how many results are in a PHP array?
To find out how many results there are in a PHP array all you need to do is use the function count() like I have shown you in the example below.
How do you pick a random value from a PHP array?
To pick random results from an array in PHP you will need to use the array_rand() function, you can select the amount of results you wish it too select too. <?php $array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); $rand_results = array_rand($array, 3); // will select 3 random results from the array and store in a new array ?>
What two methods can be used to find the soution of the equation x plus 4 equals 13?
1) x+9=13 (subtract 9) x=4 2) x+9=13 (divide by 9) x/9+1=13/9 (use Pascals theorem of 1) (x+4)/2=4 x+4=8 x=4
How can you use an array to find the product of 4 x 13?
You can do 4 rows and 13 columns and you get 52. product = sizeof (char [4][13]); of course it is just a joke, in actual code you write product = 4*13;

How can you mix up the order of values in a PHP array?
To shuffle an array in PHP is easy to do, all you need to use is the shuffle() function like shown below: <?php $array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); shuffle($array); // array results will be randomly shuffled ?>
How do you initialise a two dimentional array?
C provides rectangular multidimensional arrays. In C, a two-dimensional array is really a one-dimensional array, each of whose elements is an array. An array is initialized by a list of initializations in braces; each row of a two-dimensional array is initialized by a corresponding sub-list. Example of two dimensional array initialization: char array_example[2][4] = { {11, 12, 13, 14}, {21, 22, 23, 24} };
What is meant by irregular dimensional array?
An irregular dimensional array is a special type of multi-dimensional array.First we must understand that a multi-dimensional array is just an array of arrays. Each element in the array is, itself, an array of elements.A regular multi-dimensional array will be an array of size n, with each element containing a separate array of size m. That is, each sub-array has the same size.An irregular multi-dimensional array will be a multi-dimensional array in which each sub-array does not contain the same number of elements.Regular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4, 5}array[2] = new array{6, 7, 8}array[3] = new array{9, 10, 11}This regular array is an array of size 4 in which each sub-array is of size 3.Irregular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4}array[2] = new array{5, 6, 7}array[3] = new array{8, 9, 10, 11}This irregular array is an array of size 4 in which the size of each sub-array is not the same.

How you use negative index in array?
You cannot do this easily in C programming. Arrays in C always start with index 0. If you must use a negative array index, you can do that by allocating an array, and then pointing to an element within the array. Say you allocate an array 10 ints long, named a; then set b = &a[5]. Then b[-4] = a[1]. However, this is extremely bad programming practice and is almost certain to cause data corruption. Some compilers will treat array indices as unsigned, also, so that when you specify b[-4], the compiler will internally simplify that to b[65532] and your program will crash.
