PHP 和 MySQL - 创建表

PHP 使用 mysqli query() 或 mysql_query() 函数创建 MySQL 表。 该函数采用两个参数，成功时返回 TRUE，失败时返回 FALSE。

语法

$mysqli->query($sql,$resultmode)

示例

尝试以下示例来创建表 −

将以下示例复制并粘贴为 mysql_example.php −

<html>
   <head>
      <title>Creating MySQL Table</title>
   </head>
   <body>
      <?php
         $dbhost = 'localhost';
         $dbuser = 'root';
         $dbpass = 'root@123';
         $dbname = 'TUTORIALS';
         $mysqli = new mysqli($dbhost, $dbuser, $dbpass, $dbname);
         
         if($mysqli->connect_errno ) {
            printf("Connect failed: %s<br />", $mysqli->connect_error);
            exit();
         }
         printf('Connected successfully.<br />');
         $sql = "CREATE TABLE tutorials_tbl( ".
            "tutorial_id INT NOT NULL AUTO_INCREMENT, ".
            "tutorial_title VARCHAR(100) NOT NULL, ".
            "tutorial_author VARCHAR(40) NOT NULL, ".
            "submission_date DATE, ".
            "PRIMARY KEY ( tutorial_id )); ";
         if ($mysqli->query($sql)) {
            printf("Table tutorials_tbl created successfully.<br />");
         }
         if ($mysqli->errno) {
            printf("Could not create table: %s<br />", $mysqli->error);
         }
         $mysqli->close();
      ?>
   </body>
</html>

输出

访问部署在 apache Web 服务器上的 mysql_example.php 并验证输出。

Connected successfully.
Table tutorials_tbl created successfully.
