i need to sort the 10 numbers that i'll input the textbox but i don't know how.. and i need to declare the highest and lowest number.. example..
i'll input
2 56 3 76 35 54 4 7 31 0..
the output will be
0, 2, 3, 4, 7, 31, 35, 54, 56, 76
therefore.. 0 is lower than 2 and 3 is higher than 2...
tnx again!!!! godbless you all!!!!

I hope this isn't homework however
[php]
$arr = explode(' ',$_POST['num']); //assumes space delimted
arsort($arr);
print_r($arr);
[/php]
sort() will do the job but arsort() is for reverse order. -
<?php
-
echo "<u>Output:</u></br></br>";
-
$arr = explode(' ',$_POST['num']); //assumes space delimted
-
sort($arr);
-
-
echo implode(',',$arr );
-
-
?>

how can i put the lowest number in left side one by one?
example.. i'll put the 5 numbers in input box..
5 23 4 6 8
number 4 is lower than 23 so it will move at left sides of number 23 and number 5.. it will be come..
4 5 23 6 8
then the next is 5.. the question will ask.. 5 is higher than 4 and lower than 23..
then the next is 6.. 6 is lower than 23 so it will move at 23's left's side..
4 5 6 23 8
then the next is 8.. 8 is lower than 23, so it will move at left side..
4 5 6 8 23..
then it says.. 4 is lowest number and 23 is the highest number..
plz help me.. this is my first time to used php that's why i'm 0 knowledge bout this..
thankx!!!!c",
How about this?
[php]
<?php
$numbers = "5 23 4 6 8";
$number_array = explode(" ",$numbers);
asort($number_array);
echo "Numbers sorted: ".implode(" ",$number_array);
?>
[/php]
but.. i have a textbox and i need to input the 5 numbers in textbox.. not in program.. so it depend on me what numbers i will input.. i used $_POST["num"] as a name of textbox.. thank you!
[php]
<?php
$number_array = explode(" ",$_POST['num']);
asort($number_array);
echo "Numbers sorted: ".implode(" ",$number_array);
?>
[/php]
Bubble sort works like this:
Find the size of your array: $size.
Analyze your array, starting at index 0, moving to index $size - 1, and find the position of your largest element: $maxPos.
Swap the values of position $size and position $maxPos.
Decrement $size: $size--.
Repeat until $size == 0.

thank you.. it's worked but i need it manually.. the code you gave to me is automatically sorted.. how can i separate the 5 numbers i will input in textbox?..
example.. i'll input in textbox..
5 2 3 54 4
the output will be..
-----------------------
5 2 3 54 4
2 is lower than 5
-----------------------
and the number of 2 will move at the left side of 5..
the output will be...
------------------------
2 5 3 54 4
2 is lower than 5, ang 5 is higher than 2
thank you again..

Please read through my second post in this thread, I delineate the algorithm there for you.

Heya, Ehcy.
The experts on this site are more than happy to help you with your problems but they cannot do your assignment/program for you. You have not asked a question. Attempt the assignment/program yourself first and post questions regarding any difficulties you have or about a particular function of the code that you don't know how to achieve.
Please read the Posting Guidelines and particularly the Coursework Posting Guidlines.
Then when you are ready post a new question in this thread.

Sit down and do some reading on PHP. You will need to know PHP before we can help you write PHP code.
Then work through the problem step by step: a good start would be to post the code you wrote to accomplish the first line of my instructions.
