Although in fact this does work on both PHP 4.4.4 and PHP 5.2.0. Way
to go with the alarmist documentation which means I still don't know
whether it's right or just happens to work.
In fact if there's one thing I hate more than PHP itself right now
it's the fact that its online documentation is rammed to the gills
with cargo-culted half truths, suspicions and downright rubbish.
<?php
$list = array(
'1' => array(
'name' => 'Frib',
'parent_id' => '3'
),
'2' => array(
'name' => 'Frob',
'parent_id' => '3'
),
'3' => array(
'name' => 'Top 1',
'parent_id' => null
),
'4' => array(
'name' => 'Top 2',
'parent_id' => null
),
'5' => array(
'name' => 'Frub',
'parent_id' => '4'
),
'6' => array(
'name' => 'Freb',
'parent_id' => '4'
)
);
$root = array();
foreach ($list as $id => $obj) {

$root[] =& $list[$id];
} else {
$list[$obj['parent_id']]['children'][] =& $list[$id];
}
}
print_r($root);
?>
