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 ) )

}
unset( $row );

foreach ( $arr as $k => $v )

else{

}
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)){?><tr><td ><a href="?ac=edit&type_id=<?php echo $arr['type_id'];?>">编辑</a> <a href="?ac=del&type_id=<?php echo $arr['type_id'];?>">删除</a></td></tr>
输出时怎么加?
你上面不是已经加了么?
那个是错误的啊,程序中用的是foreach循环,而不是while啊,while我也会
foreach($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

//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

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
