下面是一个通过PHP递归函数实现权限树检查的示例代码:
<?php
// 定义权限树结构
$permissions = array(
'user' => array(
'create' => true,
'read' => true,
'update' => true,
'delete' => true
),
'post' => array(
'create' => true,
'read' => true,
'update' => false,
'delete' => false
),
'comment' => array(
'create' => true,
'read' => true,
'update' => false,
'delete' => false
)
);
// 定义用户权限
$userPermissions = array(
'user' => array(
'create' => true,
'read' => true,
'update' => true,
'delete' => false
),
'post' => array(
'create' => true,
'read' => true,
'update' => false,
'delete' => false
)
);
// 递归检查权限
function checkPermission($permissions, $userPermissions)
{
foreach ($permissions as $key => $value) {
if (is_array($value)) {
checkPermission($value, $userPermissions[$key]);
} else {
if ($value !== $userPermissions[$key]) {
echo "权限不足:$key/$value\n";
}
}
}
}
// 检查权限
checkPermission($permissions, $userPermissions);
?>
在这个示例中,我们首先定义了一个权限树结构 $permissions
和一个用户权限 $userPermissions
。然后定义了一个递归函数 checkPermission
来逐层检查权限树和用户权限是否匹配。最后调用 checkPermission
函数来检查权限。如果权限不匹配,则输出提示信息。
请根据实际情况调整权限树和用户权限,并根据需要修改递归函数中的逻辑。
