从搜索的字符串PHP中删除常用单词

好的,所以我有一串由空格分隔的单词,即

$commonwords =’a,an,and,I,it,is,do,does,for,from,go,how,the,etc’;

我收到了来自$_POST [‘searchquery’]的搜索查询;

我想从搜索字符串中删除任何常用单词,我要查找的最终结果将是更简洁的关键字,然后我可以使用它来查询数据库.

因此,如果用户搜索“我如何搜索文件”

当删除所有常用单词时,该字符串将成为“搜索文件”.

解决方法:

这将有效但你必须在你的$commonwords中添加大写的“how”
    

$commonwords = 'a,an,and,I,it,is,do,does,for,from,go,how,the,etc';

$commonwords = explode(",", $commonwords);


$search = "How do I search for files";

$search = explode(" ", $search);

foreach($search as $value){
    if(!in_array($value, $commonwords)){
        echo "$value<br/>";
        $query[] = $value;
    }
}   


    $query = implode(" ", $query);

    echo $query;
?>
