简介一键自动生成项目的mysql数据字典

将下方代码保存为mysql.php放入网站根目录，然后修改连接配置，最后浏览器访问即可得到数据字典，可以通过网页保存为文档。

<?php

//配置数据库
$dbserver   = "127.0.0.1";
$dbusername = "root";
$dbpassword = "root";
$database   = "db_name";

//其他配置
$mysql_conn = mysqli_connect("$dbserver", "$dbusername", "$dbpassword") or die("Mysql connect is error.");
mysqli_select_db($mysql_conn, $database);
mysqli_query($mysql_conn, 'SET NAMES utf8');
$table_result = mysqli_query($mysql_conn, 'show tables');

$no_show_table = array(); //不需要显示的表
$no_show_field = array(); //不需要显示的字段

//取得所有的表名
$tables = array();
while ($row = mysqli_fetch_array($table_result)) {
    if (!in_array($row[0], $no_show_table)) {
        $tables[]['TABLE_NAME'] = $row[0];
    }
}

//替换所有表的表前缀
/*if(!empty($_GET['prefix'])){

$string = explode('_',$tableName);
if($string[0] != $prefix){
$string[0] = $prefix;
$newTableName = implode('_', $string);
mysql_query('rename table '.$tableName.' TO '.$newTableName);
}
}
echo "替换成功！";exit();
