I want to use a multidimensional array and I get a really strange error as soon as I go into the third dimension.

PHP Code:

$pictures = explode('?#$'."\n", $help); //$help contains the gallery.inc

if (count($pictures) > 1) //two entries in the array indicate propper data
{
         $pictures[count($pictures) - 2] = explode('%#$'."\n", $pictures[count($pictures) - 2]); //split last sections pictures
         echo '<br>'.count($pictures[count($pictures) - 2]).'<br>';
         
         for ($i = 0; $i < count($pictures[count($pictures) - 2]); $i++)
         {
             $pictures[count($pictures) - 2][$i] = explode('&#$', $pictures[count($pictures) - 2][$i]); //sections > pictures > a picture
         }
} 


The error occurs as soon as I get into the loop. I can count the array in every dimension, but can't modify it, nor am I able to echo $pictures[count($pictures) - 2][$i] O_o

To clear things up, let's just assume the input is correct and we would get something like this:

0th explode:
pictures[] //empty

1st explode:
pictures[i] //entries, the 2nd is of interest

2nd explode:
pictures[2][i] //2nd consists of numberous entries (here 3)

3rd explode:
pictures[2][i][j] //split each of their entries into half

If I echo it I get an endless loop or growing data in one of the entries. I really have no clue why this won't work and really need some help

PHP Code:

        $help = 'fileA&#$contentA%#$
fileB&#$contentB%#$
?#$
fileC&#$contentC%#$
fileD&#$contentD%#$
?#$
';
        echo '<h1> help </h1>'.$help.'<br> x <br>';
        $pictures = explode('?#$'."\n", $help); //$help contains the gallery.inc
echo '<h1>pictures[i]</h1>';
foreach ($pictures as $i)
{
   echo '>> '.$i.'<br>';
}
        if (count($pictures) > 1) //two entries in the array indicate propper data
        {
         $pictures[count($pictures) - 2] = explode('%#$'."\n", $pictures[count($pictures) - 2]); //split last sections pictures
         
         echo '<h1>pictures[count($pictures) - 2]</h1>';
for ($i = 0; $i < count($pictures[count($pictures) - 2]); $i++)
{
   echo '>> '.$pictures[count($pictures) - 2][$i].'<br>';
}
         for ($i = 0; $i < count($pictures[count($pictures) - 2]); $i++)
         {
          $pictures[count($pictures) - 2][$i] = explode('&#$', $pictures[count($pictures) - 2][$i]); //sections > pictures > a picture
     }
} 


The output is:

help

fileA&#$contentA%#$ fileB&#$contentB%#$ ?#$ fileC&#$contentC%#$ fileD&#$contentD%#$ ?#$
x

pictures[i]

>> fileA&#$contentA%#$ fileB&#$contentB%#$
>> fileC&#$contentC%#$ fileD&#$contentD%#$
>>

pictures[count($pictures) - 2]

>> fileC&#$contentC
>> fileD&#$contentD
>>

and it repeats itself after this. Any idea why? I've had it with that stupid array, it is supposed to work but it doesn't at all O_o

Er, I don't think we quite understand what you are trying to do or how it is supposed to work? This is for some kind of image gallery right?

Yes it is. It's fairly simple and will result into a three dimensional array, though not all of the elements will be asigned. The first explode will build the entries on the x-axis. The second explode will create entires on the y-axis at x=1. So far that's nothing special and we'll get a line f(x = 1,y) = x+y. Note that x=0 and x=2 won't have any values, and the explode will only effect the information in x=1 anyway (look at the string parameter).

Okay, fiarly simple. Now let's go into the third dimension by splitting each of the y elements into two values z=0 and z=1. To get all of the y rows splitted we'll just loop trugh them. Now this is where the error occurs.

If you couldn't follow the explanations so far, this visual should clear you up:

0st explode: nothing O_o

1st explode: only x-axis, echoed above as pictrues[i]

a b c

2nd explode: x-axis and y-axis, though only on x=1. Echoed above as pictures[count($pictures) - 2]

0 f 0
0 e 0
a d c

3rd explode: z-axis in x=1 and y=t 0<=t<=2 //that beeing the loop

z=0
0 g 0
0 i 0
a k c

z=1
0 h 0
0 j 0
a l c

so we go from (x,y,z)= (1,0,0) to (1,0,1) to (1,1,0) to (1,1,1) to (1,2,0) to (1,2,1). As mentioned above, the errors is the third dimension and I realy don't know why.

What part in your gallery does it play?

In your second post above where you have some test output, what should it display instead?

The outputs of the first two steps are prefectly okay. The problem is the third explode. Although nothing changed, I am not able to propperly execute the loop. The whole script runs endlessly and the first explode is somehow overwritten. The echo above showed you the steps before the loop. With the loop I get (inifinite times):

//Edit:

Okay ... I'm dumb O_o
The array itself is fine and it works perfectly. The problem with the loop was, that it was in another loop with the same counter. Now that I changed it from i to j it works as expected
