I don't seem to understand arrays

[Anon]

Hi all,

Please help me.

I'm trying to create a multidimensional array that gets incrementally added to as my program cycles through a for loop.

With a standard array I know you can write the code:

for($i=0; $i < $numunits; $i++)
{
$array[] = $numunits * $i;
}

And that incrementally adds data to the array.

However, I've tried to do this to create a multidimensional array using the following code:

for($i=0; $i < $numunits; $i++)
{
$array[] = array($var1 => array($var2, $var2));
}

When I cycle through this resultant array, none of my data is there, but I have index numbers from 0 - 26 (which is sort of right, as there are 27 things I want in there).

I tried taking off the first use of array, like:

for($i=0; $i < $numunits; $i++)
{
$array[] = ($var1 => array($var2, $var2));
}

and that gives me a syntax error.

I tried taking off the square brackets, like:

for($i=0; $i < $numunits; $i++)
{
$array = array($var1 => array($var2, $var2));
}

But that only gives me the 27th piece of data.

Is what I am doing just insane or is there a way to do it?

Cheers,

Owen

Hi,

you might want to try

for($i=0; $i < $numunits; $i++)
{
$array[$var1] = array($var2, $var2);
}

not tested though...

Well, I've sort of gotten somewhere with the code:

for($i=0; $i < $numunits; $i++)
{
temparray = ($var1, $var2, $var2);
$array[] = temparray;
}

Which isn't quite what I had in mind, but seems to provide all the data I originally wanted to get at.

I'm now going to try Dominique's suggestion and see if that provides what I originally wanted.

Hi Dominique,

You're a star. It works perfectly.

Thanks
