[PHP] Re: Simple array question, array delete
Anyway, as the replies already show, you have to have a key to identify the record to be deleted, otherwise, I don't see there can be a way. Why don't use the data as key as well?

[PHP] Re: Simple Array question (conclusion)
I GOT IT
this is where the data was coming from:
input name=id[sh123] type=hidden id=id[sh123] value=32
input name=id[sh1sd] type=hidden id=id[sh1sd] value=563
and this is where i take the values and dump it into an array/variables that
i can call when and where i please:
?php
$nn=0;
foreach($id as $nname = $pppno)
{$asdf[$nn]=$pppno;
$nn++; }
?
brbr?php echo $asdf[0]; ?br
?php echo $asdf[1]; ?
I just took out some of the breaks so it will take less space but you get
the idea.
Thank you to everyone who tried to help, but maybe i didnt explain the
problem well enough that you didnt get the answer or just didnt want to :-D

How do i get the value of id[]?
eg:
I dont want the sh1 and sh2, i just want the 3 and 4
The reason i dont wan the sh1 and sh2 is those are dynamic and will be
changing, I just need the values (in this case 3 and 4) to do some

Echo of one is and echo of two is:

AS you can see its totally wrong.Any other ideas?
No... you're getting exactly what you ask for. You rely on this list to
much.
1. You have no braces so your foreach() is taking the next line as the
part that should be executed on each loop.
2. Loop 1 sets $row = 32. Then it's displayed
3. Loop 2 sets $row = 563. Then it's displayed
4. So now $row = 563. When you display $row[0], you're asking for the
first character of $row, so 5 is displayed. $row[1] displays 6.
5. Now you go back to $id. Well, $id = array('sh123' = 32, 'sh1sd' =
563). So, when you try to display $id[0] and $id[1], there are no
cooresponding values, so nothing is displayed.
Now, how do you do this correctly?
foreach($_POST['id'] as $key = $value)
{ echo The random key is $key, the value is $value.br /; }
which will give you:
The random key is sh123, the value is 32.
The random key is sh1sd, the value is 563.
What do you want, besides that?

Seriously?
You could just replace the above with:
$asdf = array_values($_POST['id']);
I think you need to be cut off from the list for a while. Trial by fire,
I say!!

Hey John,
I guess you are right, I do rely on this list quite a bit but am not the
only one.
Am learning by my mistakes though and finding solutions...they may not be
the best solutions but they still work, everyone has to learn.
Thanks for replying to the question though. And i didnt know about the
array_values thingsee? the more you reply to me the more i learn :-D
Cheers,
-Ryan
