有时候我们拿到别人的数据库，却没有数据字典，这个php小程序帮你轻松解决。

代码是网上找到的，当然，这段代码也仅仅是生成了数据字典，视图，存储过程等等是木有的哦。

<?php
/**
 * 生成mysql数据字典
 */

//配置数据库
$dbserver   = "127.0.0.1";
$dbusername = "root";
$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>

echo '<h1 style="text-align:center;">'.$title.'</h1>';
echo $html;
echo '</body></html>';
