推荐答案
使用 array_unique 函数.
Use the array_unique function.
这是一个多维array_unique函数的实现.
Here is an implentation of a multi-dimensional array_unique function.
function super_unique($array)
{
$result = array_map("unserialize", array_unique(array_map("serialize", $array)));
foreach ($result as $key => $value)
{
if ( is_array($value) )
{
$result[$key] = super_unique($value);
}
}
return $result;
}
未测试，来自功能手册中的注释.
Not tested, from the comments in the function manual.
