 Array ( [0] => db [1] => es [2] => fs [3] => rp [4] => ti [5] => wb )////array $a
 Array ( [0] => es [1] => db [2] => fs ) ///array $b

我需要比较数组$b和$a，并将$b中缺失的数组放入新的数组$c 中

 $c=array();

使用array_diff()

$c = array_diff($array1, $array2);

您可以使用array_diff()

$a =  array ( [0] => db [1] => es [2] => fs [3] => rp [4] => ti [5] => wb );
$b =  array ( [0] => es [1] => db [2] => fs ) ///array $b
$c = array_dif ( $a , $b );
