Question

我有像这样的代码

$words2= 'If you want to have a preformatted block within a list, indent by eight spaces.';

$forbiddenwords=array("word1","word2");

foreach($words2 as $b=>$v)
{
    if(in_array($v, $forbidden) ){
    unset($words2[$b] );

    }
}

$words2 = array_values($words2);

$words2=implode(' ',$words2);

$words2 = implode(' ',array_chunk(mb_split('\s', $words2), 2));

echo "<pre>";
print_r($words2);
echo "</pre>";

我想要的是创建一个数组，其中每个值都包含字符串中的2个单词。上面的代码不起作用-implode（）不能使用关联数组 - 我想要的结果就是那样

array (
$words2[0]=>'If you'
$words2[1]=>'you want'
$words2[1]=>'want to'
...
)

在删除列入黑名单的单词和构建单词对数组时，你的内容过于复杂。

删除黑名单：

$inputWords = mb_split('\s+', 'If you want to have a preformatted block...');
$forbiddenWords = array("want", "have");

$filtered = array_diff($inputWords, $forbiddenWords); // removes blacklisted

将每2个已过滤的单词加入字符串：

$pairs = array_chunk($filtered, 2); // array of arrays
$pairs = array_map(function($a) { return implode(' ', $a); }, $pairs);

在每个数组值中获取2个单词
