PHP HTML 无限分类

$link = mysql_connect( '127.0.0.1', 'root', '520928' ) or die( mysql_error() );//连接数据库服务器
mysql_select_db( 'test' );//选择数据库
mysql_set_charset( 'utf8' );//设置字符编码

$sql = "SELECT * FROM wxtree";//查询分类表
$result = mysql_query( $sql );
$tree = array();//初始化一个数组
while( $row = mysql_fetch_assoc( $result ) )
{
$tree[$row['fid']][$row['id']] = $row['cat_name'];//创建分类数组
}
unset( $row );

mysql_close( $link );//关闭数据库


echo '-------------------------------------------' . "\n";

//递归函数

function for_category( $arr = array(), $arr2 )
{

echo "
    ";
    foreach ( $arr as $k => $v )
    {
    if ( isset( $arr2[$k] ) && is_array( $arr2[$k] ) )
    {
    echo "
  • $k $v" ;
    for_category( $arr2[$k], $arr2 );
    echo "
  • ";
    }
    else{
    echo "
  • $k $v
  • ";
    }
    }
    echo "
";

}
for_category( $tree[0], $tree );

?>

这种改如何添加各种操作啊,while循环中的话可以添加,foreach如何添加

回复讨论(解决方案)

输出条目时上去不就行了?

怎么做啊,我刚学,while

while($arr = mysql_fetch_array($res)){?>编辑 删除
Copy after login

输出时怎么加?

你上面不是已经加了么?

那个是错误的啊,程序中用的是foreach循环,而不是while啊,while我也会

foreach($arr as $value){
echo "";
echo "
";
}
?>

foreach($arr as $value){
echo "
";
echo "
";
}
?>
上面那个打错了。
如果你assoc 出来是只有ID就直接加$value 否则,你应该知道如何做

"; foreach ( $arr as $k => $v ) { if ( isset( $arr2[$k] ) && is_array( $arr2[$k] ) ) { echo "
  • $k $v        编辑    删除"; for_category( $arr2[$k], $arr2 ); echo "
  • "; } else{ echo "
  • $k $v     热门群组ddd    编辑    删除
  • " ; } } echo ""; } for_category( $tree[0], $tree );?> "; foreach ( $arr as $k => $v ) { if ( isset( $arr2[$k] ) && is_array( $arr2[$k] ) ) { echo "
  • $k $v        编辑    删除"; for_category( $arr2[$k], $arr2 ); echo "
  • "; } else{ echo "
  • $k $v     热门群组ddd    编辑    删除
  • " ; } } echo ""; } for_category( $tree[0], $tree );?>
    Copy after login

    //真正的效果是这样的,做一个无限级分类,采用递归调用的方法,这里的

  • 之间无法加入链接啊

    echo "

  • $k $v热门群组ddd 编辑 删除
  • " ;
    双引号中的双引号要转义!
    echo "
  • $k $v热门群组ddd 编辑 删除
  • " ;
