多个array_filter和strpos [英] Multiple array_filter and strpos

问题描述

我想返回不包含字符列表的数组。

I want to return array that does not contains a list of characters.

下面的代码对于一个关键字（'bc'）。

Below code works fine for one keyword ('bc').

$array = array("abc", "def", "ghi");
$filterArray = array_filter($array, function ($var) {return(strpos($var, 'bc') === false);});
print_r($filterArray);

但是，当我尝试使用<$ c $过滤掉多个关键字时，以下代码不起作用c> $ excludeKeyword_arr 和 foreach 。

However, below code does not work when I try to filter out multiple keywords by using $excludeKeyword_arr and foreach.

$array = array("abc", "def", "ghi");
$excludeKeyword_arr = ("ab", "de");
foreach($excludeKeyword_arr as $exclude){
    $filterArray = array_filter($array, function ($var) {return(strpos($var, $exclude) === false);});
}
print_r($filterArray);

应为返回数组，而不是布尔类型。

It should be return array instead of boolean type.

推荐答案

您可以使用preg_grep进行相反的操作，并匹配具有 bc 或的对象de 然后array_diff。

You can use preg_grep which will do the opposite and match the ones that has bc or de then array_diff.

$array = array("abc", "def", "ghi");
$excludeKeyword_arr = array("bc", "de");
$exclude_values = preg_grep("/". implode("|", $excludeKeyword_arr) . "/", $array);
$filterArray = array_diff($array, $values_with_bc);

print_r($filterArray); // [ 2 => "ghi"]
