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.
