<&#63;php
/**

 */
header("Content-type:text/html;charset=utf-8");
// 配置数据库
$database = array();
$database['DB_HOST'] = 'localhost';
$database['DB_NAME'] = 'test';
$database['DB_USER'] = 'root';
$database['DB_PWD'] = '';
$mysql_conn = @mysql_connect("{$database['DB_HOST']}", "{$database['DB_USER']}", "{$database['DB_PWD']}") or die("Mysql connect is error.");
mysql_select_db($database['DB_NAME'], $mysql_conn);
$result = mysql_query('show tables', $mysql_conn);
mysql_query("set names utf8");
// 取得所有表名
while ($row = mysql_fetch_array($result))
{
  $tables[]['TABLE_NAME'] = $row[0];
}
// 循环取得所有表的备注及表中列消息
foreach($tables as $k => $v)
{
  $sql = 'SELECT * FROM ';
  $sql .= 'information_schema.TABLES ';
  $sql .= 'WHERE ';
  $sql .= "table_name = '{$v['TABLE_NAME']}' AND table_schema = '{$database['DB_NAME']}'";
  $table_result = mysql_query($sql, $mysql_conn);
  while ($t = mysql_fetch_array($table_result))
  {
    $tables[$k]['TABLE_COMMENT'] = $t['TABLE_COMMENT'];
  }
  $sql = 'SELECT * FROM ';
  $sql .= 'information_schema.COLUMNS ';
  $sql .= 'WHERE ';
  $sql .= "table_name = '{$v['TABLE_NAME']}' AND table_schema = '{$database['DB_NAME']}'";
  $fields = array();
  $field_result = mysql_query($sql, $mysql_conn);
  while ($t = mysql_fetch_array($field_result))
  {
    $fields[] = $t;
  }
  $tables[$k]['COLUMN'] = $fields;
}
mysql_close($mysql_conn);
$html = '';
// 循环所有表
//print_r($tables);
foreach($tables as $k => $v)
{
  $html .= '<table border="1" cellspacing="0" cellpadding="0" align="center">';
  $html .= '<caption>表名：' . $v['TABLE_NAME'] . ' ' . $v['TABLE_COMMENT'] . '</caption>';
  $html .= '<tbody><tr><th>字段名</th><th>数据类型</th><th>默认值</th><th>允许非空</th><th>自动递增</th><th>备注</th></tr>';
  $html .= '';
  foreach($v['COLUMN'] AS $f)
  {
    $html .= '<td class="c1">' . $f['COLUMN_NAME'] . '</td>';

    $html .= '</tr>';
  }
  $html .= '</tbody></table></p>';
}
