How to create html list from such array ?

[lp]

I've got an example array like this:

$myArr = array(
array("jj", "0", "jjj"),
array("ee", "0", "eee"),
array("bb", "ee", "bbb"),
array("ll", "ee", "lll"),
array("ff", "0", "fff"),
)

Where each row is an array with columns: id of list element, id of parent
list element ("0" means main node) and content of the element. So, from my
array I'd like to create a list like this:

<ul>
<li>jjj</li>
<li>eee
<ul>
<li>bbb</li>
<li>eee</li>
</ul>
</li>
<li>fff</li>
<ul>

Could anybody help me ?

Best regards.

Look's like a usual tree. Try to use not array, but SQL DB, it's easy

Sorry, but I can't use SQL here, the data deas not come from database. I've
got only array like that which will be passed to my class.

okay, it's worstly, but also real
you have to use 'usort' function that
looking for a $array[2] - (keys parent or not) and sorting an array.
It's only idea, not realization.

P.s sorry for my bad english

more little question: is you array sorted correctly?
if your array has
$myArr = array(
array("jj", "0", "jjj"),
array("bb", "ee", "bbb"),
array("aa", "0", "fff"),
)

then HTML should be

<ul>
<li>jjj</li>
<ul>
<li>bbb</li>
</ul>
</li>
<li>fff</li>
<ul>

or it have to be

<ul>
<li>fff</li>
<li>jjj</li>
<ul>
<li>bbb</li>
</ul>
<ul>

(sorted by name of parent keys)

This array ^ is wrong. There can't be any row with idParent = 'ee' if
there's no row with id = 'ee'.

I mean
$myArr = array([color=blue]

How about

$html = "<ul>\n";
$prv = -1;

foreach ( $myArr as $a )
{
$cur = $a[1];
$dat = "\t<li>{$a[2]}";

if ( $prv !== -1 )
if ( strcmp( $cur, '0' ) == 0 )
{
$dat = "</li>\n$dat";
if ( strcmp( $prv, '0' ) != 0 )
$dat = "\t\t</ul>\n\t$dat";
}
else
{
$dat = "\t\t$dat</li>\n";
if ( strcmp( $prv, '0' ) == 0 )
$dat = "\n\t\t<ul>\n$d at";
}

$html .= $dat;
$prv = $cur;
}

if ( strcmp( $prv, '0' ) != 0 )
$html .= "\t\t</ul>\n\t";
$html .= "</li>\n</ul>\n";
