MYSQL テーブル スキーマ:

$res = mysql_query("SELECT `id`, `name`, `url` FROM `categories` WHERE `type`='category' ORDER BY `name` ASC") or die(mysql_error());
while ($arr = mysql_fetch_array($res))

私はこのコードを試します、その作品..あなたはこれを試します...

CREATE TABLE IF NOT EXISTS `categorylist` (
 `id` int(5) NOT NULL auto_increment,
`cname` varchar(25) collate utf8_unicode_ci default NULL,
`pid` int(5) NOT NULL,
PRIMARY KEY  (`id`),
KEY `pid` (`pid`)
) ;



INSERT INTO `categorylist` (`id`, `cname`, `pid`) VALUES
(1, 'Entertainment', 0),
(2, 'movies', 1),
(3, 'actor', 2),
(4, 'actress', 2),
(5, 'Drama', 1),
(7, 'sports', 0),
(8, 'comedian', 2),
(9, 'political', 0);



<?php
include "header.php";
 include "dbconn.php";

 $qry="SELECT * FROM categorylist";
 $result=mysql_query($qry);


 $arrayCategories = array();

 while($row = mysql_fetch_assoc($result)){ 
    $arrayCategories[$row['id']] = array("pid" => $row['pid'], "name" =>  $row['cname']);   
  }
//createTree($arrayCategories, 0);

 function createTree($array, $currentParent, $currLevel = 0, $prevLevel = -1) {

foreach ($array as $categoryId => $category) {

    if ($currentParent == $category['pid']) {                       

        if ($currLevel > $prevLevel) echo " <ul> "; 

        if ($currLevel == $prevLevel) echo " </li> ";

        echo '<li id="'.$categoryId.'" onclick=child(this.id);><span>'.$category['name'].'</span>';

        if ($currLevel > $prevLevel) { $prevLevel = $currLevel; }

        $currLevel++; 

        createTree ($array, $categoryId, $currLevel, $prevLevel);

        $currLevel--;               
    }   

}

if ($currLevel == $prevLevel) echo " </li>  </ul> ";

}   
?>
<div id="content" class="general-style1">
<?php
 if(mysql_num_rows($result)!=0)
 {
?>
<ul>
    <li id="0" class="root"><span>Categories</span>
    <?php createTree($arrayCategories, 0); ?>
</li>
</ul>
<?php
}

あなたのデータは間違っています：

(9, 5, 'Meat', 'meat', 'category'),

する必要があります：

(9, 9, 'Meat', 'meat', 'category'),

と

(10, 5, 'Salami', 'salami', 'subcategory'),
(11, 5, 'Sausages', 'sausages', 'subcategory'),
(12, 5, 'Ham', 'ham', 'subcategory'),
(13, 5, 'Delicatessen', 'delicatessen', 'subcategory'),
(14, 5, 'Frankfurters', 'frankfurters', 'subcategory'),
(15, 5, 'Polony', 'polony', 'subcategory'),
(16, 5, 'Smoked', 'smoked', 'subcategory'),
(17, 5, 'Pate', 'pate', 'subcategory');

する必要があります：

(10, 9, 'Salami', 'salami', 'subcategory'),
(11, 9, 'Sausages', 'sausages', 'subcategory'),
(12, 9, 'Ham', 'ham', 'subcategory'),
(13, 9, 'Delicatessen', 'delicatessen', 'subcategory'),
(14, 9, 'Frankfurters', 'frankfurters', 'subcategory'),
(15, 9, 'Polony', 'polony', 'subcategory'),
(16, 9, 'Smoked', 'smoked', 'subcategory'),
(17, 9, 'Pate', 'pate', 'subcategory');
