写文档的时候需要附上数据库字典，于是找到个轻松的生成方式：PHP脚本，这里mark一下。配置好数据源放到apache的DocumentRoot访问即可。代码：

<?php
/**
* 生成mysql数据字典
*/

//配置数据库
$dbserver="";
$dbusername="";
$dbpassword="";
$database = '';
//其他配置
$title = '数据字典';

$mysql_conn = @mysql_connect("$dbserver", "$dbusername", "$dbpassword") or die("Mysql connect is error.");
mysql_select_db($database, $mysql_conn);
mysql_query('SET NAMES utf8', $mysql_conn);
$table_result = mysql_query('show tables', $mysql_conn);
//取得所有的表名
while ($row = mysql_fetch_array($table_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}'";
$table_result = mysql_query($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}'";

$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);

$html = '';
//循环所有表
foreach ($tables AS $k=>$v) {
//$html .= '<p><h2>'. $v['TABLE_COMMENT'] . ' </h2>';
$html .= '<table  border="1" cellspacing="0" cellpadding="0" align="center">';
$html .= '<caption>' . $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 .= '<tr><td class="c1">' . $f['COLUMN_NAME'] . '</td>';
$html .= '<td class="c2">' . $f['COLUMN_TYPE'] . '</td>';
$html .= '<td class="c3"> ' . $f['COLUMN_DEFAULT'] . '</td>';
$html .= '<td class="c4"> ' . $f['IS_NULLABLE'] . '</td>';
$html .= '<td class="c5">' . ($f['EXTRA']=='auto_increment'?'是':' ') . '</td>';
$html .= '<td class="c6"> ' . $f['COLUMN_COMMENT'] . '</td>';
$html .= '</tr>';
}
$html .= '</tbody></table></p>';
}

//输出
echo '<html>
<head>
<title>'.$title.'</title>
<style>
body,td,th {font-family:"宋体"; font-size:12px;}
table{border-collapse:collapse;border:1px solid #CCC;background:#efefef;}
table caption{text-align:left; background-color:#fff; line-height:2em; font-size:14px; font-weight:bold; }
table th{text-align:left; font-weight:bold;height:26px; line-height:26px; font-size:12px; border:1px solid #CCC;}
table td{height:20px; font-size:12px; border:1px solid #CCC;background-color:#fff;}
.c1{ width: 120px;}
.c2{ width: 120px;}
.c3{ width: 70px;}
.c4{ width: 80px;}
.c5{ width: 80px;}
.c6{ width: 270px;}
</style>
</head>
<body>';
echo '<h1 style="text-align:center;">'.$title.'</h1>';
echo $html;
echo '</body></html>';

?>
