解决方案
使用 array_unique 功能。
下面是一个多维array_unique函数的一个implentation
函数super_unique（$数组）
{
$结果= array_map（反序列化，array_unique（array_map（连载，$阵列）））; 的foreach（$结果为$关键=＆GT; $值）
{
如果（is_array（$值））
{
$结果[$关键] = super_unique（$值）;
}
} 返回$结果;
}
没测试过，从函数手册中的注释。
I was wondering if anyone could help me out, I'm trying to find a script that will check my entire array and remove any duplicates if required, then spit out the array in the same format.
Here's an example of my array (as you will see there are some duplicates):

解决方案
Use the array_unique function.
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;
}
Not tested, from the comments in the function manual.
