Question

我想更新identifier_flag字段中的以下字词，有没有比我现有的更简单的方法呢？

$temp_query = "select * from faq"; 
$sql = mysqli_query($connection, $temp_query);
while($row = mysqli_fetch_assoc($sql)){
    if(preg_match("/price/", $row['question'])){
        $update = "update faq set identifier_flag = 'price' where id = '".$row['id']."'";
        mysqli_query($connection, $update);
    }
    if(preg_match("/colours/", $row['question'])){
        $update = "update faq set identifier_flag = 'colours' where id = '".$row['id']."'";
        mysqli_query($connection, $update);
    }
    if(preg_match("/versions/", $row['question'])){
        $update = "update faq set identifier_flag = 'versions' where id = '".$row['id']."'";
        mysqli_query($connection, $update);
    }
    if(preg_match("/oil/", $row['question'])){
        $update = "update faq set identifier_flag = 'oil' where id = '".$row['id']."'";
        mysqli_query($connection, $update);
    }
    if(preg_match("/seating/", $row['question'])){
        $update = "update faq set identifier_flag = 'seating' where id = '".$row['id']."'";
        mysqli_query($connection, $update);
    }

    if(preg_match("/warranty/", $row['question'])){
        $update = "update faq set identifier_flag = 'warranty' where id = '".$row['id']."'";
        mysqli_query($connection, $update);
    }
}

有很多方法可以做到这一点。我的大脑会像这样看到它

$temp_query = "select * from faq"; 
$flags = ['flag1','flag2'];
$sql = mysqli_query($connection,$temp_query);
while($row = mysqli_fetch_assoc($sql)){

    foreach($flags as $k=>$v) {
        if(preg_match('/'.$v.'/',$row['question'])) {
            $update = "update faq set identifier_flag = '{$v}' where id = '".$row['id']."'";
            mysqli_query($connection,$update);
            //continue; //to go to the next result
        }
    }
}
