array_diff:根据数组值计算数组的差集

arrayarray_diff(array$array1,array$array2[,array$...]) 根据数组的值,返回比较数组的差集,在第一个数组而不再其他数组的值 $arr1 = ['bb'='bbb','a'='aaa','e'='ccc','d'='ddd'];$arr2 = ['c'='bbb','d'='ccc'];$arr = array_diff($arr1,$arr2);echo 'pre

array array_diff ( array $array1 , array $array2 [, array $... ] )
根据数组的值,返回比较数组的差集,在第一个数组而不再其他数组的值

$arr1 = ['bb'=>'bbb','a'=>'aaa','e'=>'ccc','d'=>'ddd'];
$arr2 = ['c'=>'bbb','d'=>'ccc'];

$arr = array_diff($arr1,$arr2);

echo '
';
print_r($arr);

result:
Array
(
    [a] => aaa
    [d] => ddd
)
