This is one question that came out during PHP Programming Interview.

Displaying random number from 1-100 and is sorted as much as the number who entered. eg input 8 results:
Show eight times a random number from 1-100: 5, 84, 97, 19, 71, 31, 45, 90
Result sequence of random numbers from small to large: 5, 19, 31, 45, 71, 84, 90, 97

so,i’m gonna use bubble sort for sorting, but what is bubble sort? Bubble sort is a simple sorting algorithm. It works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted. The algorithm gets its name from the way smaller elements “bubble” to the top of the list. Because it only uses comparisons to operate on elements, it is a comparison sort.(Source:http://en.wikipedia.org/wiki/Bubble_sort)
Pseudocode implementation

procedure bubbleSort( A : list of sortable items ) defined as:
n := length( A )
do
swapped := false
for each i in 0 to n - 1 inclusive do:
if A[ i ] > A[ i + 1 ] then
swap( A[ i ], A[ i + 1 ] )
swapped := true
end if
end for
n := n - 1
while swapped end procedure

sample implementation in PHP:

if(isset($_POST['nilai']))
$a=$_POST['nilai'];
define(MAX_NUMBER,$a);
echo "Tampilkan bilangan acak $a kali dari 1 - 100 : \n";

for($x = 0; $x <= MAX_NUMBER-1; $x++)
$ran[$x] = rand(1, 100);
echo $ran[$x] ."\n";

for($x = 0; $x < MAX_NUMBER-2; $x++) {
for($y = 0; $y < MAX_NUMBER-2-$x; $y++) {
if($ran[$y] > $ran[$y+1]) {
$hold = $ran[$y];
$ran[$y] = $ran[$y+1];
$ran[$y+1] = $hold;
}
}
}
echo "Hasil urutan bilangan acak dari yang kecil ke yang besar :";
for($x = 0; $x < MAX_NUMBER-1; $x++)
print $ran[$x] ."," . "\n"; ?>


Hello i want to share my experience in PHP Programming Interview as much as10 times according from my experience and my friends, i’ll divide this interview for three kinds:
1.Demo Portfolio + interview
2.Test Logic Programming + interview
3.Test Web Programming + Psikotest + interview

Ok, now I’ll explain the first type. when you came to the company, he/she directly asked you:do you bring portfolio?, then obviously you will only make your portfolio presentation. here you must gives a good picture of your software, it will be better if you use PPT for your presentation. most of the companies will see your ability and ask you to do Debugging and Tracing program.
In the second type, at the beginning of your meeting will be asked to fill out forms about yourselves and then after that you will conducted interviews about your ability, then after that will be asked to do some test, Here will be a matter of logic programming that relies on your logic skills. many of the questions from this test most are eight questions, the usual question out on processing text, string, and others(Fibonnaci,Prime).
In the third type , you will be given a basic question about php, css, javascript, mysql you can certainly pass the test after that there was the next question here increased to an intermediate level, you will be asked to make some programs such as: Log in and Registration, Validation, etc.

So, it will be better for U to prepare for PHP Programming Interview with some exercise. Such as Logic Programming, Basic/Intermediate Web Programming, and Debugging and Tracing your program. Sorry if my english so bad ~_~”

Still progress!!
