It's buggy... you need to test for an blank string to properly handle
the append to array case when the index is blank [].
?php
$node = '[5][1][]';
$text = 'some text';
preg_match_all(
'|\[([^\]\[]*)\]|', $node, $matches, PREG_PATTERN_ORDER );
$recursive = $matches[1];
$recursive = array_reverse($recursive);
foreach( $recursive AS $index )
{
$out = array();
if( trim( $index ) === '' )
{
$out[] = $text;
}
else
{
$out[$index] = $text;
}
$text = $out;
}
print_r( $out );
?
I also removed the (int) cast since integer keys will be cast
automatically by PHP and then it will have support for text keys also.
Cheers,
Rob.

I probably shouldn't trim... since we're not supporting quotes in any
way, it might be desirable to have a key that is one or more spaces...
for whatever reason :)
Personally, I have a similar implementation I use all the time, but I
use forward slashes to separate keys.

I really don't like to use the EVAL function, but do I have choice??
This sucks.
Hi there,
While this question can spur some neat solutions, it raises a red flag
in that if you need to do this, you probably need to rethink things a
bit.
In cases like this it is easier for people to help if you describe the
actual problem you are trying to solve, not how you think it needs to
be solved. It could be that you don't really need weird (but
beautiful, like Jim's idea) solutions. If you explain why you believe
that you need to do this in the first place, maybe someone can suggest
something else which doesn't require a weird solution (however
beautiful).

Hi, I am aware of this, but explaining my problem in this case would
take me an hour --- and eventually would lead to a) misunderstanding, b)
weird solution, c) no solution...

You should print the results that you are looking for!
Are you looking for something like this?
Array
(
[5] = Array
(
[1] = Array
(
[0] = some text
)
)
)
how is the $node string being created?

Re: [PHP] Dynamically creating multi-array field
No offense, but I thought it's obvious what I want to print.
print_r() shows null, and it should print what you just wrote = array field.
It works when first defining with eval():
eval('$tpl'.$node.'=array();');
I guess that's the only way.
Anyway, I appreciate your quick reply,
Martin

Nope, you have to use the eval() everytime for read/write.
