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 .= '</tr>';    }    $html .= '</tbody></table></p>';}//输出echo '<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>'.$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>';?>

运行后的结果：
