数组切片$ data，1,2对我来说是什么等价物？

如何解决数组切片$ data，1,2对我来说是什么等价物？

| 码：

$data = array(\"vanilla\",\"strawBerry\",\"mango\",\"peaches\");
print_r(array_slice($data,1,2));


Output:
Array
(
[0] => strawBerry
[1] => mango
)

就我而言：

$data = array(\"vanilla\",\"peaches\");
$sub_set_data = array( \"strawBerry\",\"mango\");

输出将是剩余数组：      

array(\"vanilla\",\"peaches\");

编辑：

NOT array diff it look like the minus operator 7-3 = 4 or $C = $A-$B

python概念：

>>> A           = [6,7,8,9,10,11,12]
>>> subset_of_A  = [6,12];
>>> set(A) - set(subset_of_A)
set([8,7])
>>> 

我该怎么办？     

解决方法

看来您需要

array_diff

<?php
$array1 = array(\"a\" => \"green\",\"red\",\"blue\",\"red\");
$array2 = array(\"b\" => \"green\",\"yellow\",\"red\");
$result = array_diff($array1,$array2);

print_r($result);
?>

结果：

Array
(
    [1] => blue
)
