我使用以下代码，但似乎每当我在文章字段中使用单引号（'）或双引号（“）时( $_POST['article'] )除非我使用 \' 或者 \" 以便查询将其作为文本的一部分进行读取。。有什么代码我可以写，使它考虑到 $_POST['article'] 作为全文？这是我的密码：

<?php
require_once ('connection.php');

            $title=$_POST['title'];
            $article=$_POST['article'];

            if($category!="")
            {
                $query = "SELECT count( id ) as num FROM article;";
                $result = mysqli_query($conn, $query);

                /* numeric array */
                $row = mysqli_fetch_array($result, MYSQLI_NUM);
                if($row[0]==0)
                {
                    $newId=0;
                }else{
                    $query = "SELECT MAX( id ) as max FROM article;";
                    $result = mysqli_query($conn, $query);

                    /* numeric array */
                    $row = mysqli_fetch_array($result, MYSQLI_NUM);
                    $newId = $row[0] +1;
                }
                $sql="INSERT INTO `article`(`id`, `title`, `text`) 
                                            VALUES ('".$newId."','".$title."','".$article."')";
                $result = $conn->query($sql);
                if ($conn->query($sql) === TRUE) {
                    header("Location: ArticleSent.php");
                    $conn->close();
                    exit();
                } else {
                    echo "Error: " . $sql . "<br>" . $conn->error;
                    $conn->close();
                    exit();
                }
            }
            else
            {
                header("Location: categoryrequired.php");
                $conn->close();
                exit();
            }

 ?>
