PHP嵌入html代码

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

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 &nbsp&nbsp&nbsp &nbsp&nbsp&nbsp编辑&nbsp&nbsp&nbsp 删除"; for_category( $arr2[$k], $arr2 ); echo "

"; } else{ echo "

$k $v &nbsp&nbsp&nbsp 热门群组ddd &nbsp&nbsp&nbsp编辑&nbsp&nbsp&nbsp 删除

" ; } } echo ""; } for_category( $tree[0], $tree );?> "; foreach ( $arr as $k => $v ) { if ( isset( $arr2[$k] ) && is_array( $arr2[$k] ) ) { echo "

$k $v &nbsp&nbsp&nbsp &nbsp&nbsp&nbsp编辑&nbsp&nbsp&nbsp 删除"; for_category( $arr2[$k], $arr2 ); echo "

"; } else{ echo "

$k $v &nbsp&nbsp&nbsp 热门群组ddd &nbsp&nbsp&nbsp编辑&nbsp&nbsp&nbsp 删除

" ; } } echo ""; } for_category( $tree[0], $tree );?>
//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 &nbsp&nbsp&nbsp 热门群组ddd &nbsp&nbsp&nbsp编辑&nbsp&nbsp&nbsp 删除

" ;
双引号中的双引号要转义！
echo "

$k $v &nbsp&nbsp&nbsp 热门群组ddd &nbsp&nbsp&nbsp编辑&nbsp&nbsp&nbsp 删除

" ;
