Okay, total newbie when it comes to arrays, and I could really use some
help. I sure this will be an easy one for you veterans out there.
Here is the array ($code):
array(2) {
[total]=
int(1)
[assign]=
array(1) {
[1]=
array(3) {
[type]=
string(10) Transcript
[rows]=
string(3) 603
[codeapply]=
array(1) {
[1]=
array(3) {
[codeset]=
string(23) FFT 6 Level Code System
[code_rows]=
string(3) 302
[code_complete]=
string(1) 2
}
}
}
}
}
Here is the output code:
foreach ($this-code['assign'] as $assign = $details)
{
foreach ($assign['codeapply'] as $codeapply = $ca_details)
{
echo tr;
echotd;
echo$details['type']. .$assign;
echo/a;
echo/td;
echotd;
echo$ca_details['codeset'];
echo/td;
echotd;
echo
$ca_details['code_complete']./.$ca_details['code_rows']. Items Coded;
echo/td;
echotd;
printf ( %.0d%%,
($ca_details['code_complete']/$ca_details['code_rows'])*100);
echo/td;
echo /tr;
}
}
Output error:
Warning: Cannot use a scalar value as an array
Warning: Invalid argument supplied for foreach()
Conceptually and practically I have been struggling with how to navigate
levels of the arrays which are defined by a variable (e.g.
$code['assign'][$i] for the assign ID and $code['assign'][$i][$j] for the

You have two mutually exclusive possibilities there.
Probably, what you want to do is something like:
$code['assign'][$i]['aid'] = (assign ID);
$code['assign'][$i][$j] = (whatever you want here);
(which, for simplicity, translates into something like:)
$code['assign'][1]['aid'] = 1;
$code['assign'][1]['1'] = 11;
$code['assign'][1]['2'] = 12;
$code['assign'][1]['3'] = 13;
$code['assign'][1]['4'] = 14;
$code['assign'][1]['5'] = 15;
etc.

[PHP] Re: Foreach Array Help
First of all, thanks for the response.
Here is where I am getting lost:
In $code['assign'][1] - 1 is the assignment ID, and I would like the array
to be able to hold a billion of these different assignments all with
conceivably a billion codeapply ID as in $code['assign'][1]['codeapply'][3],
where 3 is the codeapply value. In other words, because each of these
items directly under assign and codeapply are arrays because they hold
sub-info, I have made the keys of these items the values.
So - am I approaching this whole array thing wrong?
Thanks.

[PHP] Re: Foreach Array Help
Never mind - I figured it out.
While I was traversing like this:
foreach ($this-code['assign'] as $assign = $details)
{
foreach ($assign['codeapply'] as $codeapply = $ca_details)
{
}
}
I had set up $assign to be the key value, and likewise not be an array. I
changed it to:
foreach ($this-code['assign'] as $assign = $details)
{
foreach ($details['codeapply'] as $codeapply = $ca_details)
{
}
}
and it worked beautifully. Thanks to all of you who got me going in the
right direction.

I still don't understand exactly what you want to do, but see below...

help. I sure this will be an easy one for you veterans out there.

array(2) {

array(1) {
[1]=
array(3) {

}
}
Here is the output code:
foreach ($this-code['assign'] as $assign = $details)
{
Here, $assign is a key from the $this-code['assign'] array. Since,
according to the array above, assign has only one element, and the key to
that element is '1', $assign will always be one and this code run through
just once. $details is an array with three key/value pairs. They are
'type' = 'Transcript', 'rows' = '603', and 'codeapply' = (an array).
foreach ($assign['codeapply'] as $codeapply =
$ca_details)
{
So, looking at this it looks like what you actually want to do is:
foreach($details['codeapply'] ... )
$details['codeapply'] has a single key/value pair, which is ('1' = (an
array)). This array can be reached by using $ca_details['codeset']... etc.
echo tr;
echotd;
echo$details['type']. .$assign;
echo/a;
echo/td;
echotd;
echo$ca_details['codeset'];
echo/td;
echotd;
echo
$ca_details['code_complete']./.$ca_details['code_rows']. Items
Coded;
echo/td;
echotd;
printf ( %.0d%%,

echo/td;
echo /tr;
}
}
