php删除数组中的重复项

我想知道是否有人可以帮助我，我试图找到一个脚本，将检查我的整个数组，并删除任何重复如果需要，然后吐出阵列在相同的格式。php删除数组中的重复项

这里是我的阵列的例子（你会看到有一些重复）：

你有很多嵌套数组。你的意思是重复的？例如。第一个子数组包含一个ID为“57”的对象。这是否意味着，这个对象应该在第二个（和所有进一步的）子阵列中被删除？ – 2010-05-18 21:35:17

*可能重复*：http://stackoverflow.com/questions/307674/how-to-remove-duplicate-values-from-a-multi-dimensional-array-in-php – 2010-05-18 21:38:07

是的，这就是我之后..我知道它是多维的，但是如果有任何来自任何子阵列的任何东西的重复，它应该被删除:) – SoulieBaby 2010-05-18 21:38:10

使用array_unique功能。

这是一个多维array_unique函数的实现。

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; 
}

未经测试，来自功能手册中的注释。

我试过了，但它仍然显示重复的 – SoulieBaby 2010-05-18 21:40:13

+1，但是这似乎非常熟悉（http://stackoverflow.com/questions/1247950/how-to-remove-duplicated-2 -dimension-array-in-php/1248189＃1248189）... xP – 2010-05-18 21:40:16

您需要将对象转换为数组并使用'array_merge'。 – 2010-05-18 21:42:38

您可以通过执行从数组中删除重复项：

$array = array_values(array_unique($array));

这是否适用于多维数组？我不这么认为... – 2010-05-18 21:37:17

我的PHP的生疏，但这样的事情应该工作：使用

function makeUniqueBidArray(&$array) 
{ 
    $tempArray = array(); 
    foreach($array as $bidArray) { 
    foreach($bidArray as $bid) { 
     if (isset($tempArray[$bid->bid]) { 
     unset($bid); 
     } else { 
     $tempArray[$bid->bid] = $bid->name; 
     } 
    } 
    } 
}

停止，导致重复自己的阵列划分功能和阅读array_chunk

php手册页试试这个，它与大型阵列：

$original = array('one', 'two', 'three', 'four', 'five', 'two', 'four'); 
$filtered = array(); 
foreach ($original as $key => $value){ 
    if(in_array($value, $filtered)){ 
     continue; 
    } 
    array_push($filtered, $value); 
} 

print_r($filtered);

输出：

Array 
(
    [0] => one 
    [1] => two 
    [2] => three 
    [3] => four 
    [4] => five 
)
