[RESOLVED] another array problem...

choubix

hello, i really have problems with arrays... sorry to keep asking you but really need to get this script up and running.

the user selects 6 numbers in a list
I have to store this list in $_SESSION['liste']; (I cant do it differently)

the list is stored like that: 34-21-44-32-12-11 (cant do it differently either)

what I need to do is to explode the array, get rid of the - , sort the values in ascending order and send them to my table as a string.

so in the end I should have: 111221323444

I tried using a variation of laserlight's script (given in a previous post) without success... 🙁

hope that someone will have time to give me a hand again in telling me what I could change in saberlights script to make it work.

really appreciate your support guys.

Why not? Though in this form it should be fine, unless you allow negative numbers.

what I need to do is to explode the array, get rid of the - , sort the values in ascending order and send them to my table as a string.

Use [man]explode/man, [man]sort/man and [man]implode/man.

By the way, the username is laserlight, not saberlight :p

<?php

$string = '34-21-44-32-12-11';

// we make an array of bits where the separator is '-' in the string
$arr1 = explode('-',$string);

// we sort the array from lowest to highest value
sort($arr1);

// we add together all values in array, into a string
// the glue in this case is not '-'
// but empty '', which means nothing
$newstring = implode('',$arr1);

echo $newstring;

halojoy, let choubix try it out first before giving a concrete example since choubix was not on the right track to begin with.

Remember laserlight
that a concrete example can be just as educational.
Of course even better if this concrete example includes some comments.
Which I will add now.

... after the user has made an attempt, otherwise there is the temptation to just copy without understanding.

hi laserlight, I was editing when you were posting i guess 🙂

just to let you know: when I post that means that i have tried what i thought would work. but given my limited knowledge of php I can try only 4 / 5 differents ways...

I hate just copying code...

i tried this:

$list = $_SESSION['liste'];
$exploded = explode ("-", $list);
$sort = sort(exploded)
print "$sort";

to me that means that i remove the - in $list then I sort it.
(the print is just to see whether I can store the array as a string)

but this doesnt work...
also tried with a loop but really dont think this is the right way.
also tried to play with laserlight's code: unsuccessful...

Ah, now would be a good time to look at halojoy's example. I believe that example to be correct, and it pretty much uses what I suggested in the order suggested, heheh.

I completly forgot the implode in what i was doing + there was a syntax problem in my explode.

see: knowledge is cumulative thanks to you guys ! 🙂
